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

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.

Because of new technologies, new wealth, new conditions of domestic life and of international relations, unprecedented criteria and issues are coming up for national decision.

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

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.

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.

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