"All sorts of alternate history stories could be written from this point."

True, but in none of them would we have lost the war.
There was a courage and determination in America at that time that seems rather lacking now, and far from demoralizing us, a nuclear attack on San Francisco would most likely have spelled the end of the Japanese race.

I don't think we would have stopped at dropping only two of the big bombs on them.
I don't think we would have stopped until we ran out of uranium.

Also true ... I don't think that, in our real history, that we should have stopped when we did. Particularly, one of the initial targets should have been Tokyo.

The second, Moscow ...

Ooops ... wrong history.

I seem to recall reading that the three bombs detonated by the US were the entire supply, and it took a few months to build any additional ones. In a sense, dropping the last nuke only a couple days after the previous one was a bluff.

And just how many bombs do you think we had?
