Some mainstream Holocaust historians have labeled Mayer a denier. The Israeli historian Yehuda Bauer wrote that Mayer "popularizes the nonsense that the Nazis saw in Marxism and Bolshevism their main enemy, and the Jews unfortunately got caught up in this; when he links the destruction of the Jews to the ups and downs of German warfare in the Soviet Union, in a book that is so cocksure of itself that it does not need a proper scientific apparatus, he is really engaging in a much more subtle form of Holocaust denial".
