"Nuclear war cannot be won, and must never be fought." -- President Ronald Reagan

1. President Reagan's brief sentence sums up the fundamental operating principle of U.S. and Soviet political leaders of the past two decades concerning nuclear weapons. Since at least the Cuban Missile Crisis of October 1962 the actions of both superpowers have been constrained by the knowledge of both countries that nuclear weapons have no military value. The use of them in war is the supremely irrational act.

2. At the same time, the political leadership of both countries has either actively sought or grudgingly approved the growth of nuclear arsenals and the development of new nuclear weapons systems. Why, if there is no military purpose for them? It is clear that nuclear weapons must have great political value in the eyes of political leaders. The danger confronting the world in the late twentieth century is that these political pressures to build nuclear arsenals will create a situation where the fundamental truth as expressed by President Reagan will be ignored, overpowered, or simply forgotten, and that nuclear war will occur.

I. NUCLEAR WEAPONS HAVE POLITICAL, NOT MILITARY, USES

3. In order to prevent nuclear war, a variety of strategies and tactics needs to be pursued. Trouble spots around the world which could flare into U.S./Soviet confrontation need to be isolated from that confrontation and resolved diplomatically. The spread of nuclear weapons needs to be checked. The nuclear relationship between the U.S. and the Soviet Union needs to be managed and directed through arms control agreements. And the political pressures for building nuclear weapons need to be examined and lessened if possible. This paper is about the latter task and how it relates to the others.

4. The political uses of nuclear weapons fall into two arenas: international and domestic. The greatest of these is in the international arena; one. country's nuclear weapons seem to dissuade other countries from using their own nuclear weapons. This political process is known as deterrence. It is a political condition which has existed now for more than thirty years, and obtained when nuclear powers had relatively small arsenals, as well as when those countries have far larger stocks of weapons, as is currently the case. It is also a condition fraught with ambiguities and pitfalls -- both political and moral. It is the fundamental rationale for the expansion of nuclear arsenals, and it is inescapably founded on the willingness to do the unethical and irrational.

. . . our nation's present commitment to the doctrine of deterrence assumes the production and deployment of nuclear weapons, and the threat to use them is implicit in the deterrence theory. Our ethical dilemma is that weapons whose use cannot be justified are needed to sustain the balance of fear in which nuclear warfare has been prevented for more than three decades. That ethical dilemma will remain until the nations can agree to eliminate nuclear weapons from the earth. ("Mandate for Peacemaking," adopted by the 11th general convention of The American Lutheran Church, September 1982, section A-b).

5. Within the deterrence doctrine lay the seeds for its own failure. In order for a country credibly to deter another country's use of nuclear weapons, it must convey the perception that it is willing to do the irrational -- use its nuclear arsenal in war. In order to do that, it must make the irrational appear rational (or as rational as possible). In order to do that, both the U.S. and the Soviet Union have attempted to create nuclear weapons which appear to the other to have a rational military use. This has led both countries to build weapons progressively smaller and more accurate. At some point the weapons of one or both of the countries will become apparently rational in military terms to their own leadership. At that point deterrence fails, and nuclear war moves from a possibility through miscalculation to a probability through the calculus of the apparently rational.

6. And while deterrence -- especially deterrence at low levels of armaments and within the context of arms control and other methods of managing this political relationship -- may serve a fundamentally good political purpose, nuclear weapons have other political effects and uses in the international arena. First, they have been brandished trying to influence the actions of other countries in regional disputes (during the 1973 war in the Middle East, for example). Second, because of the need to preserve the credibility of deterrence, resolution of political problems between the U.S. and the Soviet Union may be prevented. The effects of deterrence are to entrench differences between two countries, such as the continuing division of Europe, rather than allow them to be resolved through political and diplomatic means.

7. Thus, the political uses of nuclear weapons in international relations are mixed. The domestic political uses of nuclear weapons supplement the dangers inherent in international uses, and thus are more malign. John Kennedy, for example, raised the issue of nuclear weapons for at-home political purposes during the 1960 presidential campaign, when he spoke of a "missile gap" and blamed it on the Eisenhower-Nixon Administration. As a result of such domestic campaign rhetoric, new and more apparently usable nuclear weapons are built, even though deterrence has shown no signs of failing. The new weapons then contribute to the destabilization of the deterrence relationship, which leads to calls for still more weapons on both sides, and the cycle perpetuates itself.

8. Christians in the United States who seek to prevent nuclear war, then, are called upon to examine carefully the rationales used in defense of additions to nuclear arsenals. Because of its inherent dangers, and conflicts with the traditional ethical standards of the Christian community, deterrence can only be tolerated at the lowest possible levels of armament, and only within the context of other nuclear-war-preventing activities like arms control and efforts to halt the proliferation of nuclear weapons.

II. BURDEN OF PROOF ON PROPONENTS OF MORE

9. What assumptions must be made, and what criteria are necessary, to help Christians evaluate the necessity of additional nuclear weapons? In a democracy, how do we judge whether our government should or should not build a nuclear weapon system?

10. There are two levels of evaluations that can be made. The first stands without reference to other criteria and ethical standards. It stems simply from the current situation in the world. Henceforth, the relevant question about a nuclear weapons system cannot be "why not build it?" but ought be "why build it?"

11. The burden of the argument therefore must fall on the proponents of the weapon system, rather than on the opponents. A presumption against additional weapons is the prudent stance. This is especially important given recent research into the effects of even a relatively "limited" nuclear exchange on the global environment. The presumption must be that nuclear weapon systems require especially compelling justification.


possession of nuclear weapons can only be justified by their political usefulness . . .
the only political use acceptable to the just-war tradition is prevention of nuclear war


12. In national debate over nuclear weapons, no longer must opponents of a weapon be required to demonstrate that the weapon violates a set of ethical and/or political criteria. Rather, supporters of a weapon should demonstrate that it falls within such a set of criteria, and fully describe what that set of criteria is.

13. This is a significant change in thinking about nuclear weapons in the United States; it addresses the domestic political use of nuclear weapons at its core. Up to now, it has been the opponents of strategic and tactical nuclear weapons That have had to make their case in Congress, and in cities and towns across the country. That may or may not have been the appropriate basis of debate in the past. That is not the importance of this point. What this fact demonstrates is that up to now, political leadership has found it politically safer, in general, to support nuclear arms with some exceptions than, in general, to oppose nuclear arms with some exceptions. It is this political dynamic which should be reversed.

14. After this initial presumption, the next level of evaluation is a general evaluation stemming from a set of ethical standards to determine which weapons, if any, may be exceptions to the initial presumption against any new weapons.

15. The Lutheran tradition, along with the vast majority of Christians through history, has accepted the just-war tradition as the set of ethical standards to be used in this realm. Within the church a tradition of pacifism has coexisted with the more widely held just-war ethic. Most adherents to the pacifist tradition would end their ethical evaluations of weapons at this point -- not because they are lazy or simplistic, but because of the rigor of their ethical standards. Those Christians who do not adhere to pacifism need to be equally rigorous in their ethical process.

The just/unjust war ethic does not excuse believers from the rigor of ethical thinking and decision-making on war and peace. Just-war thinking rules out the option of unthinking compliance with whatever policies a nation's political and military leadership happens to be offering the people at a given time. ("Mandate for Peacemaking," A-9).

16. The just-war tradition clearly prohibits the firing of nuclear weapons, or other weapons of mass destruction, because doing so would violate the conditions of proportionality and of protection of non-combatants from attack. The dilemma presented to "just warriors" by deterrence is the distinction between use and possession of weapons of mass destruction. The possession of such weapons can only be justified by their political usefulness, and the only political use which withstands scrutiny from the perspective of the just-war tradition is the prevention of nuclear war ) through deterrence, through arms control, and through nuclear non-proliferation. (For a discussion of this, see the appropriate chapters of Peaceways, Charles P. Lutz and Jerry L. Folk, et at., and When War Is Unjust, by John Howard Yoder, both from Augsburg Publishing.)

17. The reason for this is that other political uses, especially in the domestic political arena, augment the apparent military usefulness of nuclear weapons, as already discussed. These political uses, and how they can be prevented, or at least ameliorated, are the issues the just-war adherent must tackle in evaluating nuclear weapons.

III. SEVEN QUESTIONS WE CAN ASK

18. Nuclear weapons are used for a variety of political purposes. The questions non-pacifist Christians must ask about a nuclear weapon should be designed to determine whether that weapon will help prevent nuclear war (the only acceptable use) or is being proposed for some other political reason. We hope the following questions do just that.

A. Will the system actually accomplish its stated objective? And is the objective stated correctly?
19.
Many Lutherans, especially those in the Midwest, remember a series of Nike missile bases designed to use nuclear-tipped missiles to shoot down Soviet bombers attacking the U.S. The system was built in the late 50s, and was essentially scrapped in the late 60s and early 70s. There was a debate about whether to continue it or not. The situation was this: in the 50s, most of the Soviet nuclear weapons would have been dropped on the U.S. by bombers. By the late 60s, by far most of the Soviet warheads would have been "delivered" to the U.S. on rockets. The Nike system could still shoot down the bombers, but what good would that do if Soviet rockets still destroyed the U.S.?

20. It was relatively easy to come to the conclusion that it didn't make sense to keep the bases. They weren't going to help deter a nuclear war by convincing the Soviet Union that it was useless to attack the U.S. That was the key to the debate on the matter. The missiles could still shoot the Soviet bombers, but that objective didn't make a difference any longer. The primary objective is to prevent nuclear war. The missile's objective could no longer help accomplish that. Yet many still asked why dismantle a perfectly good weapon system? It's never been politically easy to get rid of nuclear weapons even if they've outlived their usefulness.

B. Are there other safer, less costly, or non-nuclear, means of accomplishing the objective?
21.
In the 60s, the U.S. built the Titan missile system to deliver nuclear warheads. The U.S. is now in the process of dismantling them, because they are old, expensive to maintain, and dangerous (it was a Titan missile that exploded in its silo some years ago and hurled its warhead onto a farmer's field). There were only 54 Titan missiles with 54 warheads in the U.S. arsenal, and in light of the 1000 Minuteman missiles with several thousand warheads, the Titans weren't necessary to deter nuclear war. Nonetheless, there was opposition to retiring the missiles, because it was claimed that it was an act of "unilateral disarmament." The missile's objective, for those who opposed its retirement, had become something other than the prevention of nuclear war.

22. Another case is the issue of nuclear weapons on sea-launched cruise missiles (SLCMs). These missiles are small, highly accurate, jet-powered missiles. The Navy is now putting them on ships, to be used to attack other ships on the high seas. We should question whether they need nuclear warheads, or whether conventional explosives would just as effectively serve the objective. This use of nuclear warheads falsely increases their apparent military purpose, weakens deterrence, and does not make the weapon more capable of accomplishing its objective (sinking ships -- remember the British destroyer Sheffield sunk by an Argentine Excocet missile with conventional explosives) than conventional weapons would. It also highlights another political use of nuclear weapons: to "look tough." Many politicians think they gain the most political support by advocating weapons more powerful than necessary.


when nuclear weapons are used to send diplomatic signals, attract votes, provide jobs,
or win political squabbles... it becomes harder to prevent nuclear war


C. Can the objective even be accomplished?
23.
This is, of course, one of the unanswered questions concerning the Strategic Defense Initiative. But it is one which has not been asked seriously enough in the development of other nuclear or strategic weapons systems, either. A classic example was the so-called "atomic cannon" built by the U.S. in the 50s. It was to be stationed in Europe, to defend against a Soviet attack. When they were sent to Germany, it was discovered they were too big to drive through the narrow streets of the towns and villages, and because they were built with wheels, rather than tracks (like a tank), they couldn't go across country. They simply could not do what they were designed to do.

24. Another example is the Pershing II rockets and ground-launched cruise missiles (GLCMs) the U.S. is now deploying in Europe. In response to the Soviet deployment of SS-20 missiles, NATO leadership thought it was necessary to deploy new weapons. A variety of weapons could have accomplished that objective, based on ships in the Atlantic ocean or on planes based on ships or in countries that already had nuclear weapons. The European political leaders, however, requested Pershing us and GLCMs in order to assure Europeans of U.S. loyalty to them by having weapons deployed on the ground in Germany, Holland, Belgium, and Italy. The objective was to express political solidarity within the NATO alliance. The deployment, however, is still causing political difficulties within the very countries it was designed to reassure. Nuclear weapons are for deterring the use of other nuclear weapons, not for sending political signals within an alliance of friendly countries.

D. Does the weapon system promote, inhibit, or have a neutral effect on arms control?
25.
Arms control is another important tool to prevent nuclear war. It does not make sense to deploy weapons which make arms control more difficult. The deployment of some nuclear weapons in submarines is an example of this. The Soviet submarine which was grounded in Swedish waters some years ago was carrying nuclear weapons, but it was not the kind of submarine from which the Soviets could launch rockets, so the weapons must have been either torpedoes or cruise missiles similar in shape and size to torpedoes. Without having an American watching the Soviets load the submarine, however, it is impossible to tell which. If it is impossible to tell what kind of weapon, or the number of weapons, it is impossible to control them through a treaty.

26. The Soviet submarine was not carrying the kind of weapons controlled by treaties already negotiated by the U.S. and the U.S.S.R. (if it had been, it would have been in gross violation of the treaty, and that violation would certainly have been made public). In response to these Soviet weapons, the U.S. is now deploying SLCMs in submarines which haven't previously been included in arms control negotiations. The U.S. SLCMs are like missiles covered under SALT I and SALT II when launched from aircraft. It is equally impossible for the Soviets to know how many of these missiles are deployed, or in what submarines. Thus, the Soviets can't be sure of verifying them. This is also an unnecessary inhibition on arms control. Are nuclear weapons being used for political tit-for-tat?

E. Is arms control being used as the reason to build the weapon?
27.
We cannot afford to ignore history: no weapon system declared to be a bargaining chip in an arms control negotiation has ever been bargained away by our government. (We have less insight into Soviet bargaining tactics, so it is more difficult to make such a statement about the Soviet government, but it almost certainly applies to them, too.) In addition, the politics of arms control in the United States has had an extremely dangerous characteristic: in order to gain approval for an arms control treaty, commitments to build additional weapons not covered by the treaty have been made.

28. Critical evaluation of weapon systems, and the resulting opposition to some of them, has doubtless demonstrated to U.S. political leaders the commitment of the American people to the arms control process. Many would argue (including some current U.S. officials) that without that opposition, the current negotiations would not be under way. Moreover, domestic opposition to specific weapon systems can help to make sure that the domestic politics of arms control serves to slow the arms race, rather than legitimize or even fuel it.

F. Is there a reason to believe the weapon system is being procured for domestic political, rather than national security reasons?
29.
This gets at one of the classic ways weapons make their way through Congress. By spreading the development and production of a weapon around the country, proponents of weapons generate votes in support of those weapons. This is simply the use of nuclear weapons for the political purpose of generating jobs and economic benefits rather than preventing nuclear war.

30. Another, similar dynamic has to do with rivalries among the military services. Nuclear weapons are the most prestigious and politically powerful kinds of weapons for a service to have. But not all forms of nuclear weapons need be given to all services. Yet the U.S. is now building cruise missiles for the Army, Navy, and Air Force. Both the Air Force and the Army have nuclear equipped rockets based on land, and the Navy has rockets based in submarines. Both the Air Force and the Navy have airplanes capable of delivering nuclear weapons. In some cases there is good reason for this; in others, the political realities meant that if one service was to get a nuclear weapon system, the other services had to get one as well, whether it served the purpose of preventing nuclear war or not.

G. In a crisis, does the weapon promote predictability on the part of the antagonists?
31.
The least likely way nuclear war would start is the completely unexpected "bolt-from-the-blue." It is much more possible that one country's misjudgment of the other country's intentions will lead to the use of nuclear weapons in desperation. An important way of decreasing this possibility is to see whether one country's weapons could give another the wrong perception.

32. There are two good recent examples of this. The first is the Soviet Union's mid-70s buildup of large, accurate missiles with many warheads. Whether the Soviets intended to or not, they forced many in the U.S. to the conclusion that the Soviets intended to attack the U.S. missiles. This was the "window of vulnerability" some thought the U.S. faced. The United States, in a crisis, might be faced with the decision either to launch its missiles first, or to see them destroyed if the Soviets struck first. Soviet political leadership had never indicated that such a first-strike on their part was their intention, and many characterized it as an unlikely "cosmic roll of the dice." Nonetheless, because of the perceived capability of the Soviet missiles, U.S. leadership would have to take such a possibility into account.

33. Similarly, the U.S. deployment of Pershing II missiles in Europe has served to make Soviet leaders unsure of U.S. intent. These missiles would take between six and ten minutes to reach the Soviet Union. Soviet leaders are worried that, in a crisis, the U.S. might attempt a surprise attack; the targets would be the offices, headquarters, and shelters of the Soviet political leadership. The Soviet concern has been reenforced by public writings by some U.S. nuclear theorists advocating such a "decapitation" attack as a workable military use of nuclear weapons.

34. Both of these are examples of the kinds of weapons which do not increase security by preventing nuclear war, but rather weapons which decrease security by making judgments in a crisis more difficult. When the Pershing II deployment is criticized using this argument, its supporters counter that it is good that there is some uncertainty in the Soviet Union, because it makes the problem of defending the Soviet Union more difficult. But in any crisis, an accurate assessment of the antagonist's intentions is essential if nuclear war is to be avoided. The purpose of nuclear weapons is to prevent nuclear war, not make problems for the adversary that also make a crisis harder to manage.

IV. CONCLUSION

35. There are nuclear weapons being proposed which may fulfill the requirements of this list of questions. There are many more which will not. So far, other means of helping prevent nuclear war have not been as successful as hoped. Arms control efforts have a mixed record. And the spread of nuclear weapons is a continuing danger to which we have not paid enough attention. That doesn't mean they are failures; it only means that after 40 years, the world is still learning how to prevent nuclear war. But we also have 40 years of experience to learn from.

36. This list of questions is derived from that experience. It alone cannot save us from nuclear war. Only wise leadership in the countries which have nuclear weapons can do that. So far, leadership in both the U.S. and the Soviet Union has kept the first principle of nuclear weapons -- that nuclear war cannot be won and must not be fought. The role of citizens in a democracy is to help those leaders continue to keep it. That is the purpose of this list. As shown in these examples, both the' U.S. and the Soviet Union have at times made that more difficult, not less, in the past decades. There are political uses of nuclear weapons. They can be used to send diplomatic signals, attract votes, prove resolve, provide jobs, or win political squabbles. Almost inevitably, when used for those purposes, it becomes harder, not easier, for leaders to prevent nuclear war.
