"Himmler, too, was developing the idea of the Jew as an enemy of the state, less in a legal sense than in a combative sense. Early in 1937, in a lecture to the Wehrmacht on the nature and purpose of the SS, he spelled out the idea that "the enemy in a war is an enemy not only in the military sense, but also an ideological enemy."... Thus, at a time when talk of war was becoming the everyday rhetoric of National Socialist Germany, the SS, too, despite the careful paperwork of the SD, began increasingly to talk of war against an ideological enemy."
