Nazism was the first weapon of mass destruction and it was levelled against communism in Germany and Europe. When the nazis were on the brink of power the ruling classes pushed them over the brink with their hatred, fear and derision of working class gains in Germany and Europe at the time. Rebellion to capitalism was spreading and the ruling classes wanted a solution. Nazism is a reactionary derivative of capitalism and nothing else. It only exists in capitalism. Malcolm X always said 'you can't have capitalism without racism'.
