In May 2009, Medvedev set up the Presidential Commission of the Russian Federation to Counter Attempts to Falsify History to the Detriment of Russia's Interests. In August of the same year, he stated that he opposes the equating of Stalinism with Nazism. Medvedev denied the involvement of the Soviet Union in the Soviet invasion of Poland together with Nazi Germany. Arguments of the European Union and of the OSCE were called a lie. Medvedev said it was Joseph Stalin who in fact "ultimately saved Europe".
