Some of what you say makes sense such as the U.S. being tired of war but some of it is more nonsense than some of the conspiracy stuff.
I just glanced at my world map and the distance from much of Europe to Moscow was quite a bit shorter than from Tinian to Tokyo. B-29’s could easily have made the round trip and escorted at that.
With atomic weapons we could have told Stalin to get out of town before sundown and he would have had no other choice but to do it. That is if he did not have spies in our government who would have assured him we would never do it.
Big difference. The Japanese had no more fighters. But to cross Europe to Moscow??? Fuggedabout it. We would have encountered hordes of Soviet planes the whole way-—and remember, the weight of the Bomb was so great that I don’t think you could carry more than one per plane, meaning every plane that went down was a complete loss to our nuke arsenal. Then there were the duds. As late as the 1970s, a full 15% of our rockets and bombs failed (this is actually pretty low). But still, take a 100 plane raid, spruce it up with 100 decoys, then siphon out 15% duds, then apply Soviet air defenses . . . .? Nope, wouldn’t be sufficient to even make a dent in Soviet ground capabilities.
And let me again refer you to THE book on the subject by Col Harry Borowski, “Hollow Threat.”
