On March 20, 2003 (February 18, 2003 in the lunar calendar), the Iraq War broke out. On March 20, 2003, the US-British coalition forces launched military operations against Iraq without authorization from the United Nations Security Council. On April 9, U.S. troops invaded Baghdad. On May 1, U.S. President Bush announced the end of the main war in Iraq. On July 13, the Iraq Interim Governing Council was established. On December 13, Saddam Hussein was captured by the US military near his hometown of Tikrit. The United States '"pre-emptive" strategy and unilateralism tendency have caused internal divisions in the Atlantic Alliance, and conflicts between the United States, Europe and Russia have become prominent. However, under the dual pressure of post-war reconstruction and guerrilla warfare in Iraq, the United States and Britain had to resort to the United Nations multilateral framework and propose a timetable for the early transfer of power to Iraq. The little girl who fled Basra during the war lost more than 400 U.S. military boots from her owner. On March 20, 2003, the U.S. military led the Iraq War. Although it successfully overthrew Saddam Hussein's regime, it opened the "Pandora's Box" in the Middle East, breaking the region's original balance of power, and causing continued turmoil in the Middle East. In the United States, it is even difficult to estimate the cost of this "burning money" battle. Compared with the direct costs of military spending, the indirect costs are an "bitter fruit" for the Obama administration, which is "fighting" with the deficit. The latest poll results released by polling agency Gallup on March 18, 2013 showed that 53% of Americans believe that the Iraq War was a mistake. Gallup believes that the United States 'overseas military operations in recent decades have caused major divisions among the public, and Americans will become more cautious when supporting similar operations in the future.
