I don't know...I think that it is just too likely for governments to think that an atomic bomb is just a big bang when they are on the technological horizon. I can't see them really grokking the radiation, the scores of thousands of massive burn victims, the rubble stretching to the horizon...they will have a head knowledge, not a gut or heart knowledge. It will simply be too tempting to use them in war, until, like a child, they find out how much fire can hurt.
