At the conference, Allied leaders reaffirmed their previous commitment to the expulsion of the German population from Poland, Czechoslovakia and Hungary; governments in these countries had already implemented. Potsdam`s three allies were convinced that the transfer of this German population should be completed as soon as possible. They stressed that transfers should be carried out in an orderly and humane manner. In the long run up to two million German civilians were killed in forced displacement.

After the war, “Germany as a whole” would consist exclusively of aggregate zones of the affected areas of occupation. All the former German territories east of the Oder-Neisse line were excluded from the Soviet zone of occupation, so they were excluded from “Germany as a whole”. 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. The Yalta conference granted France an area of occupation within Germany.
France participated in the Berlin Declaration and is expected to be a member of the Allied Control Council on an equal footing. However, at the request of the Americans, Charles de Gaulle was not invited to Potsdam, as he had been denied representation in Yalta. The little diplomatic thing was for him a cause of deep and persistent resentment.  The reasons for this omission were the long-standing personal antagonism between Roosevelt and de Gaulle, the continuing quarrels over the French and American zones of occupation, and the expected conflicts of interest over French Indochina.  It also reflected the British and American judgment that the French objectives on many of the conference agenda were probably at odds with the agreed Anglo-American objectives.  The protocols of the Potsdam Conference suggested continued harmony between the Allies, but the deeply contradictory objectives of Western democracies on the one hand and the Soviet Union on the other, meant that Potsdam became the last Allied conference.
