The Yeghern – Genocide of Armenians in their homeland – has relatively recently become an object of political debate after decades-long silence. The already revealed facts of the universal evil, concepts and definitions shaping the public perception, among them the widely held and publicized formula of “The Armenian Genocide in the Ottoman Empire in 1915-1923” which does not correspond to the factual and political content of this crime against humanity, await new interpretation. To this day the Genocide of the Armenians of Eastern Transcaucasia remains outside the Turkish crime. Consequences of the international political implications of Yeghern, as well as the irresponsibility of world powers as the main guarantors of international security, have not been adequately evaluated, and this is sure to lead to the establishment of new genocidogenic states and the legalization of criminal behaviour.
