Hopefully, nations will refuse to accept a situation in which nuclear accidents actually do occur, and, if at all possible, they will do something to correct a system which makes them likely.

In a world which is armed to its teeth with nuclear weapons, every quarrel or difference of opinion may lead to violence of a kind quite different from what is possible today.

For some years I have spent my time on exactly these questions - both in thinking about ways to prevent war, and in thinking about how to fight, survive, and terminate a war, should it occur.

A healthy and fully functioning society must allocate its resources among a variety of competing interests, all of which are more or less valid but none of which should take precedence over national security.

Nuclear weapons are intrinsically neither moral nor immoral, though they are more prone to immoral use than most weapons.

Deterrence itself is not a preeminent value; the primary values are safety and morality.

My guess is that nuclear weapons will be used sometime in the next hundred years, but that their use is much more likely to be small and limited than widespread and unconstrained.
