Tomiko Morimoto was only a 13-year-old school girl at the time of the explosion of "Little Boy". Her city, Hiroshima, had never been bombed before and when she heard the lone B-29 droning overhead, she didn't pay much attention to it, until she saw the explosion. Next came the loud sound which was deafening, and finally she became aware of the destruction around her. Buildings were uprooted and windows broke, it was chaos.
Morimoto's instinct was to run then and there, and as she raced as far as she could from that fireball behind her, she saw black rain falling down, and she thought it was oil that the Americans were using to burn her to death...

That was what happened to many citizens of Hiroshima and Nagasaki when hell was introduced to their city, some of the unfortunate ones never made out alive as their burning skin finally killed them. Yet, they have never fought in the war and probably never killed something larger than an ant. These people certainly didn't deserve the atomic bomb, but that is history and fortunately for us, people learn from history. We should never forget what these innocent people have been through or have become when the atomic bomb hit their city. We are very lucky today that no other nuclear bomb has ever been used on civilians again.
