Relations between the Soviet Union and America deteriorated almost immediately following Germany's surrender. Or are you talking about Détente or the 90s and early 00s? In the former case, the two sides were still overtly postured for war with each other. In the later case, the apparent "warm relations" were little more than the Russia being in such a disorganized state that the only thing they could really accomplish was the accepting of western investment/bribes. Not exactly a healthy relationship.
