It was actually known to the US Intelligence and their top brass (and I mean TOP) at the time that Japan was on the brink of surrender, only after the bombs were dropped was there a coup attempt to stop just that.
Even Eisenhower believed it and many others believed the bombs to be an atrocity, General MacArthur wasn't even consulted.
The nukes may have lead to the end of the war, but they were neither necessary nor justifiable.
I have always felt the justification for the bombings to be "Complex" :/
#1 The USA spent more on the Atom bomb project than Germany spent on rocketry! they produced the grand total of three "Gadgets" (One test, two actual Bombs)
One might argue that after all that expense it might have been politically /scientifically inconceivable that they wouldn't actually have used them!
(Indeed, Hiroshima and Nagasaki were specifically designated as "Protected" targets much earlier in the war because hitherto "Undamaged" targets were required in order to assess the damage that Nuclear munitions might actually produce. )
#2 OTOH, Invading Japan would have been truly horrendous! merely considering huge casualties doesn't come close to what would actually have been involved! (The US military would never have been able to allow its "Japan Vets" to de-mob!) Nuking Japan into submission from a distance was the only realistic alternative! (#)
(#If you haven't already got the point, it was to protect the GI's, not the Japs! and I am not talking about mere death and injury here!)
And that's only two aspects of it!
Im a bit ****ed now and going to bed.

If anybody wants to take me up on this please feel free,

But I wont reply till tomorrow.
G'night all!
