> It's not a given that it did not end... think to yourself what would happen if Nazi Germany had developed a nuclear bomb ahead of the Americans?
Nukes at the time were still weak weapons. You could inflict a lot more damage (and a lot more damage happened on Tokyo and many other Japanese cities) by regular firebombing. You did not need nuclear bombs to inflict catastrophic loss of life.
Now when it came to thermonuclear weapons, the magnitude is entirely different, but that only occurred many years later. It would never have occurred at the time of WW2.
