One of the key points of the Yalta agreement was the approval of the unconditional surrender of Nazi Germany. After the war, Germany and Berlin were divided into four occupied areas. Stalin agreed that France would have a fourth zone of occupation in Germany, but it should be formed from the American and British zones. After Yalta in the USSR, when Soviet Foreign Minister Vyacheslav Molotov worried that the formulation of the Yalta agreement could hinder Stalin`s plans, Stalin replied: “Never anything. We will do it later in our own way.  While the Soviet Union had already annexed several occupied countries such as (or in Soviet republics), , other countries it occupies in Central and Eastern Europe have been transformed into Soviet satellite states, such as the People`s Republic of Poland, the People`s Republic of Hungary the Czechoslovakian Socialist Republic the People`s Republic of Romania, the People`s Republic of Bulgaria , the People`s Republic of Bulgaria, the People`s Republic of Albania, and later East Germany of the Soviet zone of occupation. Finally, the United States and the United Kingdom made concessions on the recognition of the then Communist-dominated regions and sacrificed the substance of the Yalta Declaration while remaining in form.  On March 1, Roosevelt assured Congress: “I come from Crimea with the firm conviction that we have begun on the road to a world of peace.”  However, the Western powers soon realized that Stalin would not keep his promise of free elections for Poland. After receiving considerable criticism in London after Yalta of the atrocities committed by Soviet troops in Poland, Churchill wrote a desperate letter to Roosevelt in which he referred to the large-scale deportations and liquidations of opposition Poles by the Soviets.  On March 11, Roosevelt replied to Churchill and wrote, “I am sure we must stand firm on a correct interpretation of Crimea`s decision. They rightly believe that neither the government nor the people of this country will support participation in fraud or mere deception by the Lublin government, and the solution must be as we imagined it in Yalta.  In return, Stalin promised that three months after Germany`s defeat, the Soviet Union would enter the Pacific War.
Later, in Potsdam, Stalin promised President Truman to respect the national unity of Korea, which would be partially occupied by Soviet troops. The Declaration of Liberated Europe was launched by Winston Churchill, Franklin D. Roosevelt and Joseph Stalin at the Yalta Conference. It is a promise that will enable European citizens to “create the democratic institutions of their choice.” The declaration says: “The fastest possible implementation by free elections” that respond to the will of the people. This is similar to the statements of the Atlantic Charter, in which it says “the right of all men to choose the form of government under which they will live.”  Each of the three leaders had their own agenda for post-war Germany and liberated Europe. Roosevelt wanted Soviet support in the American Pacific War against Japan, particularly for the planned invasion of Japan (Operation August Storm) and Soviet participation in the United Nations; Churchill insisted on free elections and democratic governments in Central and Eastern Europe (particularly Poland); Stalin called for a Soviet sphere of political influence in Central and Eastern Europe as an essential aspect of the USSR`s national security strategy.
