He had often fought with the hawks in the administration, who were allegedly planning an Iraq invasion even before the September 11 attacks-an insight supported by evidence by former terrorism czar Richard Clarke in front of the 9/11 Commission.
The main concession Powell wanted before he would offer his full support for the Iraq War was the participation of the international community in the attack, unlike the one-sided approach some of the hawks were championing. He was also thriving in convincing Bush to take the case of Iraq to the United Nations, and in moderating other initiatives. Powell was placed at the vanguard of this diplomatic campaign. Powell's main role was to gather international support for a multi-national alliance to increase the invasion. To this end, Powell addressed a plenary session of the United Nations Security Council on February 5, 2003 to bicker in favor of military action. Quoting "numerous" nameless Iraqi defectors, Powell declared that "We know that Saddam Hussein is determined to keep his weapons of mass destruction, is determined to make more." (Cockburn, online) Powell also remarked that there was "no doubt in my mind" that Saddam was working to acquire key components to produce nuclear weapons.
There was a general rejection of the proof Powell offered that the regime of Saddam Hussein had weapons of mass destruction.
