Dropping the bomb was the right decision.
63 years ago today over the city of Nagasaki a plutonium bomb was used.
Due to some topographical quirks (there were no large hills as in Hiroshima to focus the blast effect), the casualty rate was lower. Still, Fat Man managed to kill more than 40,000 that day and another 40,000 before that fateful year faded into history.
The war with Japan, with its racial overtones on both sides as well as the undeniable cruelty and barbarity by the Japanese military, should have been ended the second it was possible to do so.
Anything less makes the moral arguments surrounding the use of the atomic bomb an exercise in sophistry.
