World War I broke out largely because of an arms race, and World War II because of the lack of an arms race.
Only those who are ideologically opposed to military programs think of the defense budget as the first and best place to get resources for social welfare needs.
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.
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.
From a scientific perspective there is some indication that a nuclear war could deplete the earth's ozone layer or, less likely, could bring on a new Ice Age - but there is no suggestion that either the created order or mankind would be destroyed in the process.
For if enough people were really convinced that growth should be halted, and if they acted on that conviction, then billions of others might be deprived of any realistic hope of gaining the opportunities now enjoyed by the more fortunate.

To the extent that these advanced weapons or their components are treated as articles of commerce, perhaps for peaceful uses as in the Plowshare program, their cost would be well within the resources available to many large private organizations.
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 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.

A surprising number of government committees will make important decisions on fundamental matters with less attention than each individual would give to buying a suit.
Failures of perspective in decision-making can be due to aspects of the social utility paradox, but more often result from simple mistakes caused by inadequate thought.
Anything that reduces war-related destruction should not be considered altogether immoral.
