Ludwig Von Mises said this quote
“ All Nazi champions insist again and again that Marxism and Bolshevism are the quintessence of the Jewish mind, and that it is the great historic mission of Nazism to root out this pest. It is true that this attitude did not prevent the German nationalists either from coöperating with the German communists in undermining the Weimar Republic, or from training their black guards in Russian artillery and aviation camps in the years 1923–1933, or— in the period from August, 1939, until June, 1941—from entering into a close political and military complicity with Soviet Russia. Nevertheless, public opinion supports the view that Nazism and Bolshevism are philosophies—Weltanschauungen—implacably opposed to each other. ”
