It has always been a Great Truth that the Nazis had far more in common with the political left than the political right.
The NAZIs were just another flavor of the political Left.
Stalin and Hitler were simpatico until Hitler got greedy.
Mussolini was a former de facto communist.
Hitler & NAZIism were not really racist; the Jews were the scapegoats.
Hitler had no problem allying with the non-Aryan Turkish Muslims. He had no problem allying with the very non-Aryan Imperialist Japanese.
The common denominator was always Totalitarianism - with a capital T, and that stood for Trouble.
Hitler despised Christianity (though he temporarily and only publicly gave it lip service to dupe the German masses) and admired Mohammedanism because he hated liberty and loved tyranny.
The Left always lies about their own being what they truly are.
