Like mentioned before, a con is the amount of casualties the bomb will cause. Also, how much of the city will be destroyed. However, you also have to take into account the pros. A pro of dropping Little Man is that U.S. soldiers will not have to invade Japan. If United States troops invaded Japan, millions of lives would be lost. In addition to that, the U.S. is more vulnerable sue to low resources. I believe that if we invade Japan instead of dropping Little Man, we would lose the war. The United States losing the war would result in Hitler winning, which is everyone's least interest.
World War 2, is thought to a fight for humanity. Most people agree that if Hitler wins, that the world is going downhill from there. This is why the bombing has been justified. In my opinion, I believe that using nuclear weapons against Japan is necessary to end the war. If we do not drop the bomb, and we invade Japan instead, millions of soldiers will lose their lives. If we care about our country and our soldiers, we would choose to drop this
