RetiredGySgt, in a rather lazy fashion repeatedly points to
The National Security Archive 's collection of
77 documents on the atomic bomb and end of world war 2 saying 'the proof is in there'. Rather like tossing a dictionary at a newspaper editor and saying 'here's tomorrow's front page story'.
So where in the comprehensive 77 lengthy sections could that magical, much sought-after golden fleece-like 'good reason' to consign the 350,000 civilian population of Hiroshima and the 250.000 civilian population of Nagasaki to the horrors of a nuclear blood bath be hiding?
Perhaps it was Document 29, where on 11 of July Foreign Minister Togo sent the following 'extremely urgent' message to Ambassador Sato:
"We are now secretly giving consideration to the termination of the war because of the pressing situation which confronts Japan both at home and abroad Therefore, when you have your interview with Molotov [ in accordance with previous instructions] you should not confine yourself to the objective of a rapprochement between Russia and Japan but should also sound him out on the extent to which it is possible to make use of Russia in ending the war."
and then on the same day:
".. Japan- as a proposal for ending the war and because of her concern for the establishment and maintenance of lasting peace - has absolutely no idea of annexing or holding the territories which she occupied during the war."

These Documents reveal many desperate attempts by Japans envoys to establish a surrender up to the very end and on August 5th (Document 52). All the while U.S. interceptors secretly listened in, and made Truman's office aware of the full content of these Japanese attempts yet they went ahead anyway, choosing to test one of each type of their new atomic devices, first Uranium, then Plutonium on the living Human guinea pigs; the old men, the helpless women and innocent children behind enemy lines, away from the theatre of war, away from where the soldiers were. America sneaked in, from a safe height and in cowards fashion dropped their devastating bombs on non combatants then ran away.
And as President Harry Truman ate his lunch on the Augusta with fellow mass murderers Winston Churchill and Joseph Stalin, news of the bombing of Hiroshima came in. Jubilantly, he announced to the retinue of sailors around him..
"This is the Greatest thing in History!"
