The United States will withdraw all combat troops in Iraq, after 7 years and 5 months from 20 March, from 2003 invasion of Iraq in August 2010. the withdrawl shows that U.S. troops lost the war with dignity. Americans pay a terrible price in this battle and failed to achieve their political goals and economic goals. On March 20, 2003, the United States persisted that Iraq possessed weapons of massive destruction as an excuse and openly launched military operations in Iraq bypass the UN Security Council. However, it failed to find weapons of massive destruction and did not let the Bush administration feel ashamed, because at that time, Americans found a second disguise --- building Iraq into a model of democracy. Bush promised to give post-Saddam Iraq to bring freedom and security. However, after the fall of Saddam Hussein, there are still continuing anti-US armed attacks, sectarian violence, so that the political situation in Iraq is extremely volatile, "security" has become a luxury, continuous exposure of prisoner abuse scandal also allow the "freedom" as a lie.
