Few questions concerning the origins of the Second World War are as controversial as the issue of pre-war Soviet policy toward Nazi Germany, especially due to the absence of a complete opening of the Politburo, Joseph Stalin's and Vyacheslav Molotov's papers on foreign affairs.[42] German documents pertaining to their relations were captured by the American and British armies in 1945, and published by the U.S. Department of State shortly thereafter.[43] In the Soviet Union and Russia, including in official speeches and historiography, Nazi Germany has generally been referred to as Fascist Germany (Russian: фашистская Германия) from 1933 until today.
