I don't see the point of the discussion of the moral correctness of the A-bomb
as used on Japan in the second war.
Why? Even counting delayed death to radiation related causes, I think many, many more people were killed in conventional (fire) bombing of cities across Japan. If they didn't drop the A-bombs, they probably would have continued the large-scale bombing raids to the same effect, just over a longer time.
IMO, a discussion more relevant to human suffering would be about the mass bombing of civilian population, regardless of the weapon type. That's not to say that A-bombs aren't worth talking about, I am just puzzled as to why they're talked about as the cruellest thing the west did to Japan, when the numbers say otherwise.
Willing to discuss, of course
