I want to say, and this is very important: at the end we lucked out. It was luck that prevented nuclear war. We came that close to nuclear war at the end. Rational individuals: Kennedy was rational; Khrushchev was rational; Castro was rational. Rational individuals came that close to total destruction of their societies. And that danger exists today.
Robert McNamara...but highly placed sources within the Kennedy Administration disagreed: "[T]he assumption that the strategic nuclear balance mattered in any way was wrong... As far as I am concerned, it made no difference... If my memory serves me correctly, we had some five thousand strategic nuclear warheads as against t heir three hundred. Can anyone seriously tell me that their having three hundred and forty would have made any difference? The military balance wasn't changed. I didn't believe it then, and I don't believe it now..."
