I'm against fashionable thinking.

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

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.

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.

It may literally turn out that a Hottentot, an educated and literate Hottentot it is true, but one who is a member of a relatively primitive society, would be able to make bombs.

Nevertheless, during the sixty years of the twentieth century many problems have come increasingly into the realm of acceptable public discussion.

Risk-taking is the essence of innovation.
