 According to French spymaster and writer Henri Rollin, "Hitlerism" was based on "anti-Soviet counter-revolution" promoting the "myth of a mysterious Jewish–Masonic–Bolshevik plot", entailing that the First World War had been instigated by a vast Jewish–Masonic conspiracy to topple the Russian, German, and Austro-Hungarian Empires and implement Bolshevism by fomenting liberal ideas.A major source for propaganda about Jewish Bolshevism in the 1930s and early 1940s was the pro-Nazi and antisemitic international "Welt-Dienst" news agency founded in 1933 by Ulrich Fleischhauer.Within the German Army, a tendency to see Soviet Communism as a Jewish conspiracy had grown since the First World War, something that became officialized under the Nazis.
