The American historian William L. Shirer estimated in his “Rise and Fall of the Third Reich” (1960) that Czechoslovakia, although Hitler was not bluffing about its intention to invade, could have resisted considerably. Shirer believed that Britain and France had sufficient air defence to avoid severe bombing of London and Paris, and could have waged a swift and fruitful war against Germany.  He quotes Churchill as saying that the agreement means that “Britain and France are in a much worse position than Hitler`s Germany.”  After personally inspecting the Czech fortifications, Hitler privately told Joseph Goebbels that “we shed a lot of blood” and that it was fortunate that there had been no fighting.  Czechoslovakia was informed by Great Britain and France that it could either oppose Nazi Germany alone or submit to the prescribed annexations. The Czechoslovakian government single-purposely acknowledged the desperation of the fight against the Nazis, reluctantly capitulated (30 September) and agreed to abide by the agreement. The colony gave Germany, from 10 October, the Sudetenland and de facto control of the rest of Czechoslovakia as long as Hitler promised not to go any further. On 30 September, after some time off, Chamberlain went to Hitler`s house and asked him to sign a peace treaty between the United Kingdom and Germany. After Hitler`s interpreter translated it for him, he was glad to have accepted it.
… The solution to the Czechoslovakian problem that has just been found is, in my opinion, only the prelude to a larger colony in which all Europe can find peace. This morning I had another meeting with the German Chancellor, Mr. Hitler, and this is the document that bears his name, as well as mine. Some of you may have already heard what it contains, but I`d just like to read it to you: ` … We consider the agreement signed last night and the Anglo-German naval agreement as a symbol of the desire of our two peoples never to go to war again.  Later in the meeting, a pre-arranged deception was made to influence and pressure Chamberlain: one of Hitler`s accomplices entered the room to inform Hitler of other Germans killed in Czechoslovakia, and Hitler then shouted: “I will avenge each of them.”
