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.

I'm against fashionable thinking.

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.

It is immoral from almost any point of view to refuse to defend yourself and others from very grave and terrible threats, even as there are limits to the means that can be used in such defense.

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.

I'm against ignorance. I'm against sloppy, emotional thinking. I'm against fashionable thinking. I am against the whole cliché of the moment.

Human and moral factors must always be considered. They must never be missing from policies and from public discussion.
