World War I broke out largely because of an arms race, and World War II because of the lack of an arms race.

In 1960 I published a book that attempted to direct attention to the possibility of a thermonuclear war, to ways of reducing the likelihood of such a war, and to methods for coping with the consequences should war occur despite our efforts to avoid it.

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.

Nuclear war is such an emotional subject that many people see the weapons themselves as the common enemy of humanity.

Anything that reduces war-related destruction should not be considered altogether immoral.
