I was rewriting history, while walking along some cold lakeshore the other day. My thought was: if Churchill had only come to power in 1937, Chamberlain would have been installed to replace him in 1940.
Had Churchill been in power, and refused to sign Munich, he would have been blamed for the outbreak of war.
I can just hear the prattle in an English pub, circa 1950. "He pushed Hitler to it! Had it not been for Churchill, Hitler would have been satisfied with the Sudetenland, and England would never have had to surrender. Everything was Churchill's fault!"
. . . followed by the parallels to today's situation.
