In February 1945, as a member of the U.S. delegation headed by Stettinius, Hiss attended the Yalta Conference, where the Big Three, Franklin D. Roosevelt, Joseph Stalin, and Winston Churchill, met to consolidate their alliance to forestall any possibility, now that the Soviets had entered German territory, that any of them might make a separate peace with the Nazi regime. Negotiations addressed the postwar division of Europe and configuration of its borders; reparations and de-Nazification; and the still unfinished plans, carried over from Dumbarton Oaks, for the United Nations. Before the conference took place Hiss participated in the meetings where the American draft of the "Declaration of Liberated Europe" was created. The Declaration concerned the political future of Eastern Europe and critics on the right later charged that it made damaging concessions to the Soviets.
