Fantastic post 81alum.
I have not done a done of reading on this subject but from Toland's Rising Sun, it's clear the Japanese domestic governance by summer 45 was chaotic, but the groups that advocated fighting on would probably have not been able to outmaneuver an Emperor set on a certain course of action. The bomb probably was not necessary to end the war without an invasion of the home islands, if the US wanted to go that route, and signaled appropriately to the Japanese that surrender while allowing the continuance of the Imperial family was acceptable.
The bomb was dropped because we made it, and Groves was always going to drop it once we had it. Truman was almost a secondary figure in it's deployment. I don't think it was really a demonstration to the Soviets as a discrete and thought out piece of foreign policy.
