Neville Chamberlain had taken far too long, some said, to admit failure. So they gave him a hard push. Britain's prime minister imagined that he had appeased Hitler. He may have deterred him, but only for a brief time. He did not dissuade, disarm, or destroy him. Hitler took the Sudetenland and dismembered Czechoslovakia; he had conquered his piece of Poland and allowed Stalin to grab the rest; he had invaded Denmark and Norway, "fascinated, browbeaten, cajoled and then garotted." The way was open to France, and everyone, or nearly everyone, knew it. In May 1940, Europe was again at war. And in Britain, Chamberlain got the blame.
