A group of nearly 60 scientists announced Tuesday open letter to the President of Ukraine Petro Poroshenko, which agitates him not to sign adopted by the Verkhovna Rada of Ukraine laws banning Communist symbols and the glorification of organizations of Ukrainian nationalists. An open letter signed by more than 50 researchers from the USA, Canada, Germany, UK, Sweden, Turkey, and several scientists from Ukraine and one from Russia. The Verkhovna Rada had passed a law banning the Communist and the national socialist (Nazi) totalitarian regimes in Ukraine and Their symbolism. Also, a law was passed declaring " the Organization of Ukrainian nationalists and the Ukrainian insurgent Army (UPA) fighters for independence of Ukraine in the twentieth century and provide its members the right to social guarantees. "As scientists and professionals who are striving for the revival and freedom of Ukraine, we believe these laws are a bad omen. Their spirit and content contradicts one of the basic political rights - the right to freedom of expression. Their adoption will raise serious questions about the extent to which Ukraine committed to the principles of the Council of Europe and OSCE, as well as a number of treaties and declarations adopted since Ukraine gained independence in 1991, " - said in a statement. In addition, the laws will have a negative impact on image and reputation of Ukraine in the EU and North America, will assist those who wish to the weakening of Ukraine, scientists say. "The potential impact of both laws scare us. According to them it would be a crime to cast doubt on the legitimacy of the Organization (UPA), which massacred tens of thousands of poles in the process one of the most heinous acts of ethnic cleansing in the history of Ukraine. It also exempts from opponents of the OUN, one of the most extreme political groups in Western Ukraine in the interwar period, who collaborated with Nazi Germany after its invasion of the USSR. She (OUN) Also participated in the Jewish pogroms in Ukraine and, in the case of a fraction of a Miller, was an ally of the occupation regime throughout the war, " - said in an open letter. "However noble, would be the goal, sweeping condemnation of the entire Soviet period As a period of occupation of Ukraine will be unfair, illogical consequences. All who drew attention to the development of Ukrainian culture and language in the 1920-ies, will be condemned. It's about those who will consider the Gorbachev period As a progressive period of change, which helped the society, informal movements and political parties in Ukraine, including the "people's movement," according to scientists. They blame the Russian Federation in that It is engaged in "the politicization of history" and warned Ukraine against similar actions. "Any legislative or administrative distortion of history Is an attack on the underlying goal of all scientific research: the search for truth. Any official attack on the historical memory of injustice " - said in an open letter. While scientists believe that deserve respect As Those Ukrainians who fought against Nazism, and Those who were against communism." Half a million Ukrainians who died fighting the Nazis in the red Army, worthy of respect As Those who fought with the red Army and the NKVD. Those who believe the victory over Nazi Germany a key historical event, can not feel humiliated and be expelled from the nation, " - said in the letter. The Supreme court of the Russian Federation in November 2014 was included in the list of extremist organizations "Right sector" Ukrainian national Assembly - Ukrainian national self-defense "(UNA-UNSO), the Ukrainian Organization "Brotherhood" and "Trident behalf of Stepan Bandera and the Ukrainian insurgent army" (UPA).
