WW2 wasn't fought because people saw evil in Hitler. I have heard that is what is taught in British schools, but that is not true. WW2 was a fight for survival and nothing else.
Survival of what? Individuals were not threatened; governments were. The argument that government propaganda stirred the population into wanting to fight goes right back to the original argument: people fought because they saw evil (as presented by the propaganda).
Dude, when a country attacks your country, you defend. That is not called 'fighting evil'. That is called survival. Fighting evil means attacking Germany because you got to know how evil Hitler is.
