well, aside from that, he acted in a rational way when when everything else was telling him to do the opposite. If there had been no person behind the decision to launch nukes, if the job had been assigned to be automatically done by a computer, well, we wouldn't be here. Only a rational and calm person could make the judgement "gee, all the senors are saying something, but there is no good reason why anyone would launch nukes out of the blue, so I'll declare this a false alarm".
I suspect that if it had been the other way around, if some jumpy, panic-striken guy at NORAD had seen Russian nukes headed for New York, things would have gone quite differently.
