"From late November 2002 to March 2003, U.N. inspectors combed Iraq looking for weapons of mass destruction (WMD). Under the threat of war from the United States and a unanimous Security Council resolution (1441), Iraq was granted a final opportunity to disarm. Many had low expectations for successful inspections. After 16 weeks, inspectors turned up some evidence of undeclared activities, but not enough to convince a majority of the Security Council members that military force was necessary. Nonetheless, on March 19, 2003, U.S. and British forces attacked Iraq to forcibly eliminate its WMD. This report, which will be updated as events warrant, analyzes the inspections, their outcome, and possible future tasks."
