The Nagasaki bomb was, sadly, unnecessary. The Japanese had passed their intentions to capitulate through their supposedly neutral intermediary, the Soviet Union. The Russians sat on this information long enough to declare war on Japan and help themselves to some major spoils.

Something is wrong with this timeline. The Russians were at war with Japan at that time and were not neutral. It would make no sense for the Japanese to consider Russia as a neutral country between the dates of the Hiroshima and Nagasaki bombings, because Russia was already in combat with the Japanese army on the mainland. The overtures by Japan for ending the war were made through neutral countries like Sweden and Portugal, but were rejected by the US because there were always conditional terms attached. The US had made it very clear to all parties that only an unconditional surrender was acceptable.
