During the Christmas party, the Russian judge, Gen. Iona T. Nikitchenko states that 20 million Russians died during the war. Three months later in March 1946, during an official interview with the Russian newspaper "Pravda", Joseph Stalin stated that the official death count was only seven million. The 20-million death toll wasn't admitted to until 1956: Premier Nikita Khrushchev gave that total to a Communist Party congress meeting in Moscow. In 1989 during the Mikhail Gorbachev "Glasnost" era, the total deaths were then reported to be 27 million. With the fall of the Soviet Union in 1991, the state archives were opened to research by private historians: the death toll was stated to be as high as 35 to 42 million but not recognized by the state. The research by private academics has caused the state to again shut down the archives.
