The rationale for the Iraq War, both the 2003 invasion of Iraq and the subsequent hostilities, was controversial. The George W. Bush administration began actively pressing for military intervention in Iraq in late 2001. The primary rationalization for the Iraq War was articulated by a joint resolution of the United States Congress known as the Iraq Resolution. The US claimed the intent was to "disarm Iraq of weapons of mass destruction, to end Saddam Hussein's support for terrorism, and to free the Iraqi people".
