Help on a question

I have to write an essay about dropping the atomic bomb on Hiroshima and Nagasaki. I have a good start, but I was wondering if you guys could help a little. I just need a few points on this part of the question. “Did military necessity outweigh the humanitarian and moral objections to the use of this weapon?”
Just a few points so I have more to work on. You don’t need to go into detail, just basic points.
Thanks!</p>

Potsdam, yalta conferences. D day. Unconditional surrender. Stalin joining the war against Japan. Iwo jima. Casablanca. Leapfrogging. Liberating France. </p>
