I would agree with Pete. I think that Germany in WW2 was paranoid as well as racist. The Nazis were willing to kill everyone and anyone. They would kill their own citizens, who made any resistance, they killed the sick and the disabled, and they killed people from other nations to make space for "liebesraum". In some ways they were not totally racist. They didn't like Jews but they did like Muslims, because Muslims were happy to fight and kill without regard for their own lives. There were many Muslim Wehrmacht and SS military units..
