I'm sure Gen. Colin Powell is a man of conviction and integrity who would not knowingly participate in the deception of the American people. He repeated what he was told by the administration when he stated he had proof of weapons of mass destruction in Iraq.
No proof of these lethal weapons has as yet come to light. He was a pawn, used by the administration to frighten the public into accepting the resulting invasion of Iraq without proof that these weapons existed. This is another example of the way this administration manipulated the facts to come up with a result that was favorable to their ideology, that the end justifies the means.
