Well, (I'll try to stay neutral with this) the US was staying out of World War 2, mostly, but Japan attacked Pearl Harbor before declaring war with the US, causing the US to join the war and fight them.
The war was mostly over, Germany had surrendered, but Japan hadn't. For some reason or another, I think it was because they didn't want to lose a bunch of troops trying to fly out and take Japan, the US dropped the atomic bomb. They then asked for Japan to surrender, and they told them they had another bomb, but Japan didn't, maybe they thought the US was bluffing or something, but the US dropped the second bomb and eventually Japan surrendered.
Sorry it's kinda long, but that's the best way I can explain it.

Japan.
No, America only dropped the atomic bombs on Japan.
Hiroshima and Nagasaki(atomic bomb,not a nuke)
After Pearl Harbor, America was devastated. In an attempt to end the war, they used the atomic bomb against Japan. It worked.
They had 85 allies.
