In this atmosphere of growing conflict, Mussolini persuaded Hitler to put the dispute to a four-power conference and on 29 September 1938, Hitler, Chamberlain, Édouard Daladier (the French Prime Minister) and Mussolini met in Munich. Czechoslovakia was not to be a party to these talks, nor was the Soviet Union. The four powers agreed that Germany would complete its occupation of the Sudetenland but that an international commission would consider other disputed areas. Czechoslovakia was told that if it did not submit, it would stand alone. At Chamberlain's request, Hitler readily signed a peace treaty between the United Kingdom and Germany. Chamberlain returned to Britain promising "peace for our time". Before Munich, President Franklin D. Roosevelt sent a telegram to Chamberlain saying "Goodman", and afterward told the American ambassador in Rome, "I am not a bit upset over the final result."
