Contemporary era

The leadership role taken by the United States and its allies in the UN–sanctioned Gulf War, under President George H. W. Bush, and the Yugoslav wars, under President Bill Clinton, helped to preserve its position as a superpower. The longest economic expansion in modern U.S. history—from March 1991 to March 2001—encompassed the 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 U.S. 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 a "War on Terrorism". In late 2001, U.S. forces led an invasion of Afghanistan, 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. Lacking the support of NATO or an explicit UN mandate for military intervention, Bush organized a Coalition of the Willing; coalition forces preemptively invaded Iraq in 2003, removing dictator and former U.S. ally Saddam Hussein. Amnesty International has accused the United States of human rights violations in its pursuit of the War on Terrorism and the Iraq War.In 2005, Hurricane Katrina caused severe destruction along much of the Gulf Coast, devastating New Orleans. On November 4, 2008, amid a global economic recession, Barack Obama was elected president. He is the first African American to hold the office.

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. Most of the rest have been carved from territory 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. Another set of exceptions comprises those states created out of the territory of the original thirteen. Early in the country's history, three states were created in this manner: Kentucky from Virginia; Tennessee from North Carolina; and Maine from Massachusetts. 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 territories (except for American Samoa) possess U.S. citizenship.

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. Almost all countries have embassies in Washington, D.C., and many host consulates around the country. Likewise, nearly all nations host American diplomatic missions. However, Cuba, Iran, North Korea, Bhutan, Sudan, and the Republic of China (Taiwan) do not have formal diplomatic relations with the United States.

The United States enjoys a special relationship with the United Kingdom and strong ties with Australia, New Zealand, Japan, Israel, and fellow NATO members. It also works closely 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 2005, the United States spent $27 billion on official development assistance, the most in the world. However, as a share of gross national income (GNI), the U.S. contribution of 0.22% ranked twentieth of twenty-two donor states. Nongovernmental sources such as private foundations, corporations, and educational and religious institutions donated $96 billion. The combined total of $123 billion is also the most in the world and seventh as a percentage of GNI.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 2005, the military had 1.38 million personnel on active duty,along with several hundred thousand each in the Reserves and the National Guard for a total of 2.3 million troops. The Department of Defense also employs 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 and aerial refueling tankers, the Navy's fleet of eleven active aircraft carriers, and Marine Expeditionary Units at sea in the Navy's Atlantic and Pacific fleets. Outside of the United States, the military is deployed to 770 bases and facilities, on every continent except Antarctica. 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 2006, over $528 billion, was 46% of global military spending and greater than the next fourteen largest national military expenditures combined. (In purchasing power parity terms, it was larger than the next six such expenditures combined.) The per capita spending of $1,756 was about ten times the world average. At 4.06% of GDP, U.S. military spending is ranked 27th out of 172 nations. The proposed base Department of Defense budget for 2009, $515.4 billion, is a 7% increase over 2008 and a nearly 74% increase over 2001. The cost of the Iraq War to the United States has been estimated to reach $2.7 trillion. As of May 3, 2009, the United States had suffered 4,284 military fatalities during the war and over 31,000 wounded.

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 $14.3 trillion constitutes 23% of the gross world product at market exchange rates and almost 21% of the gross world product at purchasing power parity (PPP). The largest national GDP in the world, it was about 4% less than the combined GDP of the European Union at PPP in 2007. The country ranks seventeenth in the world in nominal GDP per capita and sixth in GDP per capita at PPP.The United States is the largest importer of goods and third largest exporter, though exports per capita are relatively low. Canada, China, Mexico, Japan, and Germany are its top trading partners.The leading export commodity is electrical machinery, while vehicles constitute the leading import.The United States tops the overall ranking in the Global Competitiveness Report. After an expansion that lasted just over six years, the U.S. economy has been in recession since December 2007.

Demographics

The United States population is projected by the U.S. Census Bureau to be 306,414,000,including an estimated 11.2 million illegal immigrants.The United States is the third most populous nation in the world, after China and India. Its population growth rate is 0.89%,compared to the European Union's 0.16%. The birth rate of 14.16 per 1,000, 30% below the world average, is higher than any European country's except Albania and Ireland. In fiscal year 2008, 1.1 million immigrants 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 is the only industrialized nation in which large population increases are projected.

The United States has a very diverse population—thirty-one ancestry groups have more than a million members. White Americans are the largest racial group, with German Americans, Irish Americans, and English Americans constituting three of the country's four largest ancestry groups. African Americans are the nation's largest racial minorityand third largest ancestry group. Asian Americans are the country's second largest racial minority; the two largest Asian American ancestry groups are Chinese andFilipino.In 2007, the U.S. population included an estimated 4.5 million people with some American Indian or Alaskan native ancestry (2.9 million exclusively of such ancestry) and over 1 million with some native Hawaiian or Pacific island ancestry (0.5 million exclusively).
