I have respect for much that GWB has said and done but, in the words of John McEnroe, he cannot be serious in comparing Blair to Churchill. http://www.sky.com/skynews/article/0,,30100-12985691,00.html
Not any worse than comparing his Iraqi Inquiry commission to the Warren commision who investigated JFK's assassination.
But then if the conspiracy theorists are correct, the Warren Commission didn't do a very good job; the whole inquiry resulted in a cover-up.
