JOSHUA LEDERBERG A FREEZE ON MISSILE TESTING “From a technical standpoint, the most amenable place for controls is testing; a comprehensive freeze on all missile tests would be most easily verified and would provide the utmost assurance against the perpetuation of a costly technology race.” Joshua Lederberg is executive head, department of genetics, Stan- ford University Medical School. He received the Nobel Prize in Medicine and Physiology in 1958 with George W. Beadle and E, L. Tatum. An abridged version of this article appeared in the “Washington Post.” The strategic arms limitations talks (SALT), which will resume in Vienna this spring, have been la- beled as the key to world survival through the next decade. Even if we frame the arms race as a by-product of international politics rather than as a living, demoniacal being with independent existence, no one doubts the value of a critical search for practical limitations on the arms spiral. Arms investment is shaped by dy- namic interplay of domestic and in- ternational forces, actions and reac- tions, as much as by negotiated agree- ments. More than any other process, nevertheless, these explicit agree- ments require us to examine the as- sumptions that underlie our strategies of defense and of conciliation. In my own view the most import- ant function of the arms limitation conferences is their educational value for the participants so that the many internal policy-making forces within each country may better understand the full depth of their national in- terests, and how these may be pur- sued in the light of the perceptions of the other nations. It would then be a mistake, as Fred Ikle stressed for other reasons in “How Nations Negotiate,” to judge the value of diplomatic negotiations solely in terms of the agreements formally concluded. Complicated multi-national inter- ests, or more often the confusion of 4 sternal debate, may demand the evidence of a formal treaty to affirm a mutually rewarding accommoda- tion. But, at times, the negotiators should be congratulated for refusing a pretense of agreement when such an understanding was beyond the comprehension, the ingenuity, the interests or the power of the parties. The sentimental idea that agree- ments should be not only discussed but accepted in a spirit of willing- ness to compromise national inter- ests will make it more difficult to get countries into active negotiation and exploration of the congruence of their true interests. It leads to such absurdities as refusing to dis- cuss arms control with the USSR after combative actions in Czecho- slovakia or the Middle East, as if we would otherwise be granting them a favor contrary to our own interests as part of an arms control package. A compromise of conflicting na- tional interest may well be a rational goal of negotiation. This is based on the assumption that both parties can find a benefit from a non-zero- sum game, and has nothing to do with amicable sentiment or mutual approbation. General disarmament, whether unilateral or by treaty, is emphatical- ly not in question. Nothing would throw the world in greater turmoil than to leave its resources to appro- priation or hijacking by any pirate with a left-over hand grenade or machine gun. Nor are we politically, socially or economically ready for the peaceful coalescence of sovereign- ties into the unified world govern- ment that must precede the disap- pearance of national military forces. .To paraphrase the still cogent ar- guments of the naval strategist A. T. Mahan, the peaceful borders between the United States, Canada and Mexi- co are quiet just because there is no ambiguity about the distribution of military power. Had we solved the problems of cultural accommodation, as well as economic and political ad- justment, among the people of the continent, we could also consider the actual merging of sovereignty and of military power. This is an ideal we must pursue with more realism than piety; but the harsh news of the day points the other way — we may still fail to halt the division of the nations into blacks and whites, Chicanos or French and English. Even a threat of common doom may be insufficient to enforce the dissolu- tion of national sovereignties against the resistance of economic disparities like those between India and the West. Both sides know that every chance of industrial modernization would evaporate if the world’s cap- ital were equally diffused and con- sumed in a population explosion. The ‘‘white man’s burden” in con- temporary terms is to find some way that does work for the effective shar- ing of capital for the development of the poor countries; if not, we will be relieved of that burden willy-nilly. Economic Factors In the eyes of the poor countries, our commitment to the arms race has drained the very resources that might finance international development. Their political pressure (like an im- plicit threat that India might join the nuclear club) is certainly among the main forces that have dragged the United States and the USSR to the conference tables in Vienna, Helsinki and Geneva. Were rational calculation at the helm in the policy- making foci of both superpowers, this would have been unnecessary. Whether the pattern of arms lim- itation now under negotiation with- in the SALT framework will result in much savings from arms budgets is problematical. This benefit may be a long-range consequence of the political stability that is the central aim of strategic policy. In the short run, there is more likely to be only a shifting of expenditures to the pro- grams left out of the agreements. The obvious and in many ways de- sirable contender here is the naval option. Despite its expense as a launch platform, the submarine has long been advocated as the way to separate the retaliatory force from vulnerable cities, and to provide an- other resource for assured destruc- tion of an attacker. Qa igmicctauncis _ eeS Sittace Mhips.wtespite their vuln- erability, may also be undeservedly neglected as féXpensive-deceys andy, ERE sektomepeteresyet o to dilute an enemy's first strike ‘cap capability. The mix of cheap, vulnerable platforms must, however, be carefully cali- brated if it is not to be confused with a force useful only for a first strike. There will be no lack of alternative proposals —- some quite plausible — to buy more reliability and to plug potential gaps in systems dedicated to infinite security. Overkill Potential Another stated argument for arms control is that the very accumulation of the stockpile, with its vast poten- tial for overkill, makes it more likely that nuclear war will break out. There is a core of rationality to this argument. The technology of nu- clear weapons is likely to leak and proliferate in some proportion to the total effort devoted to them. The nonproliferation treaty would have been unnecessary if every nonnuclear country had first had to finance a Manhattan project to learn to make a bomb. Furthermore, the chance of an unauthorized psychotic or acci- dental firing with its potentially cata- strophic consequences is larger the more weapons abound, other things being equal. The superpowers, how- ever, are technically and politically constrained to invest more effort in protective systems for their large stockpiles, and countries like France and China which are still develop- ing their nuclear capabilities prob- ably present more serious threats of significant accident. As to “overkill,” the metaphor makes sense for a first-strike capa- bility — a small percentage of the stockpile of either superpower could wipe out civilization — but a cred- ible deterrent must still be perceived as inflicting intolerable injury after having absorbed a preemptive attack. Overkill potential is exactly what stabilizes the system to make the act- ual use of a nuclear weapon in anger unlikely. From this point of view, it is point- less to discuss nuclear parity or suf- ficiency or superiority in terms of numbers of missiles, which is the fashionable game of the decade. The accuracy of intelligence about the location of missile launch sites, the precision of guidance, the shrewdness of target selection, the security of command and control and, above all, how well these are perceived by an enemy and by ourselves — these now become far more crucial to deterren- cy than an advertisement of crude numbers of missiles or of warheads. The essential function of strategic arms is to ensure that they will never be used by either side, and that any threat of their use works to stabilize rather than to inflame the relations of competing nations. The arms race having progressed to an effective stalemate, which has worked better than anyone could have hoped 25 years ago, its main hazards today come from its side ef- fects on both international and na- tional policies. The most serious of these is an unremitting anxiety and suspicion about possible technical breakthroughs that might topple the stalemate. At one level, this leads to the mutual reinforcement of dis- trust about each side’s intentions and plans. At another it provokes the constant search for the technology to do it first here. The main argument openly leveled by most academic physicists against the ABM is that it simply will not do any of the several jobs for which it is purportedly designed. The real force of their anxiety is that a long- range program of ABM_ research might eventually develop methods that more credibly offer a prospect of antimissile defense. Needless to say, it would be com- forting to imagine a world in which the defense had a real margin over attack. But how do we get there, except through closely monitored mutual agreements? In the process, the existing balance will be broken, and we will face the most serious risks of either side’s feeling com- pelled to undertake a preemptive at- tack. At the very least both sides would strive to redouble their of- fensive weaponry in order to sustain the credibility of their retaliatory potential. Effective defense against missiles evidently remains quite remote, but it might be technically achieved at the far end of an extensive program of trial and development, of which Safeguard is the first step. This is a technological ‘Race to Oblivion,” the history of which has been author- itatively documented in Herbert York’s recent book of that title. Need For Creativity Dr. York recounts how the arms race mentality was exploited with great skill and mendacity in the 1960s to fund redundant and use- less weapons systems, and to ensure that each of the services in an im- perfectly unified defense establish- ment would be placated. He believes, as I do, that the security of the coun- try depends only in part on technical innovation, and that we must address our greater efforts to stabilizing the security of the world if we are to have any for ourselves. But we can- not overlook the need for techno- logical creativity which will rapidly disappear if we do not repair the sources of the cynicism of our youth about the legitimacy of our national! goals. By building so heavily on technological bases of security, while neglecting the causes of internal dis- affection, we have impaired our mil- itary security far more than any mis- sile deficit would imply. Dr. York also recounts the over- reactions initiated by the United States to the Soviet development of March 1971 Bulletin of the Atomic Scientists 5 Sputnik and of their early ICBMs. Perhaps naively, he attributes the Soviet deployment beginning in 1967 of the SS-9 missiles, with their im- mense 25 megaton warheads, to re- dressing the boasts of U.S. defense officials about our nuclear superior- ity. These were made “in order to be able to resist internal pressures for still greater expansion of our of- fensive forces.” Such boasts and gen- erally the two-sided demand for clear Superiority over the other in missile counts will add up to little advantage for either. Perhaps they are a psy- chological necessity for people who sense the threat of mutual annihila- tion. But they are an irrational re- sponse that can do little but worsen the odds. The Cuban Crisis Mutual misperceptions of strategic posture undoubtedly fueled the grav- est confrontation to date, the Cuban missile crisis in 1962. Dr. York re- calls how we grossly overrated the military significance of Sputnik in 1957. The Soviets had, in fact, over- built their rockets in a way that suited them for space flight but slowed up their deployment in stra- tegically significant numbers. The missile gap myth of the 1960 election campaign was based on vastly in- flated estimates of the Soviet opera- tional capability. This is a difficulty inherent in any intelligence organi- zation, which will never be criticized as much for drawing the most ex- tensive implications out of fragmen- tary data, as it would be for over- looking any possibility. Arthur M. Schlesinger, Jr., in his memoirs “A Thousand Days” makes the curious remark that the Soviets in 1960 were “innocent of the higher calculus of deterrence as recently de- veloped in the U.S.” Therefore, they could not comprehend the sta- bilizing purpose of President Ken- nedy’s plans to enhance U.S. missile- ry. Knowing the actual strength of their own forces they may in fact have viewed Kennedy's missile pro- gram in the same way that Secretary Laird construes the SS-9s, namely the development of a first strike poten- tial that could smother the ability to retaliate. “Too bad, that’s their problem!,” 6 some might say. But that confusion may explain Khrushchev's Cuban gambit, a desperate move that would have been senseless as a direct stra- tegic threat against the United States — provided the Soviet really had an ample long-range missile force based on their own soil. When your opponent has nuclear weapons, his jitters are your problem too. (The interpretation of the 1962 Cuban missile crisis is borne out by Roger Hilsman’s account of its back- ground in “To Move a Nation.’’) The Cuban gambit had to be re- _ sisted for its potential side-effects on Latin-American politics, more than as an element in strategic deterrency. It does suggest one avenue that might be opened up for a negotiated pro- gram of low-cost mutual security. In 1961, the late Leo Szilard wrote a fictional parable, “The Mined Ci- ties” (Bulletin, December 1961), wherein the superpowers had ex- changed the capability of assured destruction by allowing the major cities to be mined by the other side. The idea has been revived from time to time — but like Rep. Craig Hos- mer’s suggestion that we multiply world security by giving every coun- try four A-bombs — it does an in- genious metaphor the worst injustice to take it too literally. The parable does point out that our cities are hostages to one another, whether the bombs are underground, or need to be delivered by a 30-minute rocket flight. (This reasoning also makes one question whether Moscow and Washington are the right cities to be shielded with ABM, when the po- tentates would make the most cred- ible hostages.) Why not then agree that the problem of mutual security has some technical solution, achiev- able at the lowest mutual cost. The establishment of a Soviet mis- sile base in Cuba, or American bomb- ers in Libya entailed political com- plications almost as unacceptable as giving extraterritorial access into the U.S. capitol to a Soviet bomb squad. And where would we fit the French and the Chinese? The nondeployment of a potential ABM system is a constructive equiv- alent to cheapening the hostage sys- tem, with the fewest side effects. MIRVs (multiple independently tar- geted reentry vehicles) complicate the deterrence equations, giving the first-striker a better chance to destroy a deterrent, but the naval option and a multiplication of feints are as plaus- ible answers as any forseeable ABM. As far as arms control is concerned, once the potential for MIRV was understood little room was left for any verifiable control over its further development. Indeed, the need to play out this act so that both sides could work out the implications of MIRV may have compelled the post- ponement of SALT until now. If we separate the gimmickery from the parable behind “The Mined Cities,” we can see that the naval options may give us the greatest room for. mutual advantage. Ironical schemes can be composed that point up some of the absurdities of the world system. For example, it would be more to our advantage if Soviet submarines refueled at Portland, Maine, than at Cienfuegos, Cuba; and we might offer to exchange base privileges on U.S. shores for their equivalent on the Black and Baltic Seas. But even if such superrational exchanges could be negotiated, they would raise untold mischief through disputes over the interpretation of the guaranteed free access on which they would have to be based. Better that we work out a de facto equili- brium, provided that this is based on the clear understanding that any solu- tion must provide for a zone of stra- tegic security on both sides,. or noth- ing but desperate maneuvering can follow. Surprise Attack The greatest anxiety about surprise attack in the next decade — for both sides are in fact expanding the naval option — is that new technology may impair the invulnerability of the submarine. It is absolutely in- conceivable that antisubmarine de- tection and warfare could reach the point of reliably removing the bulk of a retaliatory force in a single sur- prise attack, without having first been widely exercised and tested. Mutually advantageous agreements to limit such testing should be fairly amenable to verification. They could (Continued on page 43) TESTING FREEZE (Continued from page 6) a oe ——— be a logical extension of the existing ban on testing nuclear weapons un- der water. There is also a danger that units of naval strategic force may become involved in tactical conflicts, with a consequent erosion of the line that marks nuclear weapons off from all others. This will require very careful attention to our own doctrine. The problem of surprise attack can be formulated in more precise, quant- itative terms than any other aspect of defense strategy. There are still many uncertainties, for example the operational reliability of immense computer programs, and the level of nuclear retaliation that would be so _ “unacceptable” to a potential attack- er as to deter him. Nevertheless, the analyst can make a fairly simple model of the array of forces, and ig- nore the complexities of mass psy- chology and serpentine recalculation that blur the scientific predictability of any political confrontation. The simplicity of the problem to the ra- tional analyst, and its appeal to the paranoia of the antirational, have captured our attention and resources out of proportion to the role of sur- prise attack in world conflict. By over-designing our solutions to that problem, we leave ourselves ever less prepared to cope with the actual dif- ficulties of today’s world. The nuclear deterrent can play no direct role in dealing with the Soviet penetration of Africa, harassment by air pirates or the reenslavement of Czechoslovakia. These have no easy answers, but they clearly require the rebuilding of a sense of community March 1971 with our allies and friends, who are inevitably isolated by a historic trend of unilateral force commitments and defense investments typified by Vietnam and by the ABM. Freeze Proposed All sides are approaching the con- clusion that mutual defense against surprise attack needlessly consumes an inordinate portion of world te- sources. We seek a new pattern of reciprocal arms disposal whose very momentum would be the best assur- ance that it was not merely a gambit for strategic advantage. This would be hard to construct, merely against the fears, angers and entrenched in- terests of important elements within both superpowers. A simple moratorium on the em- placement of strategic weapons has been suggested, but it is likely to be entangled in contentious differences over whether it should embrace air- craft, tactical missiles and so on. From a technical standpoint, the most amenable place for controls is testing; a comprehensive freeze on all missile tests would be most easily verified and would provide the ut- most assurance against the perpetua- tion of a costly technology race. It would complicate some peaceful ap- plications of space technology. How- ever, none of these requite precise reentry after a brief, high velocity flight. Furthermore, nothing would be lost in requiring a definite pat- tern of international participation in Space missions to assure that these were a net benefit to the whole earth from which they have embarked.
