Have you bothered reading the text of David Kay's statement to Congress? If you have, then you know that he whole-heartedly agrees with President Bush's decision to go to war based on the evidence that was known before the war and what has been learned after. He even went so far as to say that Iraq may have been more dangerous than previously believed based on what has been learned since the end of the war.
