Back to Iran. Talk of a unified Qaeda/Iran/Hezbollah/Syria menace is nonsense as a casual scan of actual Sunni jihadist views will make clear. As Fred Kaplan notes, if Churchill and FDR had operated with the Bush mentality, "they might not have formed an alliance with the Soviet Union (out of a refusal to negotiate with evil Communists), and they might have therefore lost the war."

It's worse than that, though -- they might have proposed attacking the Soviet Union in the middle of the war because Bolshevism and Nazism were both species of Eurofascism.
