Nothing. Nothing at all. Just look at the modern equivalent: the USA's "missile shield" in Europe.
By the time of the Korean War, the Soviet Union had nuclear weapons and was allied with China and North Korea. Using a nuclear weapon there could have triggered a nuclear war between the US and the USSR.
The opposite side did win.
They would lose
Anything MIGHT have happened. You can speculate all you wish.
The Western Allies were able to reach Berlin at about the same time that the Soviets (Russians) did. Had the landing not been successful, the Russians (Soviets) may have taken the German Capital all by themselves. In which case, there might never have been a EAST and WEST Germany during the cold war.
You might see volcanic action.
Everytime one of their nuclear subs sank we had to help them recover lives, etc.; though they often politely declined our offer thru fear that we might see some of their military secrets...which was a fairly valid point.
They would have used them on both London and Moscow and might have won. This is why the Manhattan Project was necessary!
Because while we were supporting the south, the north were supported by the USSR, who also had nuclear missiles, and we didn't want to start a nuclear holocaust
Without a successful D-Day, there might never have been an East and West Germany during the cold war. The Russians (Soviets) would have controlled all of it.
