The End of Isolation. In 1938 in Munich theBritish Prime Minister Neville Chamberlain made a deal with AdolphHitler allowing Nazi Germany to annex Czechoslovakias Sudetenland.Hailed as a hero for his diplomacy at the time Chamberlain is nowwidely reviled for his policy of appeasement to Nazi aggression.Yet one year later Chamberlain would lead Britain into war againstGermany in defense of Poland once it became clear that appeasementhad failed. By contrast the US did little to halt Hitlers initialexpansion and entered into the war only gradually attemptinguntil attacked directly to sway the outcome without going to waritself. Never again would the US remain so aloof for so long fromsuch a momentous international affair. As such the Second WorldWar represents a turning point in American foreign affairs and itis perhaps hard for us to understand why the US took so long totake effective action against the Axis Powers.
