Why did the US not trust the Soviet Union?

Explanation:

The United States felt that they had been betrayed by the Soviet Union when the Soviet decided to be self-preserving instead of acting like the ally they were supposed to be according to the idea within the Yalta agreement. Beyond the Yalta agreement turmoil, the United States found evidence that they Soviet Union had been spying on them during the time they were supposed to have been allies. In the end, both side lost trust in each other and became enemies.

The Soviet Union's proclaimed goal was worldwide communism. Due to this, there had been no trust from the start between the two countries. The Soviet Union was not included in the American/British creation of the atomic bomb during the Second World War. They felt they were doing their part in the alliance and did not like being left out of something so important. This helped to further cement distrust.
