Iraq War

 or Second Persian Gulf War

Brief conflict in 2003 between Iraq and a combined force of troops largely from the U.S. and Great Britain; and a subsequent U.S.-led occupation of Iraq and protracted Iraqi armed insurgency against it. The trade embargo and weapons-inspection process that the UN imposed on Iraq following the Persian Gulf War (1990–91) had partly fallen into abeyance by 2001. U.S. Pres. George W. Bush argued that the September 11 attacks on the U.S. in that same year highlighted the threat to U.S. security posed by hostile countries such as Iraq. In November 2002 the UN issued Security Council Resolution 1441 demanding that Iraq readmit weapons inspectors and comply with all previous resolutions. Although inspectors did return to Iraq, Bush and Blair declared in early 2003 (despite objections by many world leaders) that Iraq was continuing to hinder UN inspections and that it still retained proscribed weapons. On March 20 the U.S. and Britain (with smaller troop contingents from other countries) launched a series of air attacks on Iraq, and a ground invasion followed. Iraqi forces were rapidly defeated, and on April 9 U.S. forces took control of the capital, Baghdad. British forces completed their occupation of the southern city of Al-Basrah the same day, and by May 1 the major combat operations of the invasion had been completed. However, the U.S. and other occupying forces were soon embroiled in escalating guerrilla warfare in Iraq that hindered Iraq's recovery and killed thousands of soldiers and tens of thousands of civilians. The war, long opposed by many throughout the world, also became increasingly unpopular in the U.S.
