Truman was much more suspicious of the Soviets than Roosevelt and increasingly suspicious of Stalin`s intentions.  Truman and his advisers regarded Soviet action in Eastern Europe as aggressive expansionism, incompatible with the agreements Stalin had been obliged to in Yalta in February. In addition, Truman discovered possible complications elsewhere when Stalin rejected Stalin Churchill`s proposal to withdraw the Allies from Iran before the timetable agreed at the Tehran conference. The Potsdam conference was the only time Truman met Stalin himself.   The agreement was presented as a communiqué and was not a peace treaty between the peoples, although it established the fait accompli. It was replaced by the Treaty on the Definitive Regime, signed on 12 September 1990, in accordance with Germany. The three governments took note of discussions in recent weeks in London between representatives of the United Kingdom, the United States, the Soviet Union and France to reach agreement on the methods of trial of major war criminals whose crimes do not present a particular geographical location after the Moscow Declaration of October 1943. The three governments reaffirm their intention to bring justice quickly and safely to these criminals. They hope that the London negotiations will lead to a quick agreement to that end, and they believe it is very important that the trial of these great criminals begins as soon as possible.
The first list of accused will be published before September 1. The problem of war reparation proved to be one of the most difficult to deal with in post-war conditions. The Soviet Union, the country most devastated by the war, felt eligible for the largest possible amounts, with the exception of Bulgaria, considered the friendliest of the former enemy states. (Bulgaria was part of the axis, but did not declared war on the Soviet Union). In Romania and Hungary, the reparation conditions set out in their weapons were relatively high and were not revised. The foreign ministers of the three governments – James F. Byrnes, V.M Molotov and Anthony Eden and Ernest Bevin – and other advisers also attended the conference. Nine meetings were held from July 17 to 25. Subsequently, the conference was suspended for two days, with the results of the British general election announced.
