There was an agreement during world war two that the Soviets would declare war on the Japanese when the german issue was dealt with. With the defeat of Germany the soviets renegged on this deal and did not declare war on the Japanese empire, or send troops or intelligence. When the soviets demanded that Korea be split in half and Manchuria hand over to soviet adminstration Truman was ready to tell them to go to hell.

The compromise led to Manchuria being handed over and the US adminstrating the whole of Korea, some credit this decision as being the event that led to the cold war, some say that the cold war was envitable, but what if the Russians had honored their promise to declare war on Japan how would the world look today.
