Yalta was the second of three war conferences among the Big Three, preceded by the Tehran Conference in 1943 and followed in July 1945 by the Potsdam Conference, which was attended by Stalin, Churchill (replaced mid-term by the new British Prime Minister Clement Attlee) and Harry S. Truman, Roosevelt`s successor. The Yalta conference was a turning point in the Cold War. Stalin took a hard line on the question of Poland, pointing out that in three decades, Germany had used the nation twice as a corridor to invade Russia. He stated that the Soviet Union would not return the Polish territory annexed in 1939 and would not comply with the requirements of the Polish government in exile, which is headquartered in London. 3. The United States Government should, on behalf of the three powers, consult with the Chinese government and the French provisional government on the decisions taken at this conference on the proposed World Organization. 4. With regard to the determination of the total amount of reparation and its distribution among the countries suffering from German aggression, the Soviet and American delegations agreed that the aim of the conference was to build a post-war peace that constituted not only a collective security order, but a plan for self-determination of the liberated peoples of post-Nazi Europe. The meeting should focus on the restoration of the nations of war-torn Europe. But within a few years, as the Cold War divided the continent, Yalta became the subject of intense controversy.
Roosevelt wanted the USSR to join the Allies in the Pacific War against Japan, which he hoped would end the war sooner and reduce American casualties. “In Poland, the total liberation of the Red Army has created a new situation. This requires the formation of a provisional Polish government, which may be broader than it was before the recent liberation of the western part of Poland. The provisional government, which is currently operating in Poland, should therefore be reorganized on a broader democratic basis, with the participation of Polish democratic leaders themselves and Poland abroad. This new government should then be called Poland`s provisional government of national unity. The Big Three also agreed that democracies should be established, that all European countries and former satellites liberated from the Axis powers should hold free elections and that order be restored.  In this regard, they promised to rebuild countries occupied by processes that would enable them to “create democratic institutions of their choice. It is a principle of the Atlantic Charter, the right of all peoples to choose the form of government under which they will live.  The resulting report stated that the three occupied countries would assist the occupied countries in forming a transitional government to “facilitate the rapid implementation of governments that respond to the will of the people” and “facilitate the holding of such elections” and “facilitate, where appropriate, the organization of such elections.”  4. The text of the invitation to all nations participating in the United Nations Conference should be as follows: 2. The nations to be invited to this conference should be as follows: in order to promote the conditions under which the freed persons can exercise these rights, the three governments will be aimed at the people in any liberated European state or former Axis State in Europe in which the three heads of state and government have attempted to , according to their conditions of judgment, to define an agenda for the leadership of post-war Europe and for peace between post-war countries. On the Eastern Front, the front line remained in the Soviet Union at the end of December 1943, but in August 1944, Soviet troops were in Poland and Romania as part of their journey west.
