In a 2006 interview Wilkerson said that the speech Powell made before the United Nations on February 5, 2003—which laid out a case for war with Iraq—included falsehoods of which Powell had never been made aware. He said, "My participation in that presentation at the UN constitutes the lowest point in my professional life. I participated in a hoax on the American people, the international community and the United Nations Security Council." Wilkerson said in 2011 that his preparing of the presentation was "probably the biggest mistake of my life", he regrets it, and that he regrets not resigning over it.
