McCain, Churchill and Appeasement
From the Oxford Dictionary of National Biography, entry on appeasement.
Churchill's record as an uncomplicated anti-appeaser cannot go unchallenged. His contemporary criticism of totalitarian regimes other than Hitler's Germany was at best muted, and it was not until May 1938 [Josh: after the Nazi occupation of Austria] that he began consistently to withhold his support from the National Government's conduct of foreign policy in the division lobbies of the House of Commons. Even then, Churchill seems to have been convinced by the Sudeten German leader, Henlein, in the spring of 1938, that a satisfactory settlement could be reached if Britain managed to persuade the Czech government to make concessions to the German minority.
