Knowledge or no knowledge, the intelligence community is obliged to furnish estimates to military planners, even if they’re worthless and very possib… - Samuel T. Cohen

The briefing was over, there were lots of questions that Teller handled with aplomb, knowing far more about the subject than most in the audience. Finally there came a question that had nothing to do with whether or not his bomb was feasible. Instead, it was whether it would destroy the world by causing uncontrollable thermonuclear reactions in the earth’s atmosphere that would cause it to burn up, plus you and me and everyone else. Teller was on his game, as he always was, and replied that he had estimated this terrible possibility and we were quite safe — by about a factor of ten. Now there aren’t too many people who rest comfortably with assurances that mankind’s fate, let alone their own, is on the safe side by a factor of ten, although there are millions of smokers, including myself, drug addicts, sex addicts, who take much greater chances than that with their lives, and they know it. Except that they know it won’t happen to them, which is why many soldiers, at least as stupid as they’re brave, get Congressional Medals of Honor.

The next day, I called one of them and asked if I could come to his office to discuss the briefing. Fine with him, so off I went. I sat down and asked him a question: “Norm, how did you decide so exactly where the bomb would explode?” He looked at me as if I were a country bumpkin and explained how SAC calculated its bombing accuracy and he had gotten the accuracy of this particular drop straight from the horse’s mouth. Now I don’t want to bore you with how SAC arrived at planning estimates for the delivery accuracy of its nuclear bombers, except to say that it was a statistical process based on thousands of practice sorties, whose results would be mathematically analyzed to allow estimates to be made of the results of a large bombing campaign; not one bomber flying over one city and one bombardier, with the lives of perhaps millions of Muscovites at his fingertips, dropping one bomb. This I pointed out to Norm, implying that he had gone to all that fuss and bother for naught. His response was that in doing his calculations as a mathematician, he was going by the accepted ground rules. The bombing accuracy he had assumed had been provided to him by others. His was not to reason why.

He was all in favor of fighting an all-out thermonuclear war that might devastate a fair fraction of civilization, to settle an argument with the USSR, but was dead set against using discriminate nuclear weapons that could settle arguments on the battlefield without devastating everything in sight. Genius, when applied to human problems, can manifest itself in strange ways.
