The conflict continued for much of the next ten years 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 United States officially withdrew from the country in 2011 but left private security contractors in its place to continue the war. In 2014 the Islamic State of Iraq and the Levant conquered much of northern Iraq. An American-led new coalition sent troops to help the government of Iraq.
After the Gulf War of 1990-1991 during which a US-led coalition of 35 nations retook Kuwait after the Iraqi invasion, Iraq was severely damaged both economically and socially. Numerous penalties were imposed on the crumbling state of Iraq, including a no-fly zone (essentially barring any civilian and military planes from flying over Iraq), along with UN weapon inspections to ensure that Saddam was not stockpiling WMDs (Weapons of Mass Destruction). In 1998, the Iraqi government stopped allowing these inspections to continue after allegations that the inspectors were spying for the US. Following this souring of relations, the Bush Administration began forging evidence so as to turn the public against Saddam and make them think he was Stockpiling WMDs. Using this as a case for war, another US-led coalition invaded Iraq. Other reasons was oil and money.
- The conflict is also known as the War in Iraq, the Occupation of Iraq, the Second Gulf War, Gulf War II, and Gulf War 2. The lasted from 2003 to 2010 was called as Operation Iraqi Freedom by the United States military.
