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

New developments in weapon systems during the 1950s and early 1960s created a situation that was most dangerous, and even conducive to accidental war.

Hopefully, nations will refuse to accept a situation in which nuclear accidents actually do occur, and, if at all possible, they will do something to correct a system which makes them likely.

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.

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.

Projecting a persuasive image of a desirable and practical future is extremely important to high morale, to dynamism, to consensus, and in general to help the wheels of society turn smoothly.

Many people believe that the current system must inevitably end in total annihilation. They reject, sometimes very emotionally, any attempts to analyze this notion.
