President Roosevelt, who envisions  the United Nations as his greatest post war legacy, gets commitments from the USSR’s  Josef Stalin to allow free elections in Europe, to meet in San Francisco to draw up a charter for the UN, and to declare war on Japan as soon as Germany capitulates. To allay any Soviet concerns about an accommodation with fascism, FDR and British Prime Minister Winston Churchill agree that any government which has not joined the war against the Axis powers by March 1, 1945 will not be invited to the San Francisco conference. Stalin, for his part, speaks of continuing good relations but warns, prophetically, that after the war will come a difficult time when they will be divided by "diverse interests."
