The main objective of the Potsdam conference was to put an end to the post-war period and to put into practice all that had been agreed in Yalta. While the Yalta meeting was rather friendly, the Potsdam conference was marked by differences of opinion that were the result of some important changes since the Yalta conference. Despite many disagreements, Allied leaders managed to reach some agreements in Potsdam. Negotiators thus confirmed the status of Germany demilitarized and disarmed among the four zones of the Allied occupation. According to the protocol of the conference, there should be “complete disarmament and demilitarization of Germany”; all aspects of German industry that could be used for military purposes should be removed; all German military and paramilitary forces should be eliminated; and the manufacture of all military equipment in Germany was prohibited. In addition, German society should be redeveloped by the repeal of all discriminatory laws of the Nazi era and by the arrest and trial of Germans considered “war criminals” on the democratic model. The German education and judicial system should be purged of all authoritarian influence and democratic political parties would be encouraged to participate in the management of Germany at the local and national levels. However, the re-establishment of a German national government was postponed indefinitely and the Allied Control Commission (composed of four occupying powers, the United States, Great Britain, France and the Soviet Union) would rule the country during the interregnum. Britain and the United States were still at war with Japan, but the absence of a common enemy in Europe created immense difficulties in Potsdam to reach consensus on the political reconstruction of Europe after the war.
Potsdam was also lacking the optimism and kindness and kindness, but sometimes forced, as well as the “atmosphere of compromise” of Tehran and Yalta. But the biggest stumbling blocks in Potsdam were the fate of post-war Poland, the revision of its borders and borders in Germany, and the expulsion of millions of ethnic Germans from Eastern Europe. The issue of Poland had been raised at the Tehran and Yalta conferences.
