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.

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.

There was no race - but to the extent that there was an arms competition, it was almost entirely on the Soviet side, first to catch up and then to surpass the Americans.

Risk-taking is the essence of innovation.

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.

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