With biggest respect to 400k victims of WWII from USA as well as to all victims, killed during this terrible War by German NAZI.
The Truth is:Russia Saved Europe by burying Hitler in Berlin.
Russia Saved America from Japan by beating Japan on Continents in China, Kurills, where allies never knew how to fight.
Role of Americans: Opening the Second Front in VERY end of 1944 for Collection of Gold, Arts and NAZI Technologies, Man Power, including Nuclear and Missile Know-How, while Russians were fighting with NAZI face to face.
God, save Russia from having such allies once more! They are worse than enemies, and are always looking for stabbing You from back.
