Victor Davis Hanson and Christopher Hitchens take on the WWII revisionists, centering on Patrick J. Buchanan, the author, most recently, of Churchill, Hitler, and the Unnecessary War. In terms of the origins of the conflict, Buchanan says essentially that Britain’s guarantee to protect Poland in the event of a German invasion made the war inevitable. Hanson counters that Germany’s invasion of Poland was not an isolated act. Hitchens says Buchanan is “consciously trying to deceive us.”
