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.

That's one of the major lessons: no president should ever take this nation to war without full public debate in the Congress and/or in the public.

Action should be founded on contemplation, and those of us who act don't put enough time, don't give enough emphasis, to contemplation.

Rationality will not save us.

The indefinite combination of human fallibility and nuclear weapons will lead to the destruction of nations.

I would characterize current US nuclear weapons policy as immoral, illegal, militarily unnecessary, and dreadfully dangerous
