The port cities of Hiroshima and Nagasaki were nuclear-bombed to stop the War without invading Japan (Which was about ready to be done when the bombs were dropped) which saved millions of Allied and Japanese lives. A number of Japanese Navy officers after the Japanese surrender expressed their approval, as their Army was not about to surrender until everyone in Japan was dead. A lot of people do not realize that many more Japanese were killed in the ongoing bombing of Tokyo with conventional weapons, than were killed by both nuclear bombs.
It was the other way around. Albert Einstein and another physicist influenced World War 2 when he wrote a letter to President Roosevelt telling him that the Germans were starting on an atom bomb. He suggested the US get an atom bomb made to stop the German Nazis. Roosevelt and his committee chose to follow Einstein's advice and the Manhattan Project was created as well as three atom bombs. However, Einstein disliked the thought of nuclear bombs being made and used. He knew the devastation it would cause. He also was leary of Humans using nuclear physics to create anything.
When the Air Raid sirens stop and the bombs stop falling it is safe to leave.
