My understanding is the USA could have produced maybe 9 nuclear bombs per year in 1945 and some of them would possibly be duds. The plutonium production just wasn't there.

America's strength after slaughtering innocent people in Japan was no other country quite knew how much plutonium America could produce, or how many bombs had been manufactured. The two dropped on Japan were the only two America had. Eisenhower had wanted to immediately nuke Moscow, but what would that have really done? I don't know if that would have resulted in complete American domination, it probably would have led to complete global panic, including panic within the USA. There would have been immediate widespread terrorism throughout the world probably. It's hard for me to imagine what kind of world that would have been because of how unstable it would be. No one would trust the USA. One of the western countries like the UK or France or something might try assassinating Truman, or stealing nuke design documents. It wouldn't have been normal. Whatever was left of the USSR would have possibly tried a hot war with the US, and how would that have gone down? Imagine exactly one US city getting firebombed. Imagine San Fransisco getting bombed. Would Americans in 1945 just deal with it because there's a war now? I doubt it.

This also makes no sense because Stalin did rebuild eastern Europe after WW2.
