I believe this is Neville Chamberlain, the Great Appeaser of Hitler.

That's right! The current PM of Great Britain. Last year he signed the Munich Agreement, allowing Hitler to take the Sudetenland from the Czechs. Now Prague is overrun with Nazis, and history will never forgive or forget Chamberlain's decision. Years from now Churchill will admit British liability for this lapse in judgment but also blame the French:

"For the French Government to leave her faithful ally Czechoslovakia to her fate was a melancholy lapse from which flowed terrible consequences. Not only wise and fair policy, but chivalry, honour, and sympathy for a small threatened people made an overwhelming concentration. Great Britain, who would certainly have fought if bound by treaty obligations, was nevertheless now deeply involved, and it must be recorded with regret that the British Government not only acquiesced but encouraged the French Government in a fatal course."

We still don't have "peace in our time."
