Five long months later, on 28 June – exactly five years after the assassination of Archduke François-Ferdinand and his wife in Sarajevo – the leaders of the Allies and the powers associated with it, as well as representatives of Germany, met in the mirror room of the Palace of Versailles to sign the final treaty. By fully passing on the burden of war debt on Germany, imposing severe reparations and creating an increasingly unstable collection of small nations in Europe, the treaty would not ultimately solve the underlying problems that led to the outbreak of war in 1914 and would help pave the way for a massive new global conflict 20 years later. After World War II, communist influence in Southeast Asia also increased, along with the People`s Republic of China, when the Chinese Communist Party emerged victorious in the Chinese Civil War in 1949. The Convention for the Prevention and Punishment of the Crime of Genocide (Convention on Genocide) is an instrument of international law that, for the first time, codified the crime of genocide. The Genocide Convention was the first human rights treaty adopted by the UN General Assembly on 9 December 1948 and meant the commitment of the international community to “never work again” after the atrocities of the Second World War. Its adoption was a decisive step on the road to the development of international human rights and international criminal law as we know it today. The definition of the crime of genocide, as defined in the Convention, has been widely adopted both nationally and internationally, including the Rome Statute of the International Criminal Court (ICC) of 1998. It is important that the Convention imposes an obligation on States Parties to take measures to prevent and punish the crime of genocide, including by enacting relevant legislation and punishing perpetrators, “whether they are leaders, civil servants or individuals responsible for the Constitution” (Article IV). This obligation, in addition to the prohibition refore of committing genocide, has been regarded as a standard of international customary law and is therefore binding on all States, whether or not they have ratified the Genocide Convention. Former Soviet prisoners of war and civilians repatriated from abroad were suspected of having been Nazi collaborators and 226,127 of them were sent to forced labour camps after being examined by the Soviet secret services of the NKVD. Many former prisoners of war and young civilians were also enlisted to serve in the Red Army. Others worked in working battalions to rebuild infrastructure destroyed during the war.
 All this was done outside the procedural framework of the Potsdam Conference of 1945. On this occasion, a Council of Foreign Ministers (United States, Soviet Union, United Kingdom, France and China) was formed to negotiate the various peace agreements, knowing that of the five countries that signed ceasefire agreements with the defeated nations, only those who had signed ceasefire agreements with the defeated nations would participate in the treaty negotiations (France is considered a signatory to a ceasefire with Italy). In principle, this should have excluded the United States from the peace agreement with Finland. In fact, all contracts with “axis satellites” were discussed by the Big Four (China). Numerous Council meetings were held in 1945 and 1946. They established five peace agreements signed by the US Secretary of State in Washington and other countries (Italy, Finland, Romania, Bulgaria and Hungary) on 10 February 1947 in Paris. The Senate approved it on June 4, 1947. The expulsion of ethnic Germans by the Poles concerned, in addition to the Germans in the areas behind the Polish border west of 1937 (as in most of the former Prussian province of West Prussia), the territories “under Polish administration” until a definitive peace treaty of Germany, i.e.
