Well, his better speeches were done by an actor, he was one of the main people responsible for Gallipoli, and his stint as Chancellor of the Exchequer was a disaster. As for his support of war and criticisms of appeasement prior to the war, I really don't see how England, at the time, had any choice but to appease Germany. If they had pushed for war too early, they would have been crushed by the Germans as quickily as the rest of Europe and what good would that have done. In any case, his disdain of appeasement derived mostly from his romantic, nationalist view of England as the strong, imperialist nation of Victorian times, which had very little to do with actual fact.
Oh yeah, and he was a big fan of Mussolini.
