Give some stream of consciousness and then the answer. The Iraq War, also known as the Second Gulf War, was a protracted armed conflict that began in 2003 with the invasion of Iraq by a United States-led coalition that overthrew the government of Saddam Hussein. The conflict continued for much of the next decade as an insurgency emerged to oppose the occupying forces and the post-invasion Iraqi government. An estimated 151,000 to 600,000 or more Iraqis were killed in the first 3 -- 4 years of conflict. The U.S. became re-involved in 2014 at the head of a new coalition; the insurgency and many dimensions of the civil armed conflict continue. The invasion occurred under the pretext of a declared war against international terrorism and its sponsors under the administration of US President George W. Bush following the September 11 terror attacks.
