The widespread diffusion of nuclear weapons would make many nations able, and in some cases also create the pressure, to aggravate an on-going crisis, or even touch off a war between two other powers for purposes of their own.

As for total disarmament, there are almost 50,000 nuclear weapons in the world today; even if they were banned, not all would be destroyed.

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.

Failures of perspective in decision-making can be due to aspects of the social utility paradox, but more often result from simple mistakes caused by inadequate thought.

Many people believe that the current system must inevitably end in total annihilation. They reject, sometimes very emotionally, any attempts to analyze this notion.

Risk-taking is the essence of innovation.
