Why was it not necessary for the US to drop the atomic bomb?

Yes!! It was nessasary because if we did not, they would not have surrendered!!!! We ended the war. It FORCED Japan to surrender due to all the deaths and war cost that would have had to be payed if any more was damaged.

It was entirely unnecessary. Japan was ready to surrender, but we were pushing them to surrender unconditionally. They thought that meant we wanted to depose their emperor, whom they believed was a descendent of their sun goddess, and they could not let that happen. If we had just let them have that condition, we would not have "had" to commit the unspeakable horrors that took place.

Of course it was neccesary. Basically, a land invasion would've cost waaay more lives than the nuclear bombs did. So all of you who thinks US is a scumbag country, fawk off. They did just the right thing. The japs were warned before both bombs. They were told to surrender, and they didn't. So they got it the hard way, in the least devastating one.
