It wasn't a belief that Japan would surrender. Russia had moved east and was beginning to invade the Japanese islands in an effort to end the war, and Japan was weakly staffed on that end of the nation. It was a choice of surrendering to either the US or the USSR. They chose the US b/c they believed we'd allow them to retain much of their gov't, which we did. (Incl war criminals).

We dropped those bombs to stop Russia.
