Many people acknowledge the terror of Atomic bombs as an idea. People who actually were under the bombs do know, from deep inside their bones, (deep inside their heart) that such things must not be used again. These people are not involved in any anti-nuclear power movement.
No matter what the context is, using atomic bombs should not be taken as a way of a solution. However, the fact is that the action was taken. I hope that the anti-nuclear power movement will be the one that understands the truth.
