In 9th grade US history we held a mock trial about the nuclear strikes on Hiroshima and Nagasaki. I was assigned the role of Harry Truman, one of the defendants. I did a ton of research about the plans for invasion of Japan on both sides, and it was terrifying. The Japanese were teaching children to fight with garden tools, and US casualty estimates were over a million soldiers.

However, in the end I came to the conclusion that the nuclear strikes weren't necessary, and I wouldn't have ordered them simply because a the war was already incredibly one-sided, and an invasion wouldn't have been necessary in the first place since Japan was already on its last legs.

The class ended up convicting me of a war crime, which was nice.

Then how does the war end, in your scenario?

The US accepts Japan’s conditional surrender, the one that Japan was sending in hopes that the US would offer them a better deal now than after the USSR finished kicking them off the mainland.
