The Atomic Bombs: Were They Justified?

I agree with the one opinion that the bomb we dropped on Nagasaki was unjust because we already made out statement that the war was done.  The first bomb dropped in Hiroshima, that was just because it was are way saying we are done and you are defenseless; we needed to end this war on top and not at the bottom.  Some say that it wasn't fair that we dropped the bombs in an area that wasn't Anglo-American but I believe that it was fair.  They were the reason we entered the war after they attacked Pearl Harbor, so that's why its fair.  The only thing that makes me feel like both the bombs were unjustified was the fact that it killed so many more people on top of the people already lost during the war.  But I guess we just had to go out with a boom.
