The United States of America (also called the United States, the States, the U.S., the USA, and America) is a federal constitutional republic comprising fifty states and a federal district. The country is mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2010 GDP of $14.780 trillion (23% of nominal global GDP and 20% of global GDP at purchasing-power parity).

Indigenous peoples have inhabited what is now the mainland United States for between 12,000 and 40,000 years since the Paleo-Indians crossed the Bearing land bridge from Asia to North America. This Native American population was greatly reduced by disease and warfare after European contact. The United States was founded by thirteen British colonies located along the Atlantic seaboard. On July 4, 1776, they issued the Declaration of Independence, which proclaimed their right to self-determination and their establishment of a cooperative union. The rebellious states defeated the British Empire in the American Revolution, the first successful colonial war of independence. The current United States Constitution was adopted on September 17, 1787; its ratification the following year made the states part of a single republic with a strong central government. The Bill of Rights, comprising ten constitutional amendments guaranteeing many fundamental civil rights and freedoms, was ratified in 1791.

Through the 19th century, the United States displaced native tribes, acquired the Louisiana territory from France, Florida from Spain, part of the Oregon Country from the United Kingdom, Alta California and New Mexico from Mexico, Alaska from Russia, and annexed the Republic of Texas and the Republic of Hawaii. Disputes between the agrarian South and industrial North over the expansion of the institution of slavery and states' rights provoked the Civil War of the 1860s. The North's victory prevented a permanent split of the country and led to the end of legal slavery in the United States. By the 1870s, its national economy was the world's largest. The Spanish–American War and World War I confirmed the country's status as a military power. It emerged from World War II as the first country with nuclear weapons and a permanent member of the United Nations Security Council. The end of the Cold War and the dissolution of the Soviet Union left the United States as the sole superpower. The country accounts for 41% of global military spending, and it is a leading economic, political, and cultural force in the world.

Etymology

In 1507, German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere "America" after Italian explorer and cartographer Amerigo Vespucci. The former British colonies first used the country's modern name in the 1776 Declaration of Independence, the "unanimous Declaration of the thirteen united States of America". On November 15, 1777, the Second Continental Congress adopted the Articles of Confederation, which states, "The Stile of this Confederacy shall be 'The United States of America.'" The Franco-American treaties of 1778 used "United States of North America", but from July 11, 1778, "United States of America" was used on the country's bills of exchange, and it has been the official name ever since.

The short form "United States" is also standard. Other common forms include the "U.S.", the "USA", and "America". Colloquial names include the "U.S. of A." and, internationally, the "States". "Columbia", a once popular name for the United States, derives from Christopher Columbus; it appears in the name "District of Columbia".

The standard way to refer to a citizen of the United States is as an "American". Although "United States" is the official appositional term, "American" and "U.S." are more commonly used to refer to the country adjectivally ("American values", "U.S. forces"). "American" is rarely used in English to refer to people not connected to the United States.

The phrase "United States" was originally treated as plural—e.g., "the United States are"—including in the Thirteenth Amendment to the United States Constitution, ratified in 1865. It became common to treat it as singular—e.g., "the United States is"—after the end of the Civil War. The singular form is now standard; the plural form is retained in the idiom "these United States".

Geography and environment

The land area of the contiguous United States is approximately . Alaska, separated from the contiguous United States by Canada, is the largest state at . Hawaii, occupying an archipelago in the central Pacific, southwest of North America, has just over . The United States is the world's third or fourth largest nation by total area (land and water), ranking behind Russia and Canada and just above or below China. The ranking varies depending on how two territories disputed by China and India are counted and how the total size of the United States is measured: calculations range from to to . Including only land area, the United States is third in size behind Russia and China, just ahead of Canada.

The coastal plain of the Atlantic seaboard gives way further inland to deciduous forests and the rolling hills of the Piedmont. The Appalachian Mountains divide the eastern seaboard from the Great Lakes and the grasslands of the Midwest. The Mississippi–Missouri River, the world's fourth longest river system, runs mainly north–south through the heart of the country. The flat, fertile prairie of the Great Plains stretches to the west, interrupted by a highland region in the southeast. The Rocky Mountains, at the western edge of the Great Plains, extend north to south across the country, reaching altitudes higher than 14,000 feet (4,300 m) in Colorado. Farther west are the rocky Great Basin and deserts such as the Mojave. The Sierra Nevada and Cascade mountain ranges run close to the Pacific coast. At 20,320 feet (6,194 m), Alaska's Mount McKinley is the tallest peak in the country and in North America. Active volcanoes are common throughout Alaska's Alexander and Aleutian Islands, and Hawaii consists of volcanic islands. The supervolcano underlying Yellowstone National Park in the Rockies is the continent's largest volcanic feature. The United States, with its large size and geographic variety, includes most climate types. To the east of the 100th meridian, the climate ranges from humid continental in the north to humid subtropical in the south. The southern tip of Florida is tropical, as is Hawaii. The Great Plains west of the 100th meridian are semi-arid. Much of the Western mountains are alpine. The climate is arid in the Great Basin, desert in the Southwest, Mediterranean in coastal California, and oceanic in coastal Oregon and Washington and southern Alaska. Most of Alaska is subarctic or polar. Extreme weather is not uncommon—the states bordering the Gulf of Mexico are prone to hurricanes, and most of the world's tornadoes occur within the country, mainly in the Midwest's Tornado Alley.

The U.S. ecology is considered "megadiverse": about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland. The United States is home to more than 400 mammal, 750 bird, and 500 reptile and amphibian species. About 91,000 insect species have been described. The Endangered Species Act of 1973 protects threatened and endangered species and their habitats, which are monitored by the United States Fish and Wildlife Service. There are fifty-eight national parks and hundreds of other federally managed parks, forests, and wilderness areas. Altogether, the government owns 28.8% of the country's land area. Most of this is protected, though some is leased for oil and gas drilling, mining, logging, or cattle ranching; 2.4% is used for military purposes.

Political divisions

The United States is a federal union of fifty states. The original thirteen states were the successors of the thirteen colonies that rebelled against British rule. Early in the country's history, three new states were organized on territory separated from the claims of the existing states: Kentucky from Virginia; Tennessee from North Carolina; and Maine from Massachusetts. Most of the other states have been carved from territories obtained through war or purchase by the U.S. government. One set of exceptions comprises Vermont, Texas, and Hawaii: each was an independent republic before joining the union. During the American Civil War, West Virginia broke away from Virginia. The most recent state—Hawaii—achieved statehood on August 21, 1959. The states do not have the right to secede from the union.

The states compose the vast bulk of the U.S. land mass; the two other areas considered integral parts of the country are the District of Columbia, the federal district where the capital, Washington, is located; and Palmyra Atoll, an uninhabited but incorporated territory in the Pacific Ocean. The United States also possesses five major overseas territories: Puerto Rico and the United States Virgin Islands in the Caribbean; and American Samoa, Guam, and the Northern Mariana Islands in the Pacific. Those born in the major territories (except for American Samoa) possess U.S. citizenship. American citizens residing in the territories have many of the same rights and responsibilities as citizens residing in the states; however, they are generally exempt from federal income tax, may not vote for president, and have only nonvoting representation in the U.S. Congress.

History

Native American and European settlement

The indigenous peoples of the U.S. mainland, including Alaska Natives, are believed to have migrated from Asia, beginning between 12,000 and 40,000 years ago. Some, such as the pre-Columbian Mississippian culture, developed advanced agriculture, grand architecture, and state-level societies. After Europeans began settling the Americas, many millions of indigenous Americans died from epidemics of imported diseases such as smallpox.

In 1492, Genoese explorer Christopher Columbus, under contract to the Spanish crown, reached several Caribbean islands, making first contact with the indigenous people. On April 2, 1513, Spanish conquistador Juan Ponce de León landed on what he called "La Florida"—the first documented European arrival on what would become the U.S. mainland. Spanish settlements in the region were followed by ones in the present-day southwestern United States that drew thousands through Mexico. French fur traders established outposts of New France around the Great Lakes; France eventually claimed much of the North American interior, down to the Gulf of Mexico. The first successful English settlements were the Virginia Colony in Jamestown in 1607 and the Pilgrims' Plymouth Colony in 1620. The 1628 chartering of the Massachusetts Bay Colony resulted in a wave of migration; by 1634, New England had been settled by some 10,000 Puritans. Between the late 1610s and the American Revolution, about 50,000 convicts were shipped to Britain's American colonies. Beginning in 1614, the Dutch settled along the lower Hudson River, including New Amsterdam on Manhattan Island.

In 1674, the Dutch ceded their American territory to England; the province of New Netherland was renamed New York. Many new immigrants, especially to the South, were indentured servants—some two-thirds of all Virginia immigrants between 1630 and 1680. By the turn of the 18th century, African slaves were becoming the primary source of bonded labor. With the 1729 division of the Carolinas and the 1732 colonization of Georgia, the thirteen British colonies that would become the United States of America were established. All had local governments with elections open to most free men, with a growing devotion to the ancient rights of Englishmen and a sense of self-government stimulating support for republicanism. All legalized the African slave trade. With high birth rates, low death rates, and steady immigration, the colonial population grew rapidly. The Christian revivalist movement of the 1730s and 1740s known as the Great Awakening fueled interest in both religion and religious liberty. In the French and Indian War, British forces seized Canada from the French, but the francophone population remained politically isolated from the southern colonies. Excluding the Native Americans (popularly known as "American Indians"), who were being displaced, those thirteen colonies had a population of 2.6 million in 1770, about one-third that of Britain; nearly one in five Americans were black slaves. Though subject to British taxation, the American colonials had no representation in the Parliament of Great Britain.

Independence and expansion

Tensions between American colonials and the British during the revolutionary period of the 1760s and early 1770s led to the American Revolutionary War, fought from 1775 to 1781. On June 14, 1775, the Continental Congress, convening in Philadelphia, established a Continental Army under the command of George Washington. Proclaiming that "all men are created equal" and endowed with "certain unalienable Rights", the Congress adopted the Declaration of Independence, drafted largely by Thomas Jefferson, on July 4, 1776. That date is now celebrated annually as America's Independence Day. In 1777, the Articles of Confederation established a weak confederal government that operated until 1789.

After the British defeat by American forces assisted by the French and Spanish, Great Britain recognized the independence of the United States and the states' sovereignty over American territory west to the Mississippi River. Those wishing to establish a strong national government with powers of taxation organized a constitutional convention in 1787. The United States Constitution was ratified in 1788, and the new republic's first Senate, House of Representatives, and president—George Washington—took office in 1789. The Bill of Rights, forbidding federal restriction of personal freedoms and guaranteeing a range of legal protections, was adopted in 1791.

Attitudes toward slavery were shifting; a clause in the Constitution protected the transatlantic slave trade only until 1808. The Northern states abolished slavery between 1780 and 1804, leaving the slave states of the South as defenders of the "peculiar institution". The Second Great Awakening, beginning about 1800, made evangelicalism a force behind various social reform movements, including abolitionism.

Americans' eagerness to expand westward prompted a long series of Indian Wars. The Louisiana Purchase of French-claimed territory under President Thomas Jefferson in 1803 almost doubled the nation's size. The War of 1812, declared against Britain over various grievances and fought to a draw, strengthened U.S. nationalism. A series of U.S. military incursions into Florida led Spain to cede it and other Gulf Coast territory in 1819. The Trail of Tears in the 1830s exemplified the Indian removal policy that stripped the native peoples of their land. The United States annexed the Republic of Texas in 1845, amid a period when the concept of Manifest Destiny was becoming popular. The 1846 Oregon Treaty with Britain led to U.S. control of the present-day American Northwest. The U.S. victory in the Mexican-American War resulted in the 1848 cession of California and much of the present-day American Southwest. The California Gold Rush of 1848–49 further spurred western migration. New railways made relocation easier for settlers and increased conflicts with Native Americans. Over a half-century, up to 40 million American bison, or buffalo, were slaughtered for skins and meat and to ease the railways' spread. The loss of the buffalo, a primary resource for the plains Indians, was an existential blow to many native cultures.

Civil War and industrialization

Tensions between slave and free states mounted with arguments over the relationship between the state and federal governments, as well as violent conflicts over the spread of slavery into new states. Abraham Lincoln, candidate of the largely antislavery Republican Party, was elected president in 1860. Before he took office, seven slave states declared their secession—which the federal government maintained was illegal—and formed the Confederate States of America. With the Confederate attack upon Fort Sumter, the Civil War began and four more slave states joined the Confederacy. Lincoln's Emancipation Proclamation in 1863 declared slaves in the Confederacy to be free. Following the Union victory in 1865, three amendments to the U.S. Constitution ensured freedom for the nearly four million African Americans who had been slaves, made them citizens, and gave them voting rights. The war and its resolution led to a substantial increase in federal power. The war remains the deadliest conflict in American history, resulting in the deaths of 620,000 soldiers.

After the war, the assassination of Lincoln radicalized Republican Reconstruction policies aimed at reintegrating and rebuilding the Southern states while ensuring the rights of the newly freed slaves. The resolution of the disputed 1876 presidential election by the Compromise of 1877 ended Reconstruction; Jim Crow laws soon disenfranchised many African Americans. In the North, urbanization and an unprecedented influx of immigrants from Southern Southern and Eastern Europe hastened the country's industrialization. The wave of immigration, lasting until 1929, provided labor and transformed American culture. National infrastructure development spurred economic growth. The 1867 Alaska Purchase from Russia completed the country's mainland expansion. The Wounded Knee Massacre in 1890 was the last major armed conflict of the Indian Wars. In 1893, the indigenous monarchy of the Pacific Kingdom of Hawaii was overthrown in a coup led by American residents; the United States annexed the archipelago in 1898. Victory in the Spanish–American War the same year demonstrated that the United States was a world power and led to the annexation of Puerto Rico, Guam, and the Philippines. The Philippines gained independence a half-century later; Puerto Rico and Guam remain U.S. territories.

World War I, Great Depression, and World War II

At the outbreak of World War I in 1914, the United States remained neutral. Most Americans sympathized with the British and French, although many opposed intervention. In 1917, the United States joined the Allies, and the American Expeditionary Forces helped to turn the tide against the Central Powers. After the war, the Senate did not ratify the Treaty of Versailles, which established the League of Nations. The country pursued a policy of unilateralism, verging on isolationism. In 1920, the women's rights movement won passage of a constitutional amendment granting women's suffrage. The prosperity of the Roaring Twenties ended with the Wall Street Crash of 1929 that triggered the Great Depression. After his election as president in 1932, Franklin D. Roosevelt responded with the New Deal, a range of policies increasing government intervention in the economy, including the establishment of the Social Security system. The Dust Bowl of the mid-1930s impoverished many farming communities and spurred a new wave of western migration. The United States, effectively neutral during World War II's early stages after Nazi Germany's invasion of Poland in September 1939, began supplying materiel to the Allies in March 1941 through the Lend-Lease program. On December 7, 1941, the Empire of Japan launched a surprise attack on Pearl Harbor, prompting the United States to join the Allies against the Axis powers as well as the internment of Japanese Americans by the thousands. Participation in the war spurred capital investment and industrial capacity. Among the major combatants, the United States was the only nation to become richer—indeed, far richer—instead of poorer because of the war. Allied conferences at Bretton Woods and Yalta outlined a new system of international organizations that placed the United States and Soviet Union at the center of world affairs. As victory was won in Europe, a 1945 international conference held in San Francisco produced the United Nations Charter, which became active after the war. The United States, having developed the first nuclear weapons, used them on the Japanese cities of Hiroshima and Nagasaki in August. Japan surrendered on September 2, ending the war.

Cold War and protest politics

The United States and Soviet Union jockeyed for power after World War II during the Cold War, dominating the military affairs of Europe through NATO and the Warsaw Pact, respectively. While they engaged in proxy wars and developed powerful nuclear arsenals, the two countries avoided direct military conflict. Resisting leftist land and income redistribution projects around the world, the United States often supported authoritarian governments. American troops fought Communist Chinese forces in the Korean War of 1950–53. The House Un-American Activities Committee pursued a series of investigations into suspected leftist subversion, while Senator Joseph McCarthy became the figurehead of anticommunist sentiment.

The 1961 Soviet launch of the first manned spaceflight prompted President John F. Kennedy's call for the United States to be first to land "a man on the moon", achieved in 1969. Kennedy also faced a tense nuclear showdown with Soviet forces in Cuba. Meanwhile, the United States experienced sustained economic expansion. A growing civil rights movement, symbolized and led by African Americans such as Rosa Parks, Martin Luther King, Jr., and James Bevel, used nonviolence to confront segregation and discrimination. Following Kennedy's assassination in 1963, the Civil Rights Act of 1964 and Voting Rights Act of 1965 were passed under President Lyndon B. Johnson. He also signed into law the Medicare and Medicaid programs. Johnson and his successor, Richard Nixon, expanded a proxy war in Southeast Asia into the unsuccessful Vietnam War. A widespread countercultural movement grew, fueled by opposition to the war, black nationalism, and the sexual revolution. Betty Friedan, Gloria Steinem, and others led a new wave of feminism that sought political, social, and economic equality for women.

As a result of the Watergate scandal, in 1974 Nixon became the first U.S. president to resign, to avoid being impeached on charges including obstruction of justice and abuse of power. The Jimmy Carter administration of the late 1970s was marked by stagflation and the Iran hostage crisis. The election of Ronald Reagan as president in 1980 heralded a rightward shift in American politics, reflected in major changes in taxation and spending priorities. His second term in office brought both the Iran-Contra scandal and significant diplomatic progress with the Soviet Union. The subsequent Soviet collapse ended the Cold War.

Contemporary era

Under President George H. W. Bush, the United States took a lead role in the UN–sanctioned Gulf War. The longest economic expansion in modern U.S. history—from March 1991 to March 2001—encompassed the Bill Clinton administration and the dot-com bubble. A civil lawsuit and sex scandal led to Clinton's impeachment in 1998, but he remained in office. The 2000 presidential election, one of the closest in American history, was resolved by a U.S. Supreme Court decision—George W. Bush, son of George H. W. Bush, became president.

On September 11, 2001, al-Qaeda terrorists struck the World Trade Center in New York City and The Pentagon near Washington, D.C., killing nearly three thousand people. In response, the Bush administration launched the global War on Terror, invading Afghanistan and removing the Taliban government and al-Qaeda training camps. Taliban insurgents continue to fight a guerrilla war. In 2002, the Bush administration began to press for regime change in Iraq on controversial grounds. Forces of a so-called Coalition of the Willing invaded Iraq in 2003, ousting Saddam Hussein. In 2005, Hurricane Katrina caused severe destruction along much of the Gulf Coast, devastating New Orleans. In 2008, amid a global economic recession, the first African American president, Barack Obama, was elected. In 2010, major health care and financial system reforms were enacted.

Government, elections, and politics

The United States is the world's oldest surviving federation. It is a constitutional republic and representative democracy, "in which majority rule is tempered by minority rights protected by law". The government is regulated by a system of checks and balances defined by the U.S. Constitution, which serves as the country's supreme legal document. In the American federalist system, citizens are usually subject to three levels of government, federal, state, and local; the local government's duties are commonly split between county and municipal governments. In almost all cases, executive and legislative officials are elected by a plurality vote of citizens by district. There is no proportional representation at the federal level, and it is very rare at lower levels.

The federal government is composed of three branches:

Legislative: The bicameral Congress, made up of the Senate and the House of Representatives, makes federal law, declares war, approves treaties, has the power of the purse, and has the power of impeachment, by which it can remove sitting members of the government.

Executive: The president is the commander-in-chief of the military, can veto legislative bills before they become law, and appoints the members of the Cabinet (subject to Senate approval) and other officers, who administer and enforce federal laws and policies.

Judicial: The Supreme Court and lower federal courts, whose judges are appointed by the president with Senate approval, interpret laws and overturn those they find unconstitutional.

The House of Representatives has 435 voting members, each representing a congressional district for a two-year term. House seats are apportioned among the states by population every tenth year. As of the 2000 census, seven states have the minimum of one representative, while California, the most populous state, has fifty-three. The Senate has 100 members with each state having two senators, elected at-large to six-year terms; one third of Senate seats are up for election every other year. The president serves a four-year term and may be elected to the office no more than twice. The president is not elected by direct vote, but by an indirect electoral college system in which the determining votes are apportioned to the states and the District of Columbia. The Supreme Court, led by the Chief Justice of the United States, has nine members, who serve for life.

The state governments are structured in roughly similar fashion; Nebraska uniquely has a unicameral legislature. The governor (chief executive) of each state is directly elected. Some state judges and cabinet officers are appointed by the governors of the respective states, while others are elected by popular vote.

The original text of the Constitution establishes the structure and responsibilities of the federal government and its relationship with the individual states. Article One protects the right to the "great writ" of habeas corpus, and Article Three guarantees the right to a jury trial in all criminal cases. Amendments to the Constitution require the approval of three-fourths of the states. The Constitution has been amended twenty-seven times; the first ten amendments, which make up the Bill of Rights, and the Fourteenth Amendment form the central basis of Americans' individual rights. All laws and governmental procedures are subject to judicial review and any law ruled in violation of the Constitution is voided. The principle of judicial review, not explicitly mentioned in the Constitution, was declared by the Supreme Court in ''Marbury v. Madison'' (1803).

Parties and ideology

The United States has operated under a two-party system for most of its history. For elective offices at most levels, state-administered primary elections choose the major party nominees for subsequent general elections. Since the general election of 1856, the major parties have been the Democratic Party, founded in 1824, and the Republican Party, founded in 1854. Since the Civil War, only one third-party presidential candidate—former president Theodore Roosevelt, running as a Progressive in 1912—has won as much as 20% of the popular vote.

Within American political culture, the Republican Party is considered center-right or "conservative" and the Democratic Party is considered center-left or "liberal". The states of the Northeast and West Coast and some of the Great Lakes states, known as "blue states", are relatively liberal. The "red states" of the South and parts of the Great Plains and Rocky Mountains are relatively conservative.

The winner of the 2008 presidential election, Democrat Barack Obama, is the 44th U.S. president. The 2010 midterm elections saw the Republican Party take control of the House and make gains in the Senate, where the Democrats retain the majority. In the 112th United States Congress, the Senate comprises 51 Democrats, two independents who caucus with the Democrats, and 47 Republicans; the House comprises 240 Republicans and 192 Democrats—three seats are vacant. There are 29 Republican and 20 Democratic state governors, as well as one independent.

Foreign relations and military

The United States exercises global economic, political, and military influence. It is a permanent member of the United Nations Security Council and New York City hosts the United Nations Headquarters. It is a member of the G8, G20, and Organisation for Economic Co-operation and Development. Almost all countries have embassies in Washington, D.C., and many have consulates around the country. Likewise, nearly all nations host American diplomatic missions. However, Cuba, Iran, North Korea, Bhutan, Libya, and the Republic of China (Taiwan) do not have formal diplomatic relations with the United States.

The United States has a "special relationship" with the United Kingdom and strong ties with Canada, Australia, New Zealand, the Philippines, Japan, South Korea, Israel, and several European countries. It works closely with fellow NATO members on military and security issues and with its neighbors through the Organization of American States and free trade agreements such as the trilateral North American Free Trade Agreement with Canada and Mexico. In 2008, the United States spent a net $25.4 billion on official development assistance, the most in the world. As a share of America's large gross national income (GNI), however, the U.S. contribution of 0.18% ranked last among twenty-two donor states. By contrast, private overseas giving by Americans is relatively generous.

The president holds the title of commander-in-chief of the nation's armed forces and appoints its leaders, the secretary of defense and the Joint Chiefs of Staff. The United States Department of Defense administers the armed forces, including the Army, Navy, Marine Corps, and Air Force. The Coast Guard is run by the Department of Homeland Security in peacetime and the Department of the Navy in time of war. In 2008, the armed forces had 1.4 million personnel on active duty. The Reserves and National Guard brought the total number of troops to 2.3 million. The Department of Defense also employed about 700,000 civilians, not including contractors.

Military service is voluntary, though conscription may occur in wartime through the Selective Service System. American forces can be rapidly deployed by the Air Force's large fleet of transport aircraft, the Navy's eleven active aircraft carriers, and Marine Expeditionary Units at sea with the Navy's Atlantic and Pacific fleets. The military operates 865 bases and facilities abroad, and maintains deployments greater than 100 active duty personnel in 25 foreign countries. The extent of this global military presence has prompted some scholars to describe the United States as maintaining an "empire of bases".

Total U.S. military spending in 2008, more than $600 billion, was over 41% of global military spending and greater than the next fourteen largest national military expenditures combined. The per capita spending of $1,967 was about nine times the world average; at 4% of GDP, the rate was the second-highest among the top fifteen military spenders, after Saudi Arabia. The proposed base Department of Defense budget for 2012, $553 billion, is a 4.2% increase over 2011; an additional $118 billion is proposed for the military campaigns in Iraq and Afghanistan. As of September 2010, the United States is scheduled to have 96,000 troops deployed to Afghanistan, and 50,000 to Iraq. As of July 25, 2011, the United States had suffered 4,474 military fatalities during the Iraq War, and 1,680 during the War in Afghanistan.

Economy

The United States has a capitalist mixed economy, which is fueled by abundant natural resources, a well-developed infrastructure, and high productivity. According to the International Monetary Fund, the U.S. GDP of $15 trillion constitutes 23% of the gross world product at market exchange rates and over 20% of the gross world product at purchasing power parity (PPP). Though larger than any other nation's, its national GDP is about 5% smaller than the GDP of the European Union at PPP in 2008. The country ranks ninth in the world in nominal GDP per capita and sixth in GDP per capita at PPP. The U.S. dollar is the world's primary reserve currency.

The United States is the largest importer of goods and third largest exporter, though exports per capita are relatively low. In 2008, the total U.S. trade deficit was $696 billion. Canada, China, Mexico, Japan, and Germany are its top trading partners. In 2007, vehicles constituted both the leading import and leading export commodity. China is the largest foreign holder of U.S. public debt.

In 2009, the private sector was estimated to constitute 55.3% of the economy, with federal government activity accounting for 24.1% and state and local government activity (including federal transfers) the remaining 20.6%. While its economy has reached a postindustrial level of development and its service sector constitutes 67.8% of GDP, the United States remains an industrial power. The leading business field by gross business receipts is wholesale and retail trade; by net income it is manufacturing. Chemical products are the leading manufacturing field. The United States is the third largest producer of oil in the world, as well as its largest importer. It is the world's number one producer of electrical and nuclear energy, as well as liquid natural gas, sulfur, phosphates, and salt. While agriculture accounts for just under 1% of GDP, the United States is the world's top producer of corn and soybeans. Coca-Cola and McDonald's are the two most recognized brands in the world.

In August 2010, the American labor force comprised 154.1 million people. With 21.2 million people, government is the leading field of employment. The largest private employment sector is health care and social assistance, with 16.4 million people. About 12% of workers are unionized, compared to 30% in Western Europe. The World Bank ranks the United States first in the ease of hiring and firing workers. In 2009, the United States had the third highest labor productivity per person in the world, behind Luxembourg and Norway. It was fourth in productivity per hour, behind those two countries and the Netherlands. Compared to Europe, U.S. property and corporate income tax rates are generally higher, while labor and, particularly, consumption tax rates are lower.

Income and human development

According to the United States Census Bureau, the pretax median household income in 2007 was $49,777. The median ranged from $65,469 among Asian American households to $32,584 among African American households. Using purchasing power parity exchange rates, the overall median is similar to the most affluent cluster of developed nations. After declining sharply during the middle of the 20th century, poverty rates have plateaued since the early 1970s, with 11–15% of Americans below the poverty line every year, and 58.5% spending at least one year in poverty between the ages of 25 and 75. In 2009, 43.6 million Americans lived in poverty.

The U.S. welfare state is one of the least extensive in the developed world, reducing both relative poverty and absolute poverty by considerably less than the mean for rich nations, though combined private and public social expenditures per capita are relatively high. While the American welfare state effectively reduces poverty among the elderly, it provides relatively little assistance to the young. A 2007 UNICEF study of children's well-being in twenty-one industrialized nations ranked the United States next to last.

Between 1947 and 1979, real median income rose by over 80% for all classes, with the incomes of poor Americans rising faster than those of the rich. Since 1980, the United States has witnessed strong increases in productivity, low unemployment, and low inflation. However, income gains since 1980 have been slower than in previous decades, less widely shared, and accompanied by increased economic insecurity. Median household income has increased for all classes since 1980, largely owing to more dual-earner households, the closing of the gender gap, and longer work hours, but growth has been slower and strongly tilted toward the very top (see graph). Consequently, the share of income of the top 1%—21.8% of total reported income in 2005—has more than doubled since 1980, leaving the United States with the greatest income inequality among developed nations. The top 1% pays 27.6% of all federal taxes, while the top 10% pays 54.7%. Wealth, like income, is highly concentrated: The richest 10% of the adult population possesses 69.8% of the country's household wealth, the second-highest share among developed nations. The top 1% possesses 33.4% of net wealth. In 2010 the United Nations Development Programme ranked the United States 12th among 139 countries on its inequality-adjusted human development index (IHDI), eight places lower than in the standard HDI.

Infrastructure

Science and technology

The United States has been a leader in scientific research and technological innovation since the late 19th century. In 1876, Alexander Graham Bell was awarded the first U.S. patent for the telephone. Thomas Edison's laboratory developed the phonograph, the first long-lasting light bulb, and the first viable movie camera. Nikola Tesla pioneered alternating current, the AC motor, and radio. In the early 20th century, the automobile companies of Ransom E. Olds and Henry Ford popularized the assembly line. The Wright brothers, in 1903, made the first sustained and controlled heavier-than-air powered flight.

The rise of Nazism in the 1930s led many European scientists, including Albert Einstein and Enrico Fermi, to immigrate to the United States. During World War II, the Manhattan Project developed nuclear weapons, ushering in the Atomic Age. The Space Race produced rapid advances in rocketry, materials science, and computers. IBM, Apple Computer, and Microsoft refined and popularized the personal computer. The United States largely developed the ARPANET and its successor, the Internet. Today, 64% of research and development funding comes from the private sector. The United States leads the world in scientific research papers and impact factor. Americans possess high levels of technological consumer goods, and almost half of U.S. households have broadband Internet access. The country is the primary developer and grower of genetically modified food, representing half of the world's biotech crops.

Transportation

Personal transportation is dominated by automobiles, which operate on a network of 13 million roads, including the world's longest highway system. The world's second largest automobile market, the United States has the highest rate of per-capita vehicle ownership in the world, with 765 vehicles per 1,000 Americans. About 40% of personal vehicles are vans, SUVs, or light trucks. The average American adult (accounting for all drivers and nondrivers) spends 55 minutes driving every day, traveling .

Mass transit accounts for 9% of total U.S. work trips, ranking last in a survey of 17 countries. While transport of goods by rail is extensive, relatively few people use rail to travel. Light rail development has increased in recent years but, like high speed rail, is below European levels. Bicycle usage for work commutes is minimal.

The civil airline industry is entirely privately owned and has been largely deregulated since 1978, while most major airports are publicly owned. The four largest airlines in the world by passengers carried are American; Southwest Airlines is number one. Of the world's thirty busiest passenger airports, sixteen are in the United States, including the busiest, Hartsfield-Jackson Atlanta International Airport.

Energy

The United States energy market is 29,000 terawatt hours per year. Energy consumption per capita is 7.8 tons of oil equivalent per year, the 10th highest rate in the world. In 2005, 40% of this energy came from petroleum, 23% from coal, and 22% from natural gas. The remainder was supplied by nuclear power and renewable energy sources. The United States is the world's largest consumer of petroleum. For decades, nuclear power has played a limited role relative to many other developed countries, in part due to public perception in the wake of a 1979 accident. In 2007, several applications for new nuclear plants were filed. The United States has 27% of global coal reserves.

Education

American public education is operated by state and local governments, regulated by the United States Department of Education through restrictions on federal grants. Children are required in most states to attend school from the age of six or seven (generally, kindergarten or first grade) until they turn eighteen (generally bringing them through twelfth grade, the end of high school); some states allow students to leave school at sixteen or seventeen. About 12% of children are enrolled in parochial or nonsectarian private schools. Just over 2% of children are homeschooled.

The United States has many competitive private and public institutions of higher education. According to prominent international rankings, 13 or 15 American colleges and universities are ranked among the top 20 in the world. There are also local community colleges with generally more open admission policies, shorter academic programs, and lower tuition. Of Americans twenty-five and older, 84.6% graduated from high school, 52.6% attended some college, 27.2% earned a bachelor's degree, and 9.6% earned graduate degrees. The basic literacy rate is approximately 99%. The United Nations assigns the United States an Education Index of 0.97, tying it for 12th in the world.

Health

The United States life expectancy of 78.3 years at birth is ranked 36th among 194 United Nations member states; while above the world average, it falls short of the overall figure in Western Europe. Increasing obesity in the United States and health improvements elsewhere have contributed to lowering the country's rank in life expectancy from 1987 to 2007, from 11th to 42nd in the world. The infant mortality rate of 6.37 per thousand places the United States 42nd out of 221 countries, above average but behind all of Western Europe. Approximately one-third of the adult population is obese and an additional third is overweight; the obesity rate, the highest in the industrialized world, has more than doubled in the last quarter-century. Obesity-related type 2 diabetes is considered epidemic by health care professionals.

The U.S. health care system far outspends any other nation's, measured in both per capita spending and percentage of GDP. The World Health Organization ranked the U.S. health care system in 2000 as first in responsiveness, but 37th in overall performance.

Health care coverage in the United States is a combination of public and private efforts, and is not universal as in all other developed countries. In 2004, private insurance paid for 36% of personal health expenditures, private out-of-pocket payments covered 15%, and federal, state, and local governments paid for 44%. In 2005, 46.6 million Americans, 15.9% of the population, were uninsured, 5.4 million more than in 2001. The main cause of this rise is the drop in the number of Americans with employer-sponsored health insurance. The subject of uninsured and underinsured Americans is a major political issue. A 2009 study estimated that lack of insurance is associated with nearly 45,000 deaths a year. In 2006, Massachusetts became the first state to mandate universal health insurance. Federal legislation passed in early 2010 will create a near-universal health insurance system around the country by 2014.

Crime and law enforcement

Law enforcement in the United States is primarily the responsibility of local police and sheriff's departments, with state police providing broader services. Federal agencies such as the Federal Bureau of Investigation (FBI) and the U.S. Marshals Service have specialized duties. At the federal level and in almost every state, jurisprudence operates on a common law system. State courts conduct most criminal trials; federal courts handle certain designated crimes as well as certain appeals from the state systems. Federal law prohibits a variety of drugs, although states sometimes pass laws in conflict with federal regulations. The smoking age is generally 18 and the drinking age is generally 21.

Among developed nations, the United States has above-average levels of violent crime and particularly high levels of gun violence and homicide. There were 5.0 murders per 100,000 persons in 2009, 10.4% fewer than in 2000. Gun ownership rights are the subject of contentious political debate.

The United States has the highest documented incarceration rate and total prison population in the world. At the start of 2008, more than 2.3 million people were incarcerated, more than one in every 100 adults. The current rate is about seven times the 1980 figure, and over three times the figure in Poland, the Organisation for Economic Co-operation and Development (OECD) country with the next highest rate. African American males are jailed at about six times the rate of white males and three times the rate of Hispanic males. The country's high rate of incarceration is largely due to sentencing and drug policies.

Though it has been abolished in most Western nations, capital punishment is sanctioned in the United States for certain federal and military crimes, and in thirty-four states. Since 1976, when the U.S. Supreme Court reinstated the death penalty after a four-year moratorium, there have been more than 1,000 executions. In 2010, the country had the fifth highest number of executions in the world, following China, Iran, North Korea, and Yemen. In 2007, New Jersey became the first state to legislatively abolish the death penalty since the 1976 Supreme Court decision, followed by New Mexico in 2009 and Illinois in 2011.

Demographics

The U.S. Census Bureau estimates the country's population now to be }}, including an estimated 11.2 million illegal immigrants. The U.S. population almost quadrupled during the 20th century, from about 76 million in 1900. The third most populous nation in the world, after China and India, the United States is the only industrialized nation in which large population increases are projected. Even with a birth rate of 13.82 per 1,000, 30% below the world average, its population growth rate is positive at 1%, significantly higher than those of many developed nations. In fiscal year 2010, over 1 million immigrants (most of whom entered through family reunification) were granted legal residence. Mexico has been the leading source of new residents for over two decades; since 1998, China, India, and the Philippines have been in the top four sending countries every year.

The United States has a very diverse population—thirty-one ancestry groups have more than one million members. White Americans are the largest racial group; German Americans, Irish Americans, and English Americans constitute three of the country's four largest ancestry groups. African Americans are the nation's largest racial minority and third largest ancestry group. Asian Americans are the country's second largest racial minority; the two largest Asian American ethnic groups are Chinese Americans and Filipino Americans. In 2010, the U.S. population included an estimated 5.2 million people with some American Indian or Alaska Native ancestry (2.9 million exclusively of such ancestry) and 1.2 million with some native Hawaiian or Pacific island ancestry (0.5 million exclusively). The census counted more than 19 million people of "Some Other Race" who were "unable to identify with any" of its five official race categories in 2010.

The population growth of Hispanic and Latino Americans (the terms are officially interchangeable) is a major demographic trend. The 50.5 million Americans of Hispanic descent are identified as sharing a distinct "ethnicity" by the Census Bureau; 64% of Hispanic Americans are of Mexican descent. Between 2000 and 2010, the country's Hispanic population increased 43% while the non-Hispanic population rose just 4.9%. Much of this growth is from immigration; as of 2007, 12.6% of the U.S. population was foreign-born, with 54% of that figure born in Latin America. Fertility is also a factor; the average Hispanic woman gives birth to 3.0 children in her lifetime, compared to 2.2 for non-Hispanic black women and 1.8 for non-Hispanic white women (below the replacement rate of 2.1). Minorities (as defined by the Census Bureau, all those beside non-Hispanic, non-multiracial whites) constitute 34% of the population, and are projected to constitute the majority by 2042.

About 82% of Americans live in urban areas (including suburbs); about half of those reside in cities with populations over 50,000. In 2008, 273 incorporated places had populations over 100,000, nine cities had more than 1 million residents, and four global cities had over 2 million (New York City, Los Angeles, Chicago, and Houston). There are fifty-two metropolitan areas with populations greater than 1 million. Of the fifty fastest-growing metro areas, forty-seven are in the West or South. The metro areas of Dallas, Houston, Atlanta, and Phoenix all grew by more than a million people between 2000 and 2008.

English is the de facto national language. Although there is no official language at the federal level, some laws—such as U.S. naturalization requirements—standardize English. In 2007, about 226 million, or 80% of the population aged five years and older, spoke only English at home. Spanish, spoken by 12% of the population at home, is the second most common language and the most widely taught second language. Some Americans advocate making English the country's official language, as it is in at least twenty-eight states. Both Hawaiian and English are official languages in Hawaii by state law.

While neither has an official language, New Mexico has laws providing for the use of both English and Spanish, as Louisiana does for English and French. Other states, such as California, mandate the publication of Spanish versions of certain government documents including court forms. Many jurisdictions with large numbers of non-English speakers produce government materials, especially voting information, in the most commonly spoken languages in those jurisdictions. Several insular territories grant official recognition to their native languages, along with English: Samoan and Chamorro are recognized by American Samoa and Guam, respectively; Carolinian and Chamorro are recognized by the Northern Mariana Islands; Spanish is an official language of Puerto Rico.

Religion

The United States is officially a secular nation; the First Amendment of the U.S. Constitution guarantees the free exercise of religion and forbids the establishment of any religious governance. In a 2002 study, 59% of Americans said that religion played a "very important role in their lives", a far higher figure than that of any other wealthy nation. According to a 2007 survey, 78.4% of adults identified themselves as Christian, down from 86.4% in 1990. Protestant denominations accounted for 51.3%, while Roman Catholicism, at 23.9%, was the largest individual denomination. The study categorizes white evangelicals, 26.3% of the population, as the country's largest religious cohort; another study estimates evangelicals of all races at 30–35%. The total reporting non-Christian religions in 2007 was 4.7%, up from 3.3% in 1990. The leading non-Christian faiths were Judaism (1.7%), Buddhism (0.7%), Islam (0.6%), Hinduism (0.4%), and Unitarian Universalism (0.3%). The survey also reported that 16.1% of Americans described themselves as agnostic, atheist, or simply having no religion, up from 8.2% in 1990.

Family structure

In 2007, 58% of Americans age 18 and over were married, 6% were widowed, 10% were divorced, and 25% had never been married. Women now mostly work outside the home and receive a majority of bachelor's degrees.

Same-sex marriage is a contentious issue. Some states permit civil unions or domestic partnerships in lieu of marriage. Since 2003, several states have legalized gay marriage as the result of judicial or legislative action. Meanwhile, the federal government and a majority of states define marriage as between a man and a woman and/or explicitly prohibit same-sex marriage. Public opinion on the issue has shifted from general opposition in the 1990s to a statistical deadlock as of 2011.

The U.S. teenage pregnancy rate, 79.8 per 1,000 women, is the highest among OECD nations. Abortion policy was left to the states until the Supreme Court legalized the practice in 1972. The issue remains highly controversial, with public opinion closely divided for many years. Many states ban public funding of the procedure and restrict late-term abortions, require parental notification for minors, and mandate a waiting period. While the abortion rate is falling, the abortion ratio of 241 per 1,000 live births and abortion rate of 15 per 1,000 women aged 15–44 remain higher than those of most Western nations.

Culture

The United States is a multicultural nation, home to a wide variety of ethnic groups, traditions, and values. Aside from the now small Native American and Native Hawaiian populations, nearly all Americans or their ancestors immigrated within the past five centuries. The culture held in common by most Americans—mainstream American culture—is a Western culture largely derived from the traditions of European immigrants with influences from many other sources, such as traditions brought by slaves from Africa. More recent immigration from Asia and especially Latin America has added to a cultural mix that has been described as both a homogenizing melting pot, and a heterogeneous salad bowl in which immigrants and their descendants retain distinctive cultural characteristics.

American culture is considered the most individualistic in the world. Though the American Dream, or the perception that Americans enjoy high social mobility, plays a key role in attracting immigrants, other developed nations offer greater social mobility. While the mainstream culture holds that the United States is a classless society, scholars identify significant differences between the country's social classes, affecting socialization, language, and values. The American middle and professional class has initiated many contemporary social trends such as modern feminism, environmentalism, and multiculturalism. Americans' self-images, social viewpoints, and cultural expectations are associated with their occupations to an unusually close degree. While Americans tend greatly to value socioeconomic achievement, being ordinary or average is generally seen as a positive attribute.

Popular media

The world's first commercial motion picture exhibition was given in New York City in 1894, using Thomas Edison's Kinetoscope. The next year saw the first commercial screening of a projected film, also in New York, and the United States was in the forefront of sound film's development in the following decades. Since the early 20th century, the U.S. film industry has largely been based in and around Hollywood, California. Director D. W. Griffith was central to the development of film grammar and Orson Welles's ''Citizen Kane'' (1941) is frequently cited as the greatest film of all time. American screen actors like John Wayne and Marilyn Monroe have become iconic figures, while producer/entrepreneur Walt Disney was a leader in both animated film and movie merchandising. The major film studios of Hollywood have produced the most commercially successful movies in history, such as ''Star Wars'' (1977) and ''Titanic'' (1997), and the products of Hollywood today dominate the global film industry.

Americans are the heaviest television viewers in the world, and the average viewing time continues to rise, reaching five hours a day in 2006. The four major broadcast networks are all commercial entities. Americans listen to radio programming, also largely commercialized, on average just over two-and-a-half hours a day. Aside from web portals and search engines, the most popular websites are Facebook, YouTube, Wikipedia, Blogger, eBay, and Craigslist.

The rhythmic and lyrical styles of African-American music have deeply influenced American music at large, distinguishing it from European traditions. Elements from folk idioms such as the blues and what is now known as old-time music were adopted and transformed into popular genres with global audiences. Jazz was developed by innovators such as Louis Armstrong and Duke Ellington early in the 20th century. Country music developed in the 1920s, and rhythm and blues in the 1940s. Elvis Presley and Chuck Berry were among the mid-1950s pioneers of rock and roll. In the 1960s, Bob Dylan emerged from the folk revival to become one of America's most celebrated songwriters and James Brown led the development of funk. More recent American creations include hip hop and house music. American pop stars such as Presley, Michael Jackson, and Madonna have become global celebrities.

Literature, philosophy, and the arts

In the 18th and early 19th centuries, American art and literature took most of its cues from Europe. Writers such as Nathaniel Hawthorne, Edgar Allan Poe, and Henry David Thoreau established a distinctive American literary voice by the middle of the 19th century. Mark Twain and poet Walt Whitman were major figures in the century's second half; Emily Dickinson, virtually unknown during her lifetime, is now recognized as an essential American poet. A work seen as capturing fundamental aspects of the national experience and character—such as Herman Melville's ''Moby-Dick'' (1851), Twain's ''The Adventures of Huckleberry Finn'' (1885), and F. Scott Fitzgerald's ''The Great Gatsby'' (1925)—may be dubbed the "Great American Novel".

Eleven U.S. citizens have won the Nobel Prize in Literature, most recently Toni Morrison in 1993. William Faulkner and Ernest Hemingway are often named among the most influential writers of the 20th century. Popular literary genres such as the Western and hardboiled crime fiction developed in the United States. The Beat Generation writers opened up new literary approaches, as have postmodernist authors such as John Barth, Thomas Pynchon, and Don DeLillo.

The transcendentalists, led by Thoreau and Ralph Waldo Emerson, established the first major American philosophical movement. After the Civil War, Charles Sanders Peirce and then William James and John Dewey were leaders in the development of pragmatism. In the 20th century, the work of W. V. Quine and Richard Rorty, built upon by Noam Chomsky, brought analytic philosophy to the fore of U.S. academics. John Rawls and Robert Nozick led a revival of political philosophy.

In the visual arts, the Hudson River School was a mid-19th-century movement in the tradition of European naturalism. The realist paintings of Thomas Eakins are now widely celebrated. The 1913 Armory Show in New York City, an exhibition of European modernist art, shocked the public and transformed the U.S. art scene. Georgia O'Keeffe, Marsden Hartley, and others experimented with new styles, displaying a highly individualistic sensibility. Major artistic movements such as the abstract expressionism of Jackson Pollock and Willem de Kooning and the pop art of Andy Warhol and Roy Lichtenstein developed largely in the United States. The tide of modernism and then postmodernism has brought fame to American architects such as Frank Lloyd Wright, Philip Johnson, and Frank Gehry. One of the first major promoters of American theater was impresario P. T. Barnum, who began operating a lower Manhattan entertainment complex in 1841. The team of Harrigan and Hart produced a series of popular musical comedies in New York starting in the late 1870s. In the 20th century, the modern musical form emerged on Broadway; the songs of musical theater composers such as Irving Berlin, Cole Porter, and Stephen Sondheim have become pop standards. Playwright Eugene O'Neill won the Nobel literature prize in 1936; other acclaimed U.S. dramatists include multiple Pulitzer Prize winners Tennessee Williams, Edward Albee, and August Wilson.

Though little known at the time, Charles Ives's work of the 1910s established him as the first major U.S. composer in the classical tradition, while experimentalists such as Henry Cowell and John Cage created a distinctive American approach to classical composition. Aaron Copland and George Gershwin developed a new synthesis of popular and classical music. Choreographers Isadora Duncan and Martha Graham helped create modern dance, while George Balanchine and Jerome Robbins were leaders in 20th century ballet. Americans have long been important in the modern artistic medium of photography, with major photographers including Alfred Stieglitz, Edward Steichen, and Ansel Adams. The newspaper comic strip and the comic book are both U.S. innovations. Superman, the quintessential comic book superhero, has become an American icon.

Food

Mainstream American cuisine is similar to that in other Western countries. Wheat is the primary cereal grain. Traditional American cuisine uses indigenous ingredients, such as turkey, venison, potatoes, sweet potatoes, corn, squash, and maple syrup, which were consumed by Native Americans and early European settlers. Slow-cooked pork and beef barbecue, crab cakes, potato chips, and chocolate chip cookies are distinctively American foods. Soul food, developed by African slaves, is popular around the South and among many African Americans elsewhere. Syncretic cuisines such as Louisiana creole, Cajun, and Tex-Mex are regionally important.

Characteristic dishes such as apple pie, fried chicken, pizza, hamburgers, and hot dogs derive from the recipes of various immigrants. French fries, Mexican dishes such as burritos and tacos, and pasta dishes freely adapted from Italian sources are widely consumed. Americans generally prefer coffee to tea. Marketing by U.S. industries is largely responsible for making orange juice and milk ubiquitous breakfast beverages.

The American fast food industry, the world's largest, pioneered the drive-through format in the 1930s. Fast food consumption has sparked health concerns. During the 1980s and 1990s, Americans' caloric intake rose 24%; frequent dining at fast food outlets is associated with what public health officials call the American "obesity epidemic". Highly sweetened soft drinks are widely popular, and sugared beverages account for 9% of American caloric intake.

Sports

Baseball has been regarded as the national sport since the late 19th century, while American football is now by several measures the most popular spectator sport. Basketball and ice hockey are the country's next two leading professional team sports. College football and basketball attract large audiences. Boxing and horse racing were once the most watched individual sports, but they have been eclipsed by golf and auto racing, particularly NASCAR. Soccer is played widely at the youth and amateur levels. Tennis and many outdoor sports are popular as well.

While most major U.S. sports have evolved out of European practices, basketball, volleyball, skateboarding, snowboarding, and cheerleading are American inventions. Lacrosse and surfing arose from Native American and Native Hawaiian activities that predate Western contact. Eight Olympic Games have taken place in the United States. The United States has won 2,301 medals at the Summer Olympic Games, more than any other country, and 253 in the Winter Olympic Games, the second most.

Measurement systems

The country retains United States customary units, constituted largely by British imperial units such as miles, yards, and degrees Fahrenheit. Distinct units include the U.S. gallon and U.S. pint volume measurements. The United States is one of only three countries that have not adopted the International System of Units. However, metric units are increasingly used in science, medicine, and many industrial fields.

William Henry "Bill" Gates III (born October 28, 1955) is an American business magnate, philanthropist, author and chairman of Microsoft, the software company he founded with Paul Allen. He is consistently ranked among the world's wealthiest people and was the wealthiest overall from 1995 to 2009, excluding 2008, when he was ranked third. During his career at Microsoft, Gates held the positions of CEO and chief software architect, and remains the largest individual shareholder, with more than 8 percent of the common stock. He has also authored or co-authored several books.

Gates is one of the best-known entrepreneurs of the personal computer revolution. Although he is admired by many, a number of industry insiders criticize his business tactics, which they consider anti-competitive, an opinion which has in some cases been upheld by the courts. In the later stages of his career, Gates has pursued a number of philanthropic endeavors, donating large amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, established in 2000.

Gates stepped down as chief executive officer of Microsoft in January 2000. He remained as chairman and created the position of chief software architect. In June 2006, Gates announced that he would be transitioning from full-time work at Microsoft to part-time work, and full-time work at the Bill & Melinda Gates Foundation. He gradually transferred his duties to Ray Ozzie, chief software architect, and Craig Mundie, chief research and strategy officer. Gates' last full-time day at Microsoft was June 27, 2008. He remains at Microsoft as non-executive chairman.

Early life

Gates was born in Seattle, Washington, to William H. Gates, Sr. and Mary Maxwell Gates, of English, German, and Scotch-Irish descent. His family was upper middle class; his father was a prominent lawyer, his mother served on the board of directors for First Interstate BancSystem and the United Way, and her father, J. W. Maxwell, was a national bank president. Gates has one elder sister, Kristi (Kristianne), and one younger sister, Libby. He was the fourth of his name in his family, but was known as William Gates III or "Trey" because his father had the "II" suffix. Early on in his life, Gates' parents had a law career in mind for him. When Gates was young, his family regularly attended a Congregational church.

At 13 he enrolled in the Lakeside School, an exclusive preparatory school. When he was in the eighth grade, the Mothers Club at the school used proceeds from Lakeside School's rummage sale to buy an Teletype Model 33 ASR terminal and a block of computer time on a General Electric (GE) computer for the school's students. Gates took an interest in programming the GE system in BASIC, and was excused from math classes to pursue his interest. He wrote his first computer program on this machine: an implementation of tic-tac-toe that allowed users to play games against the computer. Gates was fascinated by the machine and how it would always execute software code perfectly. When he reflected back on that moment, he said, "There was just something neat about the machine." After the Mothers Club donation was exhausted, he and other students sought time on systems including DEC PDP minicomputers. One of these systems was a PDP-10 belonging to Computer Center Corporation (CCC), which banned four Lakeside students—Gates, Paul Allen, Ric Weiland, and Kent Evans—for the summer after it caught them exploiting bugs in the operating system to obtain free computer time.

At the end of the ban, the four students offered to find bugs in CCC's software in exchange for computer time. Rather than use the system via Teletype, Gates went to CCC's offices and studied source code for various programs that ran on the system, including programs in FORTRAN, LISP, and machine language. The arrangement with CCC continued until 1970, when the company went out of business. The following year, Information Sciences, Inc. hired the four Lakeside students to write a payroll program in COBOL, providing them computer time and royalties. After his administrators became aware of his programming abilities, Gates wrote the school's computer program to schedule students in classes. He modified the code so that he was placed in classes with mostly female students. He later stated that "it was hard to tear myself away from a machine at which I could so unambiguously demonstrate success." At age 17, Gates formed a venture with Allen, called Traf-O-Data, to make traffic counters based on the Intel 8008 processor. In early 1973, Bill Gates served as a congressional page in the U.S. House of Representatives.

Gates graduated from Lakeside School in 1973. He scored 1590 out of 1600 on the SAT and enrolled at Harvard College in the autumn of 1973. While at Harvard, he met Steve Ballmer, who later succeeded Gates as CEO of Microsoft.

In his sophomore year, Gates devised an algorithm for pancake sorting as a solution to one of a series of unsolved problems presented in a combinatorics class by Harry Lewis, one of his professors. Gates' solution held the record as the fastest version for over thirty years; its successor is faster by only one percent. His solution was later formalized in a published paper in collaboration with Harvard computer scientist Christos Papadimitriou.

Gates did not have a definite study plan while a student at Harvard and spent a lot of time using the school's computers. Gates remained in contact with Paul Allen, joining him at Honeywell during the summer of 1974. The following year saw the release of the MITS Altair 8800 based on the Intel 8080 CPU, and Gates and Allen saw this as the opportunity to start their own computer software company. He had talked this decision over with his parents, who were supportive of him after seeing how much Gates wanted to start a company.

Microsoft

BASIC

After reading the January 1975 issue of ''Popular Electronics'' that demonstrated the Altair 8800, Gates contacted Micro Instrumentation and Telemetry Systems (MITS), the creators of the new microcomputer, to inform them that he and others were working on a BASIC interpreter for the platform. In reality, Gates and Allen did not have an Altair and had not written code for it; they merely wanted to gauge MITS's interest. MITS president Ed Roberts agreed to meet them for a demo, and over the course of a few weeks they developed an Altair emulator that ran on a minicomputer, and then the BASIC interpreter. The demonstration, held at MITS's offices in Albuquerque, was a success and resulted in a deal with MITS to distribute the interpreter as Altair BASIC. Paul Allen was hired into MITS, and Gates took a leave of absence from Harvard to work with Allen at MITS in Albuquerque in November 1975. They named their partnership "Micro-Soft" and had their first office located in Albuquerque. Within a year, the hyphen was dropped, and on November 26, 1976, the trade name "Microsoft" was registered with the Office of the Secretary of the State of New Mexico. Gates never returned to Harvard to complete his studies.

Microsoft's BASIC was popular with computer hobbyists, but Gates discovered that a pre-market copy had leaked into the community and was being widely copied and distributed. In February 1976, Gates wrote an Open Letter to Hobbyists in the MITS newsletter saying that MITS could not continue to produce, distribute, and maintain high-quality software without payment. This letter was unpopular with many computer hobbyists, but Gates persisted in his belief that software developers should be able to demand payment. Microsoft became independent of MITS in late 1976, and it continued to develop programming language software for various systems. The company moved from Albuquerque to its new home in Bellevue, Washington on January 1, 1979.

During Microsoft's early years, all employees had broad responsibility for the company's business. Gates oversaw the business details, but continued to write code as well. In the first five years, Gates personally reviewed every line of code the company shipped, and often rewrote parts of it as he saw fit.

IBM partnership

In 1980, IBM approached Microsoft to write the BASIC interpreter for its upcoming personal computer, the IBM PC. When IBM's representatives mentioned that they needed an operating system, Gates referred them to Digital Research (DRI), makers of the widely used CP/M operating system. IBM's discussions with Digital Research went poorly, and they did not reach a licensing agreement. IBM representative Jack Sams mentioned the licensing difficulties during a subsequent meeting with Gates and told him to get an acceptable operating system. A few weeks later Gates proposed using 86-DOS (QDOS), an operating system similar to CP/M that Tim Paterson of Seattle Computer Products (SCP) had made for hardware similar to the PC. Microsoft made a deal with SCP to become the exclusive licensing agent, and later the full owner, of 86-DOS. After adapting the operating system for the PC, Microsoft delivered it to IBM as PC-DOS in exchange for a one-time fee of $50,000. Gates did not offer to transfer the copyright on the operating system, because he believed that other hardware vendors would clone IBM's system. They did, and the sales of MS-DOS made Microsoft a major player in the industry.

Gates oversaw Microsoft's company restructuring on June 25, 1981, which re-incorporated the company in Washington state and made Gates President of Microsoft and the Chairman of the Board.

Windows

Microsoft launched its first retail version of Microsoft Windows on November 20, 1985, and in August, the company struck a deal with IBM to develop a separate operating system called OS/2. Although the two companies successfully developed the first version of the new system, mounting creative differences undermined the partnership. Gates distributed an internal memo on May 16, 1991, announcing that the OS/2 partnership was over and Microsoft would shift its efforts to the Windows NT kernel development.

Management style

From Microsoft's founding in 1975 until 2006, Gates had primary responsibility for the company's product strategy. He aggressively broadened the company's range of products, and wherever Microsoft achieved a dominant position he vigorously defended it. He gained a reputation for being distant to others; as early as 1981 an industry executive complained in public that "Gates is notorious for not being reachable by phone and for not returning phone calls."

As an executive, Gates met regularly with Microsoft's senior managers and program managers. Firsthand accounts of these meetings describe him as verbally combative, berating managers for perceived holes in their business strategies or proposals that placed the company's long-term interests at risk. He often interrupted presentations with such comments as, "That's the stupidest thing I've ever heard!" and, "Why don't you just give up your options and join the Peace Corps?" The target of his outburst then had to defend the proposal in detail until, hopefully, Gates was fully convinced. When subordinates appeared to be procrastinating, he was known to remark sarcastically, "I'll do it over the weekend."

Gates' role at Microsoft for most of its history was primarily a management and executive role. However, he was an active software developer in the early years, particularly on the company's programming language products. He has not officially been on a development team since working on the TRS-80 Model 100, but wrote code as late as 1989 that shipped in the company's products. On June 15, 2006, Gates announced that he would transition out of his day-to-day role over the next two years to dedicate more time to philanthropy. He divided his responsibilities between two successors, placing Ray Ozzie in charge of day-to-day management and Craig Mundie in charge of long-term product strategy.

Antitrust litigation

Many decisions that led to antitrust litigation over Microsoft's business practices have had Gates' approval. In the 1998 ''United States v. Microsoft'' case, Gates gave deposition testimony that several journalists characterized as evasive. He argued with examiner David Boies over the contextual meaning of words like "compete", "concerned" and "we". ''BusinessWeek'' reported:

}}

Gates later said he had simply resisted attempts by Boies to mischaracterize his words and actions. As to his demeanor during the deposition, he said, "Did I fence with Boies? ... I plead guilty. Whatever that penalty is should be levied against me: rudeness to Boies in the first degree." Despite Gates's denials, the judge ruled that Microsoft had committed monopolization and tying, and blocking competition, both in violation of the Sherman Antitrust Act.

Appearance in ads

Gates appeared in a series of ads to promote Microsoft in 2008. The first commercial, co-starring Jerry Seinfeld, is a 90-second talk between strangers as Seinfeld walks up on a discount shoe store (Shoe Circus) in a mall and notices Gates buying shoes inside. The salesman is trying to sell Mr. Gates shoes that are a size too big. As Gates is buying the shoes, he holds up his discount card, which uses a slightly altered version of his own mugshot of his arrest in New Mexico in 1977 for a traffic violation. As they are walking out of the mall, Seinfeld asks Gates if he has melded his mind to other developers, after getting a yes, he then asks if they are working on a way to make computers edible, again getting a yes. Some say that this is an homage to Seinfeld's own show about "nothing" (''Seinfeld''). In a second commercial in the series, Gates and Seinfeld are at the home of an average family trying to fit in with normal people.

Post-Microsoft

Since leaving Microsoft, Gates continues his philanthropy and, among other projects, purchased the video rights to the Messenger Lectures series called ''The Character of Physical Law'', given at Cornell University by Richard Feynman in 1964 and recorded by the BBC. The videos are available online to the public at Microsoft's Project Tuva.

In April 2010, Gates was invited to visit and speak at the Massachusetts Institute of Technology where he asked the students to take on the hard problems of the world in their futures.

Personal life

Gates married Melinda French on January 1, 1994. They have three children: daughter Jennifer Katharine Gates (born 1996), son Rory John Gates (born 1999), and daughter Phoebe Adele Gates (born 2002). The Gates's home is an earth-sheltered house in the side of a hill overlooking Lake Washington in Medina. According to King County public records, as of 2006 the total assessed value of the property (land and house) is $125 million, and the annual property tax is $991,000.

His estate has a swimming pool with an underwater music system, as well as a gym and a dining room.

Also among Gates' private acquisitions is the Codex Leicester, a collection of writings by Leonardo da Vinci, which Gates bought for $30.8 million at an auction in 1994. Gates is also known as an avid reader, and the ceiling of his large home library is engraved with a quotation from ''The Great Gatsby''. He also enjoys playing bridge, tennis, and golf.

Gates was number one on the Forbes 400 list from 1993 through to 2007 and number one on ''Forbes'' list of The World's Richest People from 1995 to 2007 and 2009. In 1999, Gates's wealth briefly surpassed $101 billion, causing the media to call him a "centibillionaire". Since 2000, the nominal value of his Microsoft holdings has declined due to a fall in Microsoft's stock price after the dot-com bubble burst and the multi-billion dollar donations he has made to his charitable foundations. In a May 2006 interview, Gates commented that he wished that he were not the richest man in the world because he disliked the attention it brought. Gates has several investments outside Microsoft, which in 2006 paid him a salary of $616,667 and $350,000 bonus totalling $966,667. He founded Corbis, a digital imaging company, in 1989. In 2004 he became a director of Berkshire Hathaway, the investment company headed by long-time friend Warren Buffett. In March 2010 Bill Gates was bumped down to the second wealthiest man behind Carlos Slim.

Philanthropy

Gates began to appreciate the expectations others had of him when public opinion mounted suggesting that he could give more of his wealth to charity. Gates studied the work of Andrew Carnegie and John D. Rockefeller, and in 1994 sold some of his Microsoft stock to create the William H. Gates Foundation. In 2000, Gates and his wife combined three family foundations into one to create the charitable Bill & Melinda Gates Foundation, which is the largest transparently operated charitable foundation in the world. The foundation allows benefactors access to information regarding how its money is being spent, unlike other major charitable organizations such as the Wellcome Trust. The generosity and extensive philanthropy of David Rockefeller has been credited as a major influence. Gates and his father met with Rockefeller several times, and modeled their giving in part on the Rockefeller family's philanthropic focus, namely those global problems that are ignored by governments and other organizations. As of 2007, Bill and Melinda Gates were the second-most generous philanthropists in America, having given over $28 billion to charity.

The foundation was at the same time criticized because it invests assets that it has not yet distributed with the exclusive goal of maximizing return on investment. As a result, its investments include companies that have been charged with worsening poverty in the same developing countries where the Foundation is attempting to relieve poverty. These include companies that pollute heavily, and pharmaceutical companies that do not sell into the developing world. In response to press criticism, the foundation announced in 2007 a review of its investments, to assess social responsibility. It subsequently canceled the review and stood by its policy of investing for maximum return, while using voting rights to influence company practices.

Gates's wife urged people to learn a lesson from the philanthropic efforts of the Salwen family, which had sold its home and given away half of its value, as detailed in ''The Power of Half''. Gates and his wife invited Joan Salwen to Seattle to speak about what the family had done, and on December 9, 2010, Gates, investor Warren Buffett, and Mark Zuckerberg (Facebook's CEO) signed a promise they called the "Gates-Buffet Giving Pledge", in which they promised to donate to charity at least half of their wealth over the course of time.

Recognition

In 1987, Gates was officially declared a billionaire in the pages of Forbes' 400 Richest People in America issue, just days before his 32nd birthday. As the world's youngest self-made billionaire, he was worth $1.25 billion, over $900 million more than he'd been worth the year before, when he'd debuted on the list.

''Time'' magazine named Gates one of the 100 people who most influenced the 20th century, as well as one of the 100 most influential people of 2004, 2005, and 2006. ''Time'' also collectively named Gates, his wife Melinda and U2's lead singer Bono as the 2005 Persons of the Year for their humanitarian efforts. In 2006, he was voted eighth in the list of "Heroes of our time". Gates was listed in the ''Sunday Times'' power list in 1999, named CEO of the year by ''Chief Executive Officers magazine'' in 1994, ranked number one in the "Top 50 Cyber Elite" by ''Time'' in 1998, ranked number two in the ''Upside'' Elite 100 in 1999 and was included in ''The Guardian'' as one of the "Top 100 influential people in media" in 2001.

In 1994, he was honoured as the twentieth Distinguished Fellow of the British Computer Society.

War Machine (James Rupert Rhodes) is a fictional character, a comic book superhero appearing in comic books set in the Marvel Comics universe. The character of James Rhodes first appeared in ''Iron Man'' #118 (January 1979) by David Michelinie, John Byrne and Bob Layton. The War Machine armor, which became Rhodes' signature armored battlesuit, was designed by Len Kaminski and Kevin Hopgood.

Also known by his nickname Rhodey, Rhodes has been a featured character in the ''Iron Man'' animated series, ''Iron Man: Armored Adventures'' and ''The Invincible Iron Man'' animated film. He was played by actor Terrence Howard in the 2008 film ''Iron Man'' and by Don Cheadle in the sequel ''Iron Man 2''.

Publication history

Initially a supporting character in volume one of ''Iron Man'', Rhodes later assumed the mantle of Iron Man after Tony Stark's relapse into alcoholism in issue #170 (May 1983). The character would continue in a supporting role and later resume the role of Iron Man following Stark's purported death in issue #284 (Sept. 1992). After Stark's return to the role of Iron Man, Rhodes continued as the superhero War Machine and made his solo series debut in an eponymous title after being featured as a supporting character in the superhero-team series ''Avengers West Coast''.

In addition to ''Iron Man'' and his own title ''War Machine'', Rhodes has been featured in the ensemble titles ''West Coast Avengers''; ''Force Works'' by Dan Abnett and Andy Lanning; ''Sentinel Squad O*N*E''; ''The Crew'' by Christopher Priest; and ''Avengers: The Initiative'' by Dan Slott and Christos Gage. Rhodes was also featured in the alternate-reality Marvel MAX imprint's ''U.S. War Machine'' series by Chuck Austen, and ''U.S. War Machine 2.0'', by Austen and Christian Moore.

In the series ''Iron Man: Director of S.H.I.E.L.D.'', Rhodes was featured in the storyline "War Machine: Weapon of S.H.I.E.L.D." written by Gage and artist Sean Chen. In this tie-in to the company-wide storyline "Secret Invasion", War Machine replaced Iron Man as the protagonist for the final three issues of the series. This led into a second ''War Machine'' ongoing series, written by Greg Pak with art by Leonardo Manco, which lasted 12 issues. Featured in the ensemble title ''Secret Avengers'', War Machine is the lead character of the series ''Iron Man 2.0'' by writer Nick Spencer and artist Barry Kitson.

Fictional character biography

Origins

James Rupert Rhodes, an African-American from the South Philadelphia section of Philadelphia, Pennsylvania, was a lieutenant colonel in the United States Air Force who served tours of duty in Southeast Asia. A combat pilot, he was stranded in the jungle behind enemy lines after his helicopter was shot down by Viet Cong rocket fire. He encounters Iron Man, who escaped from Wong-Chu's prison camp in his prototype suit of powered armor, for the first time. Defeating the Viet Cong soldiers that ambushed them, Rhodes and Iron Man discovered an enemy rocket base that was the origin of the rocket fire that grounded Rhodes in the first place. Destroying the base with a stolen Viet Cong helicopter, Rhodes and Iron Man flew the helicopter back to the American defense perimeter. At the base hospital in Saigon, Stark arrives in person to thank Rhodes for helping Iron Man and to offer Rhodes a job as his personal pilot. After the Vietnam War was over and after taking several career paths including mercenary work, Rhodes finally took Stark's offer and became Stark's personal pilot, chief aviation engineer for Stark International, and one of Stark's closest friends.

The all new Iron Man

Due to Obadiah Stane's actions, Stark International was losing foreign contracts and going into heavy debt. With Stark's company and personal life in disarray, Stark relapsed into alcoholism. After an intoxicated Stark was defeated by Magma, Rhodes donned the Iron Man armor for the first time and defeated Magma. Stark asked Rhodes to be Iron Man while Stark continued his life of alcoholism. Rhodes, along with scientist Morley Erwin, quits Stark International and sent the remaining Iron Man armors into the ocean to protect Stark’s technology from Stane and S.H.I.E.L.D., who monitored the Stane takeover. Morley Erwin maintained the Iron Man armor and served as Rhodes’ technical support while Rhodes fought villains such as the Mandarin, Thunderball, the Zodiac, and the Radioactive Man as Iron Man. He became a charter member of the West Coast Avengers and fought in the Beyonder's "Secret Wars". Rhodes, Morley Erwin, and Morley's sister Dr. Clytemnestra Erwin planned to create a new electronics firm based in California. Rhodes took mercenary jobs to provide money for the armor's upkeep and to fund the company. Recovering from his alcoholism, Tony Stark joined the three and they formed the company Circuits Maximus. Due to the armor’s helmet being tailored to Stark’s brainwaves, Rhodes developed headaches and grew more erratic and aggressive. Stark helped Rhodes maintain the armor, but Rhodes' paranoia and hatred made him believe that Stark wanted to retake the armor. During a battle with Vibro, Rhodes went on a rampage to capture the villain and Stark was forced to wear his new testbed armor (resembling Stark's first Iron Man armor) to stop Rhodes and talk him out of his rage.

Rhodes sought help from Dr. Henry Pym to cure his headaches while Stark delivered Rhodes’ resignation to the Avengers and revealed his identity to Hawkeye and Mockingbird. Pym sent Rhodes to Dr. Michael Twoyoungmen (Shaman of Alpha Flight) and Rhodes cured himself of his headaches via a journey through a mystic dimension called "The Gorge" that revealed Rhodes’ guilt of feeling unworthy of the armor. While Rhodes was finally at peace and left his armor behind in the dimension, the armor was empowered by The Omnos, a being of extra-dimensional energy, and was returned to Rhodes. Rhodes resumed operating as Iron Man with Stark using his own testbed armor to assist Rhodes. Due to a bomb sent by Stane to Circuits Maximus that injured Rhodes and killed Morley Erwin, Stark became active as Iron Man again, donning his newly-completed "Silver Centurion" model, and defeated Stane.

Out of the armor

Rhodes remained at Stark's side as Stark regained his personal fortune and built a new corporation, Stark Enterprises, remaining in California. Rhodes donned the red-and-gold armor once more when A.I.M. attacked the under-construction Stark space station. However, the armor's seals had been damaged in a shuttle explosion, causing Rhodes to suffer severe burns upon reentry; he survived only by Stark using his own armor as a heat shield to minimize Rhodes' exposure. After Rhodes recovered, he continued to play a key role in assisting Stark, particularly during the first ''Armor Wars'' storyline.

When Stark was shot by Kathy Dare and left paralyzed, he needed a fill-in for the role of Iron Man. Rhodes refused, citing the history between him and the armor, "not all of it good". Stark would call upon the former Force, Clay Wilson (known as Carl Walker at this point), to fill in, wearing the modified Stealth armor, until Stark could modify his regular armor to allow him to function normally inside the suit. Rhodes would reluctantly return to the armor to fight the Mandarin at the behest of the Chinese government, in order to allow Stark to seek medical assistance in their country. In the end, Stark (using a remote-control set of armor) and Rhodes team up with the Mandarin to stop the larger threat of the Makulan dragons.

Iron Man once again and the birth of War Machine

The Masters Of Silence, three Japanese warriors tricked by Justin Hammer into attacking Iron Man, defeated Stark with technology that enabled them to not be affected by repulsors or unibeams. To combat the threat, Stark designed the "Variable Threat Response Battle Suit, Model XVI, Mark I" (nicknamed "War Machine"), a more heavily armed version of the Iron Man armor designed for all-out warfare. After Stark's apparent death in the comic book, he left Rhodes in control of Stark Enterprises as its new CEO, along with a new Variable Threat Response Battle Suit designed especially for Rhodes to continue the Iron Man legacy. As Iron Man once again, Rhodes used the armor and fought against threats such as the Living Laser, the second Spymaster, Blacklash, the Beetle, and Atom Smasher.

Upon the revelation that Stark was alive, Rhodes quit Stark Enterprises and the friendship between the two was fractured. After teaming with Iron Man against battledroids programmed to kill Rhodes, Stark wanted Rhodes to keep the Variable Threat Response Battle Suit stating that the armor always belonged to Rhodes. Rhodes eventually kept the armor and later adopted the name of War Machine. When the robot Ultimo went on a rampage, Rhodes called together Harold "Happy" Hogan, Bethany Cabe, Eddie March, "Carl Walker" and Michael O'Brien to pilot various Iron Man armors to take down Ultimo as the Iron Legion. He rejoined the West Coast Avengers as War Machine and served with the team until he resigned after an argument with Iron Man during an Avengers team meeting. During the beginning of the ''War Machine'' series, Rhodes was approached by Vincent Cetewayo, noted activist from the African country of Imaya and founder of the human rights organization Worldwatch Incorporated. Cetewayo offered Rhodes the position of Worldwatch's Executive Director, but the offer was declined. Cetewayo was kidnapped by Imayan forces led by the dictator President Eda Arul. Receiving no aid from S.H.I.E.L.D. or the Avengers, Rhodes traveled to Imaya as War Machine to free Cetewayo. Joined by Deathlok, the two evaded capture from a S.H.I.E.L.D. unit led by Major Bathsheva "Sheva" Joseph and joined the fight to liberate Imaya. Rhodes successfully led Imayan rebels into combat against Arul's forces, but failed to save Cetewayo from being killed by the Advisor, the apparent mastermind of Arul's rise to power. Shaken by the death of Cetewayo and finding something worth fighting for, Rhodes takes the position of Worldwatch's Executive Director and hired Sheva Joseph, who left S.H.I.E.L.D. after her assignment in Imaya.

During the ''Hands of the Mandarin'' crossover, Stark disapproved of the actions of War Machine in Imaya and demanded that Rhodes relinquish the armor when he returned to Stark Enterprises to get the specifications for his armor. The two men battled each other until the fight was stopped by Bethany Cabe, the Head Of Security for Stark Enterprises. While their armor was rebooting, the Mandarin captured Rhodes and Stark, discovering their identities. Century of the superhero team Force Works rescued Rhodes, but his armor was useless thanks to the Mandarin’s anti-technology field. Rhodes and Stark reconciled and joined with Force Works to stop the Mandarin and his Avatars from using the Heart Of Darkness for their plans of conquest. Stark gave Rhodes the blueprints to the War Machine armor and a fully upgraded armor with new armaments was made. Rhodes continued to use the War Machine armor in a solo superhero career, occasionally fighting alongside Stark and Force Works.

The Warwear

After the events of the ''Time War'' storyline, in which Rhodes teamed up with Captain America, Bucky and Sgt. Nick Fury & his Howling Commandos to stop Neo-Nazis from sending modern weaponry to Nazi Germany, the War Machine armor was lost in the time stream. Rhodes returned to civilian life, but he ended up acquiring a brand new alien armor known as the Eidolon Warwear after meeting a mysterious woman named Skye and fighting an alien known as a Lictor. Skye was sent to teach Rhodes to use the Warwear and revealed that Rhodes was chosen to fight against Stark (who was under the control of Immortus disguised as Kang the Conqueror). Skye was fatally wounded by Dirge, another Eidolon Warrior sent by Immortus, and Rhodes defeated him in combat. Stark eventually breaks free of Immortus' control and sacrificed his life while Rhodes foiled Immortus' plot by using Dirge's Warwear to destroy the Starcore satellite armed with a chronographic weapon. S.H.I.E.L.D. was made aware of Rhodes' alien armor and hunted him down, but Rhodes evaded capture. To protect Worldwatch, he resigns as Executive Director.

In ''Tales of the Marvel Universe'', Rhodes rejoined Stark Enterprises to protect his friend's legacy while the Japanese company Fujikawa Industries bought out Stark Enterprises. Rhodes was kept around to help with the transition to Stark-Fujikawa. He was offered the job of President Of Corporate Liaison Operations, but kept away from Fujikawa's attempt to discover the secrets to Stark's Iron Man armor technology contained in a single gauntlet. Rhodes infiltrated the security system at Stark-Fujikawa's Research and Development facility, recovered the gauntlet, and purged the Fujikawa database of all Iron Man armor technology data by downloading the Eidolon Warwear directly into the Fujikawa computers to attack the system. Losing the armor as a result of the sabotage mission, Rhodes quits Stark-Fujikawa. After serving as one of Stark's trustees when Iron Man was presumed dead after the final battle with Onslaught, Rhodes starts his own marine salvage business called "Rhodes Recovery" and retires from superheroics.

Post War Machine

Despite staying in retirement and focusing on his salvaging company, Rhodes assisted Stark on occasion. In volume three of ''Iron Man'', He helped Stark defeat freelance mercenary and arms dealer Parnell Jacobs, who was masquerading as a villainous War Machine. A former friend and mercenary partner of Rhodes, Jacobs was under the employ of Sunset Bain and piloted a version of the War Machine armor based on armor parts that Jacobs found from the discarded original and reverse engineering by Stuart Clarke.

Due to mismanagement by his accountant and an extravagant lifestyle, Rhodes is left with depleted funds and files for bankruptcy. He is informed by the New York Police Department that his sister Jeanette "Star" Rhodes was killed in a notorious section of Brooklyn overridden with crime and drugs known as "Little Mogadishu". During a fight with some local thugs, he is helped by Josiah el Hajj Saddiq a.k.a. Josiah X, a local minister who is the son of the black Captain America. Josiah X helped Rhodes obtain footage of Jeanette's killers. With the police unable to apprehend, Rhodes captured his sister's murderers with NYPD narcotics officer Kevin "Kasper" Cole making the arrests. He discovers that the criminals that killed Jeanette were drug dealers working for the 66 Bridges, a powerful street gang with a big percentage of East Coast criminal operations. Rhodes unknowingly invested in the 66’s front company Grace & Tumbalt, a black-owned corporation that created Little Mogadishu due to their gentrification efforts. During his campaign against the 66 Bridges, Rhodes crosses paths with Cole, who secretly fights crime as The White Tiger in order to gain arrests for a promotion to detective, and Danny Vincent (Manuel Vincente), an ex-spy known as Junta with allegiance only to himself. Joining forces with these two men along with Josiah X as Justice, Rhodes and The Crew took on the 66 Bridges gang and their CEO Nigel "Triage" Blacque.

Rhodes later becomes a key member of the Office of National Emergency (O*N*E) and the head combat instructor for Sentinel Squad O*N*E. He began developing doubts about the nature of his job, such as being ordered to arrest the Black Panther and Storm when they refused to sign SHRA.

Return

When Rhodes served as a military consultant at a base in Dubai, a terrorist attack left Rhodes severely injured. Stark arrived in Dubai and rebuilt him with new limbs, bionics, and cybernetics. Rhodes once again becomes War Machine and was made field commander and a director of Camp Hammond to help train SHRA registered recruits of the Fifty State Initiative program. When the Skrulls invaded earth and unleashed a virus that disabled all Starktech systems along with Rhodes' life-support systems, he is forced to rely on Baron Von Blitzschlag's electrical powers to keep him alive while managing to activate a cluster of emergency generators in his armor that incorporated Stanetech parts in its design.

In the ''War Machine: Weapon Of S.H.I.E.L.D.'' storyline, Rhodes received a secret holographic message with coordinates after the global Starktech failure. Despite an intercepting Skrull fleet, Rhodes found a secret cloaked satellite in outer space with Suzanne "Suzi" Endo at the satellite ahead of him. Endo was there to help because of her background in cybernetics and Rhodes viewed another message from Stark revealing that Rhodes' armor, as well as the satellite, was independent from all Earth systems with Rhodes himself as a part of Stark's contingency plan. A Skrull fleet followed Rhodes to the satellite and Endo revealed that the satellite is a functional weapon with Rhodes being the key to its activation. With the satellite linked to Rhodes, it transformed into a giant "War Machine" robotic form. Destroying the Skrull fleet, he left the satellite to Russian airspace to destroy an escaping Skull ship. He made his way to a weapons depot in Tatischevo where the Winter Guard was protecting the nuclear weapons from the Skrulls. The Winter Guard ordered him to leave under the orders of the Russian military, but Rhodes ignored and was captured on a Skrull warship. He escaped and with Endo's help, used the warship to destroy the Skull fleet with the Winter Guard disobeying orders so that they could aid Rhodes. The last Super-Skrull attempted to detonate the nuclear warheads by turning himself into energy, but Rhodes used his armor's capabilities to absorb the energy.

Dark Reign

In ''Dark Reign: New Nation'', Rhodes faced Anton Aubuisson, a corrupt former French soldier with the Roxxon Energy Corporation in negotiations with the Anunquit tribe in western Canada. Rhodes defeated Aubuisson and discovered the use of Ultimo technology given to Aubuisson by Eaglestar International, a corrupt paramilitary defense contracting firm. This led to Rhodes traveling to Santo Marco and finding Parnell Jacobs, once believed to be killed by Stuart Clarke,. Rhodes recruits Jacobs to be his "one-man pit crew" to stop Eaglestar's efforts after informing him that Jacobs' estranged wife Dr. Glenda Sandoval, a medic with Eaglestar, was in forced imprisonment. In a side story, a team under the direction of Bethany Cabe developed a clone body for Rhodes to take over. The team's facility was attacked and the clone body was taken by Norman Osborn. Rhodes, with support from Jacobs and Cabe, invades the Eaglestar headquarters in the nation of Aqiria. Rescuing Sandoval and dealing with threats such as the Dark Avenger Ares and civilians infected with Ultimo technology, Rhodes deduced that the Ultimo technology came from the United States where Ultimo was last seen. Rhodes took on the mission of destroying the Ultimo components with Sandoval, Cabe, Jacobs, former S.H.I.E.L.D. agent Jake Oh, and a returning Suzi Endo as "Team War Machine". The team faced the threat of Ultimo in the form of Morgan Stark, Tony Stark's cousin, with the help of Rhodes' former West Coast Avengers teammates and Norman Osborn in a temporary alliance. While Rhodes was captured after ruining Osborn's plan to make Ultimo his weapon, his team exposed the "Bainesville Ten", a group of high ranking officials and industry captains responsible for worldwide crimes. Despite Osborn's efforts to distract from the indictment of the group by putting Rhodes on trial at The Hague for war crimes, Rhodes and his team foiled Osborn's scheme with Rhodes himself transferred to his clone body after saving the life of a child.

In the "Stark Disassembled" storyline, Rhodes went to Broxton, Oklahoma where Tony Stark was left in a persistent vegetative state. Following recorded instructions from Stark, Rhodes extracted wires from Pepper Potts' Rescue suit and connected Captain America's shield to the implant on Stark's chest, which would be started by Thor's lightning, in order to reboot Stark's brain.

Heroic Age

After the ''Siege'' storyline, War Machine joined the new Secret Avengers team, alongside Beast, Nova, Steve Rogers, Valkyrie, and Moon Knight.

Due to a government contract between Tony Stark's "Stark Resilent" company and The Pentagon, War Machine was assigned a new position as the US military's own "Iron Man". Now at the rank of Lieutenant Colonel, Rhodes is under the command of General Babbage, who has a personal grudge against Rhodes for his actions when he battled Ultimo and Norman Osborn in the previous ''War Machine'' series. His first assignment was to track down Palmer Addley, a former weapons designer for DARPA, the Defense Advanced Research Projects Agency. Addley is committing terrorist acts around the world, despite having been dead for months. When War Machine confronts the alleged dead man, Addley's response is to drop a nuclear weapon on him. Rhodes survives, but this prompts Tony Stark to replace his armor with a far more advanced model: the "Iron Man 2.0" armor.

During the ''Fear Itself'' storyline, War Machine is seen in Washington DC helping Ant-Man and Beast. War Machine learns from the Prince of Orphans that the "Eighth City" has been opened.

Powers and abilities

Skills

Rhodes was trained as an aircraft pilot and studied aviation engineering while in service with the United States Marine Corps. He is knowledgeable in aircraft operation/maintenance and has piloted various aircraft at Stark Enterprises. Rhodes is an experienced soldier trained in unarmed combat and military weaponry such as small arms. In addition to being a pilot, engineer, soldier, and businessman, Rhodes derives multiple abilities from various hi-tech armors, either designed by Stark Industries or extraterrestrial in nature. With his years of experience with both the Iron Man and War Machine powered armors, Rhodes is skilled in armored combat and uses a more physical fighting style compared to Stark.

Armors

Iron Man Armor V

First Appearance: ''Iron Man'' #85 (April 1976)

Rhodes' first armor as Iron Man was a solar charged carbon-composite based steel mesh armor which provided him with superhuman-level strength and durability. It was armed with repulsors in each palm of the armor's gauntlets and a multifunctional unibeam projector in the chest.

War Machine Armor (Variable Threat Response Battle Suit Mark II, Model JRXL-1000)

First Appearance: ''Iron Man'' #284 (September 1992)

The original Variable Threat Response Battle Suit Mark I was a version of the Iron Man armor utilizing laser guided munitions. Stark gave Rhodes a modified version of the armor, Mark II Model JRXL-1000, created just for him with the inclusion of repulsors and a unibeam projector. The armor could be modified with various modular weapons and has an improved tactical computer system with automatic targeting. Additional weapons included pulse bolt generators, retractable shoulder minigun, variable-configured double-barrel cannons on each gauntlet, gauntlet mounted flamethrower, plasma blade on the left gauntlet, missile box launcher, micro-rocket launcher, particle beam discharger, and an electromagnetic pulse generator in the unibeam projector that could shut down any electronic device in a 50-mile radius. The armor also included a photon emitter that created a force shield, forcefield-based stealth technology, boot-jet propulsion, and a self-contained breathing system.

The second version of the armor, reconfigured by Stark, contained upgraded improvements such as heat seeking missile launchers, pulse cannon, and retractable weapon pods located on its back. Rhodes utilized different types of specialty ammunition as well as non-lethal weapons such as rubber bullets. Though Rhodes lost the original armor, he still possessed a functional prototype helmet and gauntlet.

Eidolon Warwear

First Appearance: ''War Machine'' #18 (September 1995)

The armor is a symbiotic bio-armor system of alien origin and provided Rhodes with superhuman strength, durability, and speed. The armor responded to Rhodes' commands and created weapons based on his thoughts and needs. When inactive, it was concealed inside a "mandala" or tattoo-like mark on Rhodes' chest. The left arm is capable of firing destructive energy blasts while the right arm is able to morph into a blade. The armor can "unskin" remote drones that are capable of feats such as discharging various types of energy, infiltrating electronic/computer systems, creating energy fields, and completing basic tasks. If the drone are destroyed, Rhodes feels pain due to the symbiotic connection. The armor can morph into a "full battle mode," which provided unspecified enhancement to both the armor and Rhodes himself. It was also capable of space travel with an unlimited life support system. During battle, the armor would have the strange ability to "sing" alien war songs.

Sentinel Squad Armor

First Appearance: ''Sentinel Squad O.N.E.'' #1 (March 2006)

During the ''Sentinel Squad O*N*E'' series, he used an armor that was similar to the design of previous Iron Man powered armors and was based on the primary Sentinel piloted armors that the squad used in combat. The armor was derived of S.H.I.E.L.D. technology and Stark-designed upgrades. Rhodes also piloted a larger advanced Sentinel model codenamed "War Machine". The armors were constructed of a unique mix of steel and fiberglass and contained many offensive and defensive improvements in weaponry and enhancements.

Stanetech Based War Machine Armor

First Appearance: ''Avengers: The Initiative'' #1 (March 2007)

Used during ''Avengers: The Initiative'' to volume two of ''War Machine'', this version of the War Machine armor shows all the abilities of the previous iterations with bleeding edge military ballistics and weaponry. Unlike previous War Machine armors, the armor incorporated advanced components derived from Obadiah Stane's reverse engineering of older Iron Man armor that made him immune to any Starktech based systems attack. Rhodes' bionics required an added life support system with cybernetic implants linked to the armor's systems. The armor is composed of alloys such as titanium and Wakandan vibranium, coated for stealth capabilities, and capable of space and underwater travel. Armaments included sonic generators, pulse bolts, a minigun, and a retractable unibeam projector. The armor can interface with any system and has interlocking capabilities that integrated mechanical constructs to repair and upgrade the armor. During the second ''War Machine'' series, Rhodes used this ability to merge with jet fighters and tanks deliberately to gain their technology and weapons. At the end of the series, Rhodes (Now in a cloned version of his body) is seen wearing a non-cybernetic version of the armor.

War Machine Armor V

First Appearance: ''Secret Avengers'' #1 (May 2010)

Used during issues of ''Secret Avengers'' and appearances in other comic series, this upgraded incarnation of the Variable Threat Response Battle Suit has a similar design to the movie version of the War Machine armor with armaments similar to previous incarnations such as a retractable shoulder minigun, repulsor technology, and shoulder missile launcher. The armor was destroyed by a nuclear attack in the first arc of the series ''Iron Man 2.0''.

"Iron Man 2.0" War Machine Armor

First Appearance: ''Iron Man 2.0'' #3 (April 2011)

Created in the series ''Iron Man 2.0'' by Tony Stark, this War Machine armor is a complete redesign after the destruction of the previous model. Designed by ''Iron Man 2.0'' artist Barry Kitson, the armor emphasizes stealth, recon, infiltration, and combat readiness. Unlike its predecessors, it is a slimmed down armor with no visible external weaponry such as shoulder miniguns or missile launchers. The armor's color scheme is gunmetal with black detailing and has two lines on the helmet's left eye area that glows according to the repulsor reactor's color. The armor utilizes upgraded technology such as an updated Chameleon Mode (previously a feature of the "Silver Centurion" Iron Man armor) for optical invisibility, holographic projection, and camouflage purposes. The armor also possesses Ghost technology to phase through solid objects, scanner invisibility to become undetectable to all targeting systems, and a Combat Mode that can deploy weaponry which is normally hidden and increase the size and bulk of the armor. But the armor has limitations such as strain of the armor's repulsor reactor, disorientation from the Chameleon Mode, and the inability to be both invisible and intangible at the same time due to a compatibility issue.

Other versions

1602

In ''Marvel 1602: New World'', there is a character named Rhodes, a Moor who is the engineer of the armor worn by the Spanish nobleman Lord Iron. Rhodes accompanied Lord Iron to the New World and assists in Lord Iron's mission to hunt down David Banner, former advisor to King James I of England and the man who tortured Lord Iron when he was captured by the British.

Amalgam Comics

In the Amalgam Comics Universe created by Marvel Comics and DC Comics, there is a character named Stewart Rhodes that appears in the comic ''Iron Lantern'' #1. A pilot and engineer employed at Stark Aircraft, he knows the secret of Hal Stark's double life as Iron Lantern. Stewart Rhodes is the amalgam of James Rhodes and John Stewart.

Marvel Zombies

In ''Marvel Zombies: Dead Days'', War Machine is seen amongst the crowd of heroes who have survived the Zombie plague so far. His fate is not depicted.

In ''Marvel Zombies Return'', Zombie Giant Man finds a way to enter parallel universes and invades a universe that resembles the time period in which Tony Stark was an alcoholic. Giant Man infected the parallel universe's Happy Hogan, Pepper Potts and a number of people at Stark Industries. The James Rhodes from the parallel universe finds the Iron Man armor located in a bathroom and puts it on to reach Stark. After Stark sacrifices himself to kill as many zombies as possible, Rhodes takes the name Iron Man and announces he will help the police fend off the zombies. He also becomes a member of this reality's Illuminati. Years later, Rhodes joins the New Avengers in a heavily armed suit reminiscent of the War Machine armor but in the Iron Man color scheme. This Rhodes is at least partly cybernetic, having escaped falling victim to the zombie virus himself by cutting off his limbs after being bitten in order to protect himself from the virus, the armor consisting at least partly of cybernetic limbs rather than a simple suit. The Avengers team assembled consists of Iron Man and the zombified Spider-Man, Hulk and Wolverine. Rhodes sacrifices one of his last three fingers to lure the Zombie Avengers to the Savage land. Then, using a nanite virus developed by Spider-Man, the team defeats the zombie Avengers, eradicating the zombie menace.

MC2

In the MC2 alternate future, Rhodes gained superhuman powers after exposing himself to experimental microscopic robots. While Tony Stark had intended to test them on himself, Rhodes did not feel it would be right for Stark to unnecessarily risk his life. Although now blessed with exponentially-increasing invulnerability and an impressive array of energy-based attacks, the nanites slowly corrupt Rhodes' mind, eventually destroying his personality and leaving him as little more than a very powerful, humanoid robot. He eventually works as a personal bodyguard for Tony Stark, and although he adopts a superhero uniform (vaguely reminiscent of Superman, though with a different color scheme and no chest insignia) neither he nor Stark bother to come up with a moniker for him. Spider-Girl refers to him as "Fred" for most of her series, for simple lack of anything else to call him.

U.S. War Machine

In the alternate-reality MAX imprint series ''U.S. War Machine'', Tony Stark announces he is retiring from developing weapons after he and his bodyguard James Rhodes, who had piloted the MPI-2100 Mobile Infantry Suit a.k.a. the "War Machine" armor, had used lethal force in the defeat of foreign tyrant Doctor Doom's armies. He stated he was mothballing the War Machine armor and presented the SI1-211 "Iron Man" as his new bodyguard. Rhodes, however, uses the War Machine armor to fight rogue agents of the terrorist group Advanced Idea Mechanics, and after killing two of them is fired by Stark. Afterward, former War Machine pilot Parnell Jacobs attacks Rhodes at home in an attempt to steal the War Machine armor. After Rhodes defeats Jacobs, Colonel Nick Fury, head of the espionage agency S.H.I.E.L.D., has Rhodes and Jacobs brought in to the agency's headquarters, the Skycarrier.

Jacobs reveals that his wife, Glenda Sandoval, was taken hostage by A.I.M., with the promise of release if Jacobs delivered the original War Machine armor. But Jacobs had sold that armor to another terrorist group, HYDRA, to gain money when he learned his wife was pregnant. S.H.I.E.L.D. retrieves the armor from HYDRA and, with the guidance of 12-year-old-genius armament designer "Scotch", reverse-engineers its technology to create its own version of the War Machine armor for a planned Special Operations division, dubbed "U.S. War Machine", with Rhodes in charge. Targeting A.I.M., the team includes Jacobs, Dum Dum Dugan, and Sheva Josephs.

In the sequel series ''U.S. War Machine 2.0.'', Stark is furious that S.H.I.E.L.D.'s U.S. War Machine division exists and combats it as Iron Man accompanied by his own armored forces—Happy Hogan, Bethany Cabe, and Eddie March—in MPI-2100 Mobile Infantry Suits. Rhodes, now a major, and his division team with Captain America (James "Bucky" Barnes), Sam Wilson, and Clint Barton, to stop Doctor Doom from detonating stolen nuclear weapons planted on the Millennium Wheel in London.

Ultimate Marvel

James Rhodes first appears as a prep school student and the victim of frequent bullying at the school due to his ethnicity, that he comes from a poorer family and the fact that he's there because of the school's racial quota. He finds an unlikely friend in a young Tony Stark who defends him against the bullies - much to his dismay because it only serves to attract more attention to himself and, thus, increase his torment. Stark is keen on Rhodes being his friend, while Rhodes, initially, is uneasy about Stark and his burgeoning friendship. Later, after Stark is severely attacked at school and is aided by Rhodes (which turns out to be a peripheral attack on Stark's father), both leave the school and with Stark's father's help, are accepted into the Baxter Building's School for Exceptional Children along with Rhodes's sister, one, because they are all strikingly intelligent, but also for their own protection. Both begin work on different projects and eventually, Stark takes Rhodes into his confidence and allows Rhodes a chance to wear and help design some of the armor he and his father have innovated. Rhodes and Stark's friendship strengthens and Rhodes is later seen making another armor version named "War Machine" which he is going to trade with Stark's "Iron Man" armor when both are fully developed. A couple of years later, Stark and Rhodes, in their respective armor, team up as fake "Robots" to take out a terrorist group for the government. This origin, however, was retconned as being a fictionalized history of Tony Stark's early years. Years later, Rhodes, now a Colonel, is seen sporting a new War Machine armor created by Tony Stark's older brother Gregory Stark of which both are, for some reason, now estranged, which he uses to save two abducted U.S. army officers from the hands of the Taliban. Once the officers had been secured, Rhodes decides to kill the unarmed civils and the enemy after they surrendered, giving the first glimpse into a more ruthless, apathetic and even sadistic War Machine; a far cry from earlier views of Rhodes. Later, in France, he attempts to capture a seemingly rogue Captain America as part of the reactivated "Project Avengers" with new armor that is quite larger, is bloated with numerous ballistic weapons (far more than Tony Stark's Iron Man armor), and can also, evidently, even transform into a German sports car. Rhodes is almost able to capture Captain America, but their last confrontation involves Cap being in a room full of school children. Rhodes' ruthlessness is shown ever further as he contemplates continuing his attack, until Cap reminds him that any "Collateral Damage" involving school children would be a Public Relations and Political nightmare prompting War Machine to back off, but for all the wrong reasons. At this point, Rhodes' new mental, emotional or combat attitude has not been addressed or explained.
