More than 20 nations (most notably the United Kingdom), designated the "coalition of the willing" joined the United States in invading Iraq. They launched the invasion on March 20, 2003. The Iraqi military was quickly defeated. The capital, Baghdad, fell on April 9, 2003, which resulted in the overthrow of Saddam Hussein's Ba'athist regime 24 year rule. On May 1, Bush declared the end of major combat operations in Iraq. The initial success of U.S. operations increased his popularity, but the U.S. and allied forces faced a growing insurgency led by sectarian groups; Bush's "Mission Accomplished" speech was later criticized as premature. President Bush then appointed Paul Bremer Presidential Envoy to Iraq on May 9, 2003 and administrator of the Coalition Provisional Authority, his appointment declared him subject to the "authority, direction and control" of Secretary of Defense Donald Rumsfeld. On December 14, 2003, President Bush announced the capture of Saddam Hussein, after U.S. forces captured him in Operation Red Dawn and said that Saddam would "face the justice he denied to millions. For the Ba'athist holdouts responsible for the violence, there will be no return to the corrupt power and privilege they once held". From 2004 until 2007, the situation in Iraq deteriorated further, with some observers arguing that there was a full-scale civil war in Iraq. Bush's policies met with criticism, including demands domestically to set a timetable to withdraw troops from Iraq. The 2006 report of the bipartisan Iraq Study Group, led by James Baker, concluded that the situation in Iraq was "grave and deteriorating". While Bush admitted there were strategic mistakes made in regards to the stability of Iraq, he maintained he would not change the overall Iraq strategy. According to Iraq Body Count, some 251,000 Iraqis have been killed in the civil war following the U.S.-led invasion, including at least 163,841 civilians.
