UN's demand. Even now, we are prepared to go the extra step to achieve disarmament peacefully." Secretary of State Powell said in his 5 February 2003 presentation to the UN Security Council: On 11 February 2003, FBI Director Robert Mueller testified to Congress that "Iraq has moved to the top of my list. As we previously briefed this Committee, Iraq's weapons of mass destruction program poses a clear threat to our national security, a threat that will certainly increase in the event of future military action against Iraq. Baghdad has the capability and, we presume, the will to use biological, chemical, or radiological weapons against US domestic targets in the event of a US invasion."

After the invasion, despite an exhaustive search led by the Iraq Survey Group involving a more than 1,400 member team, no evidence of Iraqi weapons programs was found. On the contrary, the investigation concluded that Iraq had destroyed all major stockpiles of weapons of mass destruction and ceased production in 1991 when sanctions were imposed. The failure to find evidence of Iraqi weapons programs following the invasion led to considerable controversy in the United States and worldwide, including claims by critics of the war that the Bush and Blair administrations deliberately manipulated and misused intelligence to push for an invasion. UN inspections before the invasion Between 1991 and 1998, the United Nations Security Council tasked the United Nations Special Commission on Disarmament (UNSCOM) with finding and destroying Iraq's weapons of mass destruction. In 1996, UNSCOM discovered evidence of continued biological weapons research and supervised destruction of the Al Hakum biological weapons production siteallegedly converted to a chicken feed plant, but retaining its barbed wire fences and antiaircraft defenses. In 1998, Scott Ritter, leader of a UNSCOM inspection team, found
