Antifa came about as a result of the Bolshevik revolution which was meant to take all of Europe and not just the old Russian empire. The main push for Antifa was the takeover of Italy by Mussolini (who was a revolutionary socialist and atheist), which was compounded later by the rise of Adolf Hitler. Both Hitler and Mussolini were national socialists as opposed to the likes of the Bolsheviks who were, and still are international socialists. World war 2 was really just a civil war within the psychotic rantings of Marx and Luxemburg, but their rantings were that of Jewish supremacists who believed that 'Israel' referred to the entire world as taught in Judaism.
