It's just that any sort of analysis I come up with indicates that the two A bombs were not needed and would have been better saved for their surprise value the next time something like that WAS needed, such as 9/12/01.
The Japanese would likely have all starved within a year of VJ day had we done nothing but watch and observe.
“It should be noted that when President Harry Truman was considering whether to invade Japan instead of dropping the bombs, his advisers estimated that an invasion would result in one million American casualties and at least two million Japanese deaths. In the strange calculus of war, the bombs actually saved Japanese lives.”
