"The idea that Japan was on the edge of giving in and was about to wave a white flag isn't born out by the evidence."
That's not an idea I've expressed.
I think you may have lost track of the context of this exchange. I'm familiar with the broad lines of the question of the planned invasion, and when you referenced it before I didn't object to your presentation of it, itself*. I just mentionned the doctrine of unconditional surrender, which is something that belongs to the portion of the context of these Historical event that is convenient to ignore when the extremely common place argument about the hypothetical invasion of Japan is brought out.
Now instead it seems that you might be trying to convinced either Ted Knight or Leo Szilard of the righteousness of the use of the bombs. They're both dead and one's fictional, I'm afraid, and arguing with me over this won't make the view of the latter (and the similar view that Ted Knight was portrayed with) anachronistic. Which was my main point in commenting.
*I'd be out of my depths in military matters, in any case.
