There is no way that the U.S. was justified.
America was not justified in dropping the bomb. First off they had no idea how strong this bomb was or how much damage it would cause, they just decided to drop the bomb on a city filled with innocent children and people. I mean yes there had to be an end to the war but I feel like there was a better way of doing that. They could have figured out something other than blowing up Japan. There is no way that some one can honestly think that it is okay to kill thousands of innocent women, children,... People. They were all people. And the U.S. ended their lives just because they could. Innocent people didn't need to die to end the war. It just wasn't right and it wasn't necessary.
