Before the Fall of France in 1940, how much hope did Britain and France have in the success of an internal coup against the Nazis? Specifically, were Britain and France banking on the possibility that, in the event that a Nazi invasion of France fails, anti-Nazis within the German military would successfully overthrow Hitler and the Nazis and quickly negotiate a compromise peace with Britain and France on Anglo-French terms?

Or were Britain and France expecting a long war even before the Fall of France--with them not being confident in the ability of anti-Nazi Germans to successfully overthrow Hitler and the Nazis?
