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.  At the conference, Truman called Stalin a „powerful new weapon” unspecified. Towards the end of the conference, on 26 July, potsdam`s declaration issued an ultimatum to Japan to surrender unconditionally or to face the „rapid and total destruction” that the new bomb did not mention, but promised that „it was not the intention to enslave Japan.” The Soviet Union did not participate in this declaration, as it was still neutral in the war against Japan. Japanese Prime Minister Kantaré Suzuki did not respond, which was seen as a sign that the Japanese Empire had ignored the ultimatum.
 Subsequently, the United States dropped atomic bombs on Hiroshima on August 6, 1945 and nagasaki on August 9, 1945. The justifications cited were that both cities were legitimate military targets and that it was necessary to quickly end the war and preserve American life. After the end of the Second World War in Europe (1939-1945) and the decisions of previous conferences in Tehran, Casablanca and Yalta, the Allies had taken the highest authority over Germany by the Berlin Declaration of 5 June 1945. At the conference of the three powers in Berlin (formal title of the Potsdam Conference) from 17 July to 2 August 1945, they approved and adopted the amstbiss of 1 August 1945. The signatories were Secretary General Joseph Stalin, President Harry S. Truman and Prime Minister Clement Attlee, who had replaced Winston Churchill as the United Kingdom`s representative following the 1945 British general election.
