The difference between the US having atomic weapons and other nations having them (such as Pakistan, India, Iraq, Iran, Israel, Palestine, etc.) is that the US will not use them nowadays, but those other nations will not hesitate to use them on their hated neighbors. Well... they will hesitate, but only because the US will most likely step in to the conflict to stop further use of the bombs. This is why the US tries to prevent other nations from developing them. There is no good reason for them to develop them.

There is 0 doubt that the US using the atomic bombs on Japan saved millions of lives. The Japanese had foguht very very resiliantly, most often to the Last man standing, on every minor little island that the US liberated from their occupation in the Pacific. Imagine how they would have fought to defend their home islands.
