Did Neville Chamberlain get a bum rap? What if he HAD to buy time to prepare for the inevitable war against Germany?
You say you don't understand the question? Maybe Chamberlain knew Hitler would renege on the agreement and invade all of Czechoslovakia, Chamberlain himself would be branded as a fool, and war would later unfold -- but at least Britain would have had time to prepare.
Maybe that's what happened?
