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

I am against the whole cliche of the moment.

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

Risk-taking is the essence of innovation.

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.

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

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.
