In late 1943, Roosevelt, Churchill, and Stalin agreed to meet to discuss strategy and post-war plans at the Tehran Conference, which marked Roosevelt's first face-to-face meeting with Stalin. At the conference, Britain and the United States committed to opening a second front against Germany in 1944, while Stalin committed to entering the war against Japan at an unspecified date. Roosevelt also privately indicated acceptance of Soviet control of the Baltic states and Soviet plans to shift Poland's borders to the west. Stalin, meanwhile, committed to joining the war against Japan after the defeat of Germany.
