Seventy-five years ago white slavery was rampant in England. Each year thousands of young girls were forced into brothels and kept there against their will. While some of the victims had been sold by their families, a large proportion were seized and held by force or fraud. The victims were not from the lower classes only; no level of English society was immune to having its daughters seized. Because this practice continued in England for years after it had been largely wiped out on the Continent, thousands of English girls were shipped across the Channel to supply the brothels of Europe. One reason why this lasted as long as it did was that it could not be talked about openly in Victorian England; moral standards as to subjects of discussion made it difficult to arouse the community to necessary action. Moreover, the extreme innocence considered appropriate for English girls made them easy victims, helpless to cope with the situations in which they were trapped. Victorian standards, besides perpetuating the white slave trade, intensified the damage to those involved. Social inhibitions which reinforce natural tendencies to avoid thinking about unpleasant subjects are hardly uncommon.

The psychological factors involved in ostrich-like behavior have parallels in communities and nations. Nevertheless, during the sixty years of the twentieth century many problems have come increasingly into the realm of acceptable public discussion. Among various unmentionable diseases, tuberculosis has lost almost all taint of impropriety; and venereal disease statistics can now be reported by the press. Mental illness is more and more regarded as unfortunate instead of shameful. The word “cancer” has lost its stigma, although the horror of the disease has been only partially abated by medical progress.

Despite the progress in removing barriers in the way of discussing diseases formerly considered shameful, there are doubtless thousands going without vital medical treatment today because of their inhibitions against learning, thinking, or talking about certain diseases. Some will not get treatment because they do not know enough to recognize the symptoms, some because they are consciously ashamed to reveal illness, and some because they refuse to think about their condition— it seems too horrible to think about. It may now be possible to condemn unequivocally the extremes of Victorian prudery, but less doctrinaire forms of ostracism must be considered with more care; they are, after all, often based on healthy instincts. Everyone is going to die, but surely it is a good thing that few of us spend much time dwelling on that fact. Life would be nearly impossible if we did. If thinking about something bad will not improve it, it is often better not to think about it. Perhaps some evils can be avoided or reduced if people do not think or talk about them. But when our reluctance to consider danger brings danger nearer, repression has gone too far.

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. The book was greeted by a large range of responses— some of them sharply critical. Some of this criticism was substantive, touching on greater or smaller questions of strategy, policy, or research techniques. But much of the criticism was not concerned with the correctness or incorrectness of the views I expressed. It was concerned with whether any book should have been written on this subject at all. It is characteristic of our times that many intelligent and sincere people are willing to argue that it is immoral to think and even more immoral to write in detail about having to fight a thermonuclear war.

By and large this criticism was not personal; it simply reflected the fact that we Americans and many people throughout the world are not prepared to face reality, that we transfer our horror of thermonuclear war to reports about the realities of thermonuclear war. In a sense we are acting like those ancient kings who punished messengers who brought them bad news. This did not change the news; it simply slowed up its delivery. On occasion it meant that the kings were ill informed and, lacking truth, made serious errors in judgment and strategy. In our times, thermonuclear war may seem unthinkable, immoral, insane, hideous, or highly unlikely, but it is not impossible. To act intelligently we must learn as much as we can about the risks. We may thereby be able better to avoid nuclear war. We may even be able to avoid the crises that bring us to the brink of war. But despite our efforts we may some day come face to face with a blunt choice between surrender or war. We may even have war thrust upon us without being given any kind of a choice. We must appreciate these possibilities. We cannot wish them away. Nor should we overestimate and assume the worst is inevitable. This leads only to defeatism, inadequate preparations (because they seem useless), and pressures toward either preventive war or undue accommodation.

Many terrible questions are raised when one considers objectively and realistically the problems created by the cold war and the armaments race. 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. My colleagues and I have sought answers to such questions as these: How likely is accidental war? How can one make it less likely? How dangerous is the arms race today? What will it be like in the future? What would conditions be if a nuclear attack leveled fifty of America’s largest cities? Would the survivors envy the dead? How many million American lives would an American president risk by standing firm in differing types of crises? By starting a nuclear war? By continuing a nuclear war with the hope of avoiding surrender? How many lives would he risk? How is it most likely to break down? If it does break down, what will be the consequence? Are we really risking an end to all human life with our current system? If true, are we willing to risk it? Do we then prefer some degree of unilateral disarmament? If we do, will we be relying on the Russians to protect us from the Chinese? Will the world be more or less stable? Should we attempt to disarm unilaterally? If the answers to these last questions depend on the degree of damage that is envisaged, are we willing to argue that it is all right to risk a half billion or a billion people but not three billion?

There seem to be three basic objections to asking these types of questions:

1. No one should attempt to think about these problems in a detailed and rational way. 2. What thinking there is on these problems should be done in secret by the military exclusively, or at least by the government. 3. Even if some of this thinking must be done outside the government, the results of any such thought should not be made available to the public.

It is argued that thinking about the indescribable horror of nuclear war breeds callousness and indifference to the future of civilization in our planners and decision makers. It is true that detailed and dispassionate discussion of such questions is likely to look incredibly hard-hearted. It should also be clear, at least to thoughtful readers, that such questions must be considered. The reality may be so unpleasant that decision makers would prefer not to face it; but to a great extent this reality has been forced on them, or has come uninvited. Thanks to our ever-increasing technology, we are living in a terrible and dangerous world; but, unlike the lady in the cartoon we cannot say, “Stop the world, I want to get off. We cannot get off. Even the most utopian of today’s visionaries will have to concede that the mere existence of modern technology involves a risk to civilization that would have been unthinkable twenty-five years ago. While we are going to make major attempts to change the nature of this reality, accepting great risks if necessary, most of us are unwilling to choose either a pronounced degree of unilateral disarmament or a preventive war designed to “settle” our problems one way or another. We therefore must face the facts that thermonuclear bombs now exist [and that] unless we are willing to abdicate our responsibilities, we are pledged to the maintenance of terrifying weapon systems with known and unknown, calculable and incalculable risks, unless and until better arrangements can be made.

If we are to have an expensive and lethal defense establishment, we must weigh all the risks and benefits. We must at least ask ourselves what are the likely and unlikely results of an inadvertent war, the possibilities of accident, irresponsibility, or unauthorized behavior on the other side as well as on our own.

A variation of the objection to careful consideration of these problems focuses on the personality of the thinker. This argument goes: Better no thought than evil thought; and since only evil and callous people can think about this, better no thought. Alternatively, the thinker’s motives are analyzed: This man studies war; he must like war— much like the suspicion that a surgeon is a repressed sadist. Even if the charge were true, which in general it is not, it is not relevant. Like the repressed sadist who can perform a socially useful function by sublimating his urges into surgery, the man who loves war or violence may be able to successfully sublimate his desires into a careful and valuable study of war. It does indeed take an iron will or an unpleasant degree of detachment to go about this task. Ideally it should be possible for the analyst to have a disciplined empathy. In fact, the mind recoils from simultaneously probing deeply and creatively into these problems and being conscious at all times of the human tragedy involved.

This is not new. We do not continually remind the surgeon while he is operating of the humanity of his patient. We do not flash pictures of his patient’s wife or children in front of him. We want him to be careful, and we want him to be aware of the importance and frailty of the patient; we do not want him to be distracted or fearful. We do not expect illustrations in a book on surgery to be captioned: “A particularly deplorable tumor,” or “Good health is preferable to this kind of cancer.” Excessive comments such as, “And now there’s a lot of blood,” or “This particular cut really hurts,” are out of place although these are important things for a surgeon to know. To mention such things may be important. To dwell on them is morbid, and gets in the way of the information. The same tolerance needs be extended to thought on national security.

Some feel that we should consider these problems but view them with such awe and horror that we should not discuss them in normal, neutral, professional everyday language. I tend to disagree, at least so far as technical discussions and research are concerned. One does not do research in a cathedral. Awe is fine for those who come to worship or admire, but for those who come to analyze, to tamper, to change, to criticize, a factual and dispassionate, and sometimes even colorful, approach is to be preferred. And if the use of everyday language jars, that is all the more reason for using it. Why would one expect a realistic discussion of thermonuclear war not to be disturbing?

The very complexity of the questions raised is another reason why many object to their consideration. There is no doubt that if we reject hard thinking about alternatives in favor of uncritical acceptance of an extreme position we make the argument simpler and most of us prefer simple arguments.

To summarize: Many people believe that the current system must inevitably end in total annihilation. They reject, sometimes very emotionally, any attempts to analyze this notion. Either they are afraid of where the thinking will lead them or they are afraid of thinking at all. They want to make the choice, between a risk and the certainty of disaster, between sanity and insanity, between good and evil; therefore, as moral and sane men they need no longer hesitate. I hold that an intelligent and responsible person cannot pose the problem so simply.

The last objection to detailed thought on thermonuclear war rests on the view that the subject is not only unpleasant but difficult. Many people feel that it is useless to apply rationality and calculation in any area dominated by irrational decision makers. This is almost comparable to feeling that it would be impossible to design a safety system for an insane asylum by rational methods, since, after all, the inmates are irrational. Of course, no governor or superintendent would consider firing the trained engineer, and turning the design over to one of the lunatics. The engineer is expected to take the irrationality of the inmates into account by a rational approach. Rational discussions of war and peace can explicitly include the possibility of irrational behavior.

Of course, analysts may be misled by oversimplified models or misleading assumptions, and their competence readily attacked. However, except for irrelevant references to game theory and computers, such attacks are rare, and are usually so halfhearted that it is clear that their main motivation is not to expose incompetency. Given the difficulty of the problems, one would expect the critics to work more effectively on the obvious methodological problems and other weaknesses of present-day analysts.

Critics frequently refer to the icy rationality of the 91 Institute, the Rand Corporation, and other such organizations. I’m always tempted to ask in reply, “Would you prefer a warm, human error? Do you feel better with a nice emotional mistake?” We cannot expect good discussion of security problems if we are going to label every attempt at detachment as callous, every attempt at objectivity as immoral. Such attitudes not only block discussion of the immediate issues, they lead to a disunity and fragmentation of the intellectual community that can be disastrous to the democratic dialogue between specialist and layman. The former tends to withdraw to secret and private discussions; the latter becomes more and more innocent, or naive, and more likely to be outraged if he is ever exposed to a professional discussion.

Finally, there is the objection that thermonuclear war should not, at least in detail, be discussed publicly. Even some who admit the usefulness of asking unpleasant questions have advocated raising them only in secret. One objector pointed out to me that if a parent in a burning building is faced with the problem of having to save one of two children, but not both, he will make a decision on the spur of the moment; it wouldn’t have made any difference if the parent had agonized over the problem ahead of time, and it would have been particularly bad to agonize in the presence of the children. This may be true, but other considerations dominate our nation’s choices; our capabilities for action and the risks we are assuming for ourselves and thrusting on others will be strongly influenced by our preparations both intellectual and physical. Other reasons for this objection to public discussion range all the way from concern about telling the Soviets too much, and a fear of weakening the resolve of our own people, through a feeling that public discussion of death and destruction is distastefully comparable to a drugstore display of the tools, methods, and products of the mortician. Perhaps some or all of these objections to public discussion are well taken. I do not know for sure, but I think they are wrong.

They are wrong if we expect our people to participate rationally in the decision-making process in matters that are vital to their existence as individuals and as a nation. As one author has put it: “In a democracy, when experts disagree, laymen must resolve the disagreement.” One issue is whether it is better that the lay public, which will directly or indirectly decide policy, be more or less informed. A second issue is whether the discussion itself may not be significantly improved by eliciting ideas from people outside of official policy-making channels.

There are in any case at least two significant obstacles to full public debate of national security matters. The first, of course, is the constantly increasing problem of communication between the technologist and the layman, because of the specialization (one might almost say fragmentation) of knowledge. The other lies in the serious and paramount need to maintain security. Technical details of weapons’ capabilities and weaknesses must remain classified to some degree. Nonetheless, technical details may be of vital importance in resolving much broader problems. (For instance, who can presume to say whether the military advantages of atomic weapons testing outweigh the obvious political and physical disadvantages unless he knows what the military advantages are.) Moreover, those who feel that in some areas “security” has been unnecessarily extended must concede that in certain areas it has its place. To that extent the functioning of the democratic processes must be compromised with the requirements of the cold war and modem technology. Fortunately, non-classified sources often give reasonable approximations to the classified data. I would say that many of the agonizing problems facing us today can be debated and understood just about as easily without classified material as with provided one carefully considers the facts that are available.

It is quite clear that technical details are not the only important operative facts. Human and moral factors must always be considered. They must never be missing from policies and from public discussion. But emotionalism and sentimentality, as opposed to morality and concern, only confuse debates. Nor can experts be expected to repeat, “If, heaven forbid. ….,” before every sentence. Responsible decision makers and researchers cannot afford the luxury of denying the existence of agonizing questions. The public, whose lives and freedom are at stake, expects them to face such questions squarely and, where necessary, the expert should expect little less of the public.
