Weren't all major WWII militaries mainly made up of conscripts, that is people who were fighting involuntarily?
The only difference there was how harshly disobedience was punished. US Army never shot deserters or people who refused to fight out of hand, but then, it was never engaged in a life and death struggle against the Wehrmacht for three years.

You are so wrong it's not funny. Nazism doesn't spread well, because it is a racist ideology with limited appeal for non-Aryans. Communism, or it's milder forms, on the other hand, is to be found almost everywhere..
