On 2 August 1945, the Potsdam Agreement, proclaimed at the end of the Potsdam Conference, agreed, among other things, on the initial conditions under which the World War II Allies were to rule Germany. A temporary German-Polish border, known as the Oder-Neisse line, has in theory attributed most of the German provinces in eastern Germany to Poland and the Soviet Union as part of this „temporary border”. The German population in these areas has been displaced or killed. These agreements were provisional and the agreement provided that the situation would be concluded by „a peace settlement for Germany accepted by the German government if an appropriate government is formed” (Potsdam Agreement 1.3.1). Parts of these agreements mentioned above have been riddled with controversy from several sources, z.B. Churchill`s comment on „the Polish goose too full” (by German countries). The „German question” has become one of the most important and crucial issues of the long-running Cold War, and until the late 1980s there had been little progress in forming a single German government, appropriate to the agreement on a final settlement. This meant that Germany, in some respects (to a large extent, but not only technically), was not taking over full national sovereignty. 42-43 The leaders of the great Allied powers of the Second World War met on 12 February 1945 in Yalta, Crimea, to decide on military plans for the final defeat of Germany.
On February 11, 1945, the Conference announced that this issue had been resolved and called for a United Nations conference to be held on April 25, 1945 in San Francisco „to prepare the charter of such an organization as proposed in the formal discussions of Dumbarton Oaks.” The invitations were sent on 5 March 1945 and the guests were simultaneously informed of the agreement reached in Yalta on the voting procedure in the Security Council. Shortly thereafter, in early April, President Roosevelt died suddenly. President Truman has decided not to postpone the arrangements already made for this important event that took place on the scheduled date. San Francisco Conference (1945) 45 nations, including the four sponsors, were initially invited to the San Francisco conference: nations that had declared war on Germany and Japan and signed the United Nations Declaration. Six other countries were invited: Syria and Lebanon (at the request of France), Argentina, newly liberated Denmark, the Belarusian Socialist Republic and the Soviet Ukrainian Socialist Republic. Delegates from 50 nations gathered in San Francisco. In a speech to Congress in January 1918, Wilson outlined his idealistic vision of the post-war world. In addition to the specific territorial settlements, which are based on a victory of the Agreement, Wilsons stressed the need for national self-determination for the different ethnic groups in Europe. Wilson also proposed the creation of a „general association of nations” that would transmit international disputes and promote cooperation between nations, with the hope of avoiding war on such a scale in the future. This organization was eventually known as the League of Nations. Representatives of the Soviet Union, the United Kingdom and the United States meet at the opening of the conference on the organization of security for post-war world peace.
