See-Dubya, who is subbing in for Michele Malkin on her blog while she hunts down Jamil Hussein who might, or might not exist, writes about the Times of London which is suggesting the theory was that since Hitler's crazy-evil leadership was hampering the German war effort, it was in the Allies' interest to keep him alive and not let someone more competent take over. This may be the reasoning behind a real-life decision by the Brits not to promote a suicide mission to kill Hitler by a safecracker and explosives expert named Eddie Chapman. Chapman had been sprung from prison in the Jersey Islands by the Germans, who recruited him as a spy. Chapman promptly defected to MI5 and volunteered to use the trust of his German spymasters to get close to Hitler and blow him up. Instead, he went back and served out the war as a double agent working for England, but so convincing that the Germans gave him an Iron Cross. Read about it here.
