Your question does not make sense. The Soviets drove the Germans out and back to Berlin and saved everyone's necks in Europe. What sins? The U.S. should repent for its sins against the common man.

You don't completely and fundamentaly change the system of government in a country for a"ruse". That would be incredibly impractical.
