FILE- In this March 24, 1938, file photo, German troops reach Vienna, Austria shortly after the annexation of Austria into Nazi Germany. In 1938, a year before the outbreak of the Second World War, Nazi Germany annexed large swaths of territory in central Europe with Western acquiescence, the now widely derided policy of appeasement. The Nazis annexed Austria in what was known as the Anschluss, or joining, and held a referendum that passed with 100% approval. They then annexed the Sudetenland from Czechoslovakia in the now-infamous Munich agreement negotiated with British Prime Minister Neville Chamberlain. (AP Photo, File)
