Some people seem to have an unerring instinct for the wrong side of history. You can rely on them, at critical moments, to abandon friends and accommodate evil, in the name of good. Neville Chamberlain famously chose to talk with Adolph Hitler, and believed him when he agreed to peace in 1938. But Chamberlain was big enough a man to admit he was wrong in 1939, and to throw his support behind the winner when war broke out and he was politically beaten.
