America largely resolved these contradictions by abandoning the Truman Doctrine - in favor of creating client states (which had the added benefit of being a huge profit source to the American arms industry) and by suggesting that the USSR had somehow abandoned the agreed-upon mission of the Nuremberg System - this is what really underlay the Helsinki Accords (why the DDR and the USSR put a premium on such political theater I mean) and why Gorbachev was so resistant to demands by men in the Soviet security apparatus to enforce the Breznhev Doctrine as the internal situation became critical in 1989 - the conceptual/intellectual climate of 1949-1989 remained grounded in the ideology of Anti-Fascism; and the Eastern Bloc and the United States/NATO busily set about accusing one another of behaving in a demonstrably ''Fascist'' manner each and every time the Cold War actually became ''hot'' in various contested theaters.
Had World War 3 happened, Hitler would have remained the model for Satan - the proximate cause of the conflict would have been identified as rogue elements in the US and Soviet regimes (Fascist elements, in other words) succeeding in their evil machinations by provoking a world war.
