Several examples demonstrate that some Abwehr members were opposed to the Nazi regime. In January 1944 for example, American statesman John Foster Dulles revealed his knowledge of a coalescing resistance against the Nazis, an assemblage of intellectuals from military and government circles; his main contact was Abwehr officer Hans Bernd Gisevius, who was stationed in Zurich as the German Vice Consul.[77] Dulles communicated with the Abwehr concerning their intrigue against Hitler and even attempted discussions about a separate peace, but President Franklin D. Roosevelt would have none of it, preferring instead a policy of unconditional surrender for the Nazi government.[77] Machinations against the National Socialists by the Abwehr were considerable in terms of the chain of command.
