As for the cold war, if you consider the conflict USA-USSR they clearly won: Russia was, at least at some point, equally powerful to the USA technologically and militarly, what one did first, the other caught up pretty quickly, then the Soviet Government collapsed for various reasons, and they couldn’t catch up, now the USA is arguably the most technologically advanced country in the world, in many aspects.
