Side issue: should the military effectiveness of bombs be measured by the death toll?

I tentatively suggest that atomic and nuclear bombs are of a different kind than chemical explosives, as shown by the former changing the world politically.

I'm not sure exactly why-- it may have been the shock of novelty.

Atom and nuclear bombs combine explosion, fire, and poison, but I see no reason to think there would have have been the same sort of wide spread revulsion against chemical explosives, and the world outlawed poison gas in WWI and just kept on going with chemical explosives.
