Odd then that many others, including myself have not come to that conclusion. Cold-blooded revenge would have been better served by taking any of the other options. Ending the war as quickly as possible, was not revenge. Letting millions of Japanese starve would have been revenge. Continuing the bombing campaign of Japan until there was nothing left but rubble would have been revenge. Then again, where was this "revenge" after the war? In fact, there was very little of it...The Americans sent a vast number of stores to help Japan stave off famine. The Japanese were treated quite well by the occupying forces. The Emperor kept his head, neck, and life. Just the US showing off...Heck we were doing that when we announced US bombing raids of Japanese cities well in advance of the raid - and the Japanese still could not put up an adequate defense - Now, that is showing off.
