Um... it's somewhat more complicated than that. During the World War II, there were quite a lot of tension between the nations. Russia had suffered a great deal of casualties compared to the USA. I believe it was something like 60 times the casualties of American military. As a result, the Soviets made sure that they would never be invaded again or weakened by any other rivals.
Also, all of the other rivals were greatly weakened or destroyed in the war. The USA and the Soviets were the remaining superpower countries. So it was hardly a surprise that the USA and Soviets became enemies. The Cold War has a complicated history, the history textbooks in both countries are grossly slanted.
