Coming to agreement on whether it was "necessary or not" would require agreeing on what the necessary outcome of the war had to be... and we see that very differently than the japanese, and we always will. If all that was to be accomplished was to temporarily stop Japanese aggression in the Pacific, then we had pretty much assured that by the time we had the A-bomb. But, the only outcome which the allies would accept was unconditional surrender, assuring that Japan would suffer a defeat of sufficient humiliation to make sure they never considered a similar action in the future. Such is the end of all wars... those who believe they were wronged never settle for anything less than unconditional surrender, true even when the United States fought itself in our own civil war. One point which is clear: Japan would NEVER have surrendered without dropping the bombs and many in the regime fought hard against surrender even after they were dropped.
I disagree. Dont get me wrong. I like the outcome of the war. My point was that your sources could be wrong. If the japanese indeed were ready to surrender without the bombs the outcome would be the same without such drastic measures. The point which is clear for you is exactly the one which I think is impossible to be sure of.
In a war of attrition, with artificial rules imposed by you, where we take one life from them for every life they take from us...they win handily.
I get it finally.. a little embarrassed, but amused.
