The predicted Allied casualties for a mainland invasion of Japan were so high, especially with regard to the civilian fanaticism witnessed throughout the Island-hopping Campaign, the right choice was using the Atomic Bomb. After use of the first atomic bomb, when Japan failed to yield and refused to surrender, the return to consideration to a homeland invasion, along with running the numbers of anticipated Allied casualties, made using the second Atomic Bomb the correct choice. The best choice was made, with regard to the information on hand at the time.
The atomic bomb is the last image is the reason we haven’t had a world war in 70 years. It has saved more lives that it took. It’s the reason you sleep safe in your bed at nights. It was essential in ending the war against the Axis. You guys need to be grateful.
