At that time, the Soviet army occupied Poland entirely and held much of Eastern Europe with a military power three times greater than the Allied forces of the West.

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.  After Yalta in the USSR, when Soviet Foreign Minister Vyacheslav Molotov worried that the wording of the Yalta agreement might hinder Stalin`s plans, Stalin replied: “Don`t worry. 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.  The Yalta Conference took place from 4 to 11 February 1945, during the Second World War, at a Russian resort in Crimea.
In Yalta, U.S. President Franklin D. Roosevelt, British Prime Minister Winston Churchill and Soviet Prime Minister Joseph Stalin made important decisions on the future progress of the war and the post-war world.
