The Allies met on 17 July of the same year for the Potsdam Conference. The summit, which continued until 2 August, brought together leaders from the Soviet Union, the United States and the United Kingdom. By that time Roosevelt had died and Churchill had lost the 1945 election, so there were open disagreements over the conduct of the conference. The aim of the meeting was to discuss the best way to punish Nazi Germany and to build on the thought-provoking decisions taken at the Yalta conference. 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. In Potsdam, little has been agreed. The three heads of state and government at the time had many differences of opinion: give the reasons why the Yalta agreements dissolved in potsdam`s disagreements. 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. Potsdam – July 1945: Germany is defeated, Roosevelt died and Churchill had lost the 1945 elections – so there were open disagreements. Truman came furious at the height of the reparations and the fact that a communist government was created in Poland. Truman did not tell Stalin that he had the atomic bomb. One of the many agreements of the Potsdam conference was that Germans living in Poland, Hungary and Czechoslovakia at the end of World War II should be repatriated to Germany. The Yalta conference in February 1945 was rather successful. Churchill, Roosevelt and Stalin agreed on a number of things: since the 1960s, it has been generally accepted that Truman`s attitude towards communism was partly responsible for the end of the Cold War at the end of 1945. These views have since been questioned, but Truman certainly found it very difficult to arrive with Stalin as Roosevelt had. One of the most controversial topics of the Potsdam conference was the revision of the German-Soviet-Polish borders and the expulsion of millions of Germans from the disputed territories. In exchange for the territory it lost after the rebalancing of the Soviet-Polish border to the Soviet Union, Poland received much of German territory and began deporting German residents from the territories concerned, as well as other nations that held large German minorities.
The Negotiators in Potsdam were well aware of the situation and, although the British and Americans feared that a mass exodus of Germans to Western areas of occupation would destabilize them, they merely stated that “all transfers that take place should be done in an orderly and humane manner” and asked the Poles, Czechs and Hungary to temporarily suspend the additional deportations.
