I think this nuclear saved lot of civilians too. If war is between Army its ok but when it becomes civilians it harms society. Germany and Japan have started killing civilians and therefore they deserve it. Although Germany would deserve it more, but it was just unfortunate that Japan got the worst gift. If some consider Japan was good then its not true. They were using Comfort Women for their satisfaction. They were not man they were worst and two bombs made them man. If Japan could have nuclear tech, America would have been wiped out.
The worst Enemies of the century America and Japan are now the best Friend of 21st century. So, Fights and Friendship are not static.
