and preventive measure" on the part of the Germans for the "class genocide" of the Bolsheviks. American historian Peter Baldwin noted parallels between Nolte's views and those of American Marxist historian Arno J. Mayer:. Both Nolte and Mayer perceive the interwar period as one of intense ideological conflict between the forces of the Right and Left, positing World War II as the culmination of this conflict, with the Holocaust a byproduct of the German-Soviet war. Baldwin distinguished Nolte from Mayer in that Nolte considered the Soviets aggressors who essentially got what they deserved in the form of Operation Barbarossa, whereas Mayer considered the Soviets to be victims of German aggression. Operation Barbarossa, in Nolte's thinking, was a "preventive war" forced on Hitler by an alleged impending Soviet attack. Nolte wrote that Hitler's view of the Russian people as barbarians was an "exaggeration of an insight which was basically right in its essence" and that Hitler "understood the invasion of the Soviet Union as a preventive war" as the Soviet desire to bring Communism to the entire world "must be seen as mental acts of war, and one may even ask whether a completely isolated and heavily armed country did not constitute a dangerous threat to its neighbors on these grounds alone". The crux of Nolte's thesis was presented when he wrote: "It is a notable shortcoming of the literature about National Socialism that it does not know or does not want to admit to what degree all the deeds—with the sole exception of the technical process of gassing—that the National Socialists later committed had already been described in a voluminous literature of the early 1920s: mass deportations and shootings, torture, death camps, extermination of entire groups using strictly objective selection criteria, and public demands for the annihilation of millions of guiltless people who were thought to be "enemies". It is probable that many of these reports were exaggerated. It is certain that the “White Terror” also committed terrible deeds, even though its program contained no analogy to the “extermination of the bourgeoisie”. Nonetheless, the following question must seem permissible, even unavoidable: Did the National Socialists or Hitler perhaps commit an “Asiatic” deed merely because they and their ilk considered themselves to be the potential victims of an “Asiatic” deed? Wasn't the 'Gulag Archipelago' more original than Auschwitz? Was the Bolshevik murder of an entire class not the logical and factual
