But it is hard to make it believed. It would be hard to keep the Soviets from expecting that we would think it over once more and find a way to give them what my children call "one more chance. " Just saying so won't do it. Mossadegh or the anarchist might succeed, but not the American government. What we have to do is to get ourselves into a position where we cannot fail to react as we said we would- where we just cannot help it- or where we would be obliged by some overwhelming cost of not reacting in the manner we had declared.
Coupling Capabilities to Objectives: Relinquishing the Initiative
Often we must maneuver into a position where we no longer have much choice left. This is the old business of burning bridges. If you are faced with an enemy who thinks you would turn and run if he kept advancing, and if the bridge is there to run across, he may keep advancing. He may advance to the point where, if you do not run, a clash is automatic. Calculating what is in your long-run interest, you may turn and cross the bridge. At least, he may expect you to. But if you burn the bridge so that you cannot retreat, and in sheer desperation there is nothing you can do but defend yourself, he has a new calculation to make. He cannot count on what you would prefer to do if he were advancing irresistibly; he must decide instead what he ought to do if you were incapable of anything but resisting him.
This is the position that Chiang Kai-shekgot himself into, and us with him, when he moved a large portion of his best troops to Quemoy. Evacuation under fire would be exceedingly diffi- cult; if attacked, his troops had no choice but to fight, and we probably had no choice but to assist them. It was undoubtedly a shrewd move from Chiang's point of view-coupling himself, and the United States with him, to Quemoy- and in fact if we had wanted to make clear to the Chinese Communists that Quemoy had to be defended if they attacked it, it would even have been a shrewd move also from our point of view.

Thisideaofburningbridges- of maneuveringintoaposition where one clearly cannot yield- conflicts somewhat, at least semantically, with the notion that what we want in our foreign policy is "the initiative. " Initiative is good if it means imagina- tiveness, boldness, new ideas. But the term somewhat disguises the fact that deterrence, particularly deterrence of anything less than mortal assault on the United States, often depends on get- ting into a position where the initiative is up to the enemy and it is he who has to make the awful decision to proceed to a clash.
In recent years it has become something of a principle in the Department of Defense that the country should have abundant "options" in its choice of response to enemy moves. The prin- ciple is a good one, but so is a contrary principle- that certain op- tions are an embarrassment. The United States government goes to great lengths to reassure allies and to warn Russians that it has eschewed certain options altogether, or to demonstrate that it could not afford them or has placed them out of reach. The commitment process on which alAmerican overseas deterrence depends- and on which all confidence within the alliance depends- is a process of surrendering and destroying options that we might have been expected to find too attractive in an emergency. Wenotonlygivethemupinexchangeforcommit- ments to us by our allies; we give them up on our own account to make our intentions clear to potential enemies. In fact, we do it not just to display our intentions but to adopt those inten- tions. If deterrence fails it is usually because someone thought he saw an "option" that the American government had failed to dispose of, a loophole that it hadn't closed against itself.
At law there is a doctrine of the "last clear chance. " It recog- nizes that, in the events leading up to an accident, there was some point prior to which either party could avert collision, some point after which neither could, and very likely a period between when one party could still control events but the other was helpless to turn aside or stop. The one that had the "last clear chance" to avert collision is held responsible. In strategy when both parties abhor collision the advantage goes often to the one who arranges the status quo in his favor and leaves to

the other the "last clear chance" to stop or turn aside. Xenophon understood the principle when, threatened by an attack he had not sought, he placed his Greeks with their backs against an impassable ravine. "I should like the enemy to think it is easy-going in every direction for him to retreat. " And when he had to charge a hill occupied by aliens, he "did not attack from every direction but left the enemy a way of escape, if he wanted to run away. " The "last chance" to clear out was left to the enemy when Xenophon had to take the initiative, but de- nied to himself when he wanted to deter attack, leaving his enemy the choice to attack or retire. 6
? ? ? ? ? ? An illustration of this principle- that deterrence often de- pends on relinquishing the initiative to the other side- may be found in a comparison of two articles that Secretary Dulles wrotein the 1950s. His articleinForeign AfSairs in 1954(based on the speech in which he introduced "massive retaliation") proposed that we should not let the enemy know in advancejust when and where and how we would react to aggression, but reserve for ourselves the decision on whether to act and the time, place, and scope of our action. In 1957 the Secretary
? ? wrote another article in Foreign Aflairs,this one oriented mainly toward Europe, in which he properly chose to reserve for the Soviets the final decision on all-out war. He discussed the need for more powerful NATO forces, especially "tactical" nuclear forces that could resist a non-nuclear Soviet onslaught at a level short of all-out war. He said:
In the future it may thus be feasible to place less reliance upon deterrence of vast retaliatory power. . . . Thus, in

contrast to the 1950decade, it may be that by the 1960decade the nations which are around the Sino-Soviet perimeter can possess an effective defense against full-scale conventional attack and thus confront any aggressor with the choice between failing or himself initiating nuclear war against the defending country. Thus the tables may be turned, in the sense that instead of those who are non-aggressive having to rely upon all-out nuclear retaliatory power for their protec- tion, would-be aggressors will be unable to count on a successful conventional aggression, but must themselves weigh the consequences of invoking nuclear war. 7
Former Secretary Dean Acheson was proposing the same principle (but attached to conventional forces, not tactical nuclear weapons) in remarkably similar language at about the same time in his book, Power and Diplomacy:
Suppose, now, that a major attack is mounted against a Western Europe defended by substantial and spirited forces including American troops. . . . Here, in effect, he (our potential enemy) would be making the decision for us, by compelling evidence that he had determined to run all risks and force matters to a final showdown, including (if it had not already occurred) a nuclear attack upon us. . . . A de- fense in Europe of this magnitude will pass the decision to risk everything from the defense to the offense. *
The same principle on the Eastern side was reflected in a remark often attributed to Khrushchev. It was typically agreed, especially at summit meetings, that nobody wanted a war. Khrushchev's complacent remark, based on Berlin's being on his side of the border, was that Berlin was not worth a war. As thestorygoes,hewasremindedthatBerlinwasnot worthawar to him either. "No," he replied, "but you are the ones that have

to cross a frontier. " The implication, I take it, was that neither of us wanted to cross that threshold just for Berlin, and if Berlin's location makes us the ones who have to cross the border, we are the ones who let it go though both of us are similarly fearful of War.
How do we maneuver into aposition so it is the other side that hastomakethatdecision? Wordsrarelydoit. Tohavetoldthe Soviets in the late 1940sthat, if they attacked, we were obliged to defend Europe might not have been wholly convincing. When the Administration asked Congress for authority to station Army divisions in Europe in peacetime, the argument was explicitly made that these troops were there not to defend against a superior Soviet army but to leave the Soviet Union in no doubt that the United States would be automatically in- volved in the event of any attack on Europe. The implicit argument was not that since we obviously would defend Europe we should demonstrate the fact by putting troops there. The reasoning was probably that, whether we wished to be or not, we could not fail to be involved if we had more troops being run over by the Soviet Army than we could afford to see defeated. Notions like "trip wire" or "plate glass window," though oversimplified, were attempts to express this role. And while "trip wire" is a belittling term to describe an army, the role is not a demeaning one. The garrison in Berlin is as fine a collection of soldiers as has ever been assembled, but excruciatingly small. What can 7,000 American troops do, or 12,000 Allied troops? Bluntly, they can die. They can die heroically, dramati- cally,andinamannerthatguaranteesthattheactioncannotstop there. They represent the pride, the honor, and the reputation of the United States government and its armed forces; and they can apparently hold the entire Red Army at bay. Precisely because there is no graceful way out if we wished our troops to yield ground,andbecauseWestBerlinistoosmallanareainwhichto ignoresmallencroachments,WestBerlinanditsmilitaryforces constitute one of the most impregnable military outposts of modemtimes.

mitments. The first is that if the commitment is ill defined and ambiguous- if we leave ourselves loopholes through which to exit- our opponent will expect us to be under strong temptation to make a graceful exit (or even a somewhat graceless one) and he may be right. The western sector of Berlin is a tightly defined piece of earth, physically occupied by Western troops: our com- mitmentiscrediblebecauseitisinescapable. (Thelittleenclave of Steinstucken is physically separate, surrounded by East Ger- man territory outside city limits, and there has been a certain amount of jockeying to determine how credible our commit- ment is to stay there and whether it applies to a corridor con- necting the enclave to the city proper. ) But our commitment to the integrity of Berlin itself, the entire city, was apparently weak or ambiguous. When the Wall went up the West was able to construe its obligation as not obliging forceful opposition. The Soviets probably anticipated that, if the West had a choice be- tween interpreting its obligation to demand forceful opposition
and interpreting the obligation more leniently, there would be a temptationtoelectthelenientinterpretation. Ifwecouldhave made ourselves obliged to knock down the wall with military force, the wall might not have gone up; not being obliged, we could be expected to elect the less dangerous course.
The second thing that Berlin illustrates is that, however precisely defined is the issue about which we are committed, it is oftenuncertainjustwhatwe are committed to do. The commit- ment is open-ended. Our military reaction to an assault on West Berlin is really not specified. We are apparently committed to holding the western sector of the city if we can; if we are pushed back, we are presumably committed to repelling the intruders and restoring the original boundary. If we lose the city, we are perhaps committed to reconquering it. But somewhere in this sequence of events things get out of hand, and the matter ceases to be purely one of restoring the status quo in Berlin. Military instabilities may arise that make the earlier status quo meaning- less. A costly reestablishment of the status quo might call for some sort of reprisal, obliging some counteraction in return. Just what would happen is a matter of prediction, or guess.
What we seem to be committed to is action of some sort com- mensurate with the provocation. Military resistance tends to de- velop a momentum of its own. It is dynamic and uncertain. What we threaten in Berlin is to initiate a process that may quickly get out of hand.

? The maneuver in Lebanon in 1958- the landing of troops in a developing crisis- though not one of the neatest political- military operations of recent times, represented a similar strat- egy. Whatever the military potential of the ten or twelve thousand troops that we landed in Lebanon- and it would de- pend on who might have engaged them, where, over what issue - they had the advantage that they got on the ground before any Soviet adventure or movement was under way. The landing might be described as a "preemptive maneuver. " From then on, any significant Soviet intervention in the affairs of Lebanon, Jordan, or even Iraq, would have substantially raised the likeli- hood that American and Soviet forces, or American and Soviet- supported forces, would be directly engaged.
? ? In effect, it was Khrushchev's turn to cross a border. Iraq or Jordan might not have been worth a war to either of us but by getting troops on the soil- or, as we used to say, the American
? flag -
we probably made it clear to the Kremlin that we could not gracefully retreat under duress. It is harder to retreat than not to land in the first place; the landing helped to put the next step up to the Russians.
Coupling Capabilities to Objectives: TheProcess of "Commitment"
In addition to getting yourself where you cannot retreat, there is a more common way of making a threat. That is to incur a political involvement, to get a nation's honor, obligation, and diplomatic reputation committed to a response. The Formosa resolutionof 1955,alongwith the military assistance agreement then signed by the United States and the National Government of the Republic of China, should probably be interpreted that way. It was not mainly a technique for reassuring Chiang Kai-shek that we would defend him, and it was not mainly a
? ? ? ? ? ? 50 ARMS AND INFLUENCE
THE ART OF COMMITMENT 51
quid pro quo for something he did for us. It was chiefly important as a move to impress a third party.
The primary audience for the congressional action was inside the Soviet bloc. The resolution, together with the treaty, was a ceremony to leave the Chinese and the Russians under no doubt that we could not back down from the defense of Formosa without intolerable loss of prestige, reputation, and leadership. We were not merely communicating an intention or obligation we already had, but actually enhancing the obligation in the pro- cess. Thecongressionalmessagewasnot,"Sinceweareobliged to defend Formosa, we may as well show it. " Rather: "In case we were not sufficiently committed to impress you, now we are. We hereby oblige ourselves. Behold us in the public ritual of getting ourselvesgenuinelycommitted. "
9. There is also sometimes available an internal technique of commitment. It is, in the words of Roger Fisher, "to weave international obligations into the domestic law of each country, so that by and large each government enforces the obligation against itself. " Fisher discussed it in relation to disarmament commitments; but it may apply to the use of force as well as to the renunciation of it. A Norwegian directive (Kgl res 10 Juni 1949) stipulates that, in event of armed attack, military officers are to mobilize whether or not the government issues the order, that orders for discontinuance issued in the name of the government shall be assumed false, and that resistance is to continue irrespective of enemy threats of retaliatory bombing. Similarly a Swiss order of April 1940, distributed to every soldier in his livret de service, declared that in event of attack the Swiss would fight and that any order or indication to the contrary, from any source, was to be considered enemy propaganda. The purposes appear to have been internal discipline and morale; but the possible contribution of such internal arrangements to deterrence, to the credibility of resistance, is worth considering. Many governments have had constitutional or informal provisions for increasing the authority of the armed forces in time of emergency, thus possibly shifting government authority in the direction of individuals and organizations whose motives to resist were less doubtful. As mentioned in an earlier footnote, legal automaticity has sometimes been proposed for the French nuclear force. Internal public opinion can be similarly manipulated to make accommodation unpopular. All of these techniques, if appreciated by the enemy to be deterred, are relevant to the process of commitment. They canalso,ofcourse,bequitedangerous. Fisher'sdiscussionisinhischapter,"Internal Enforcement of International Rules," Disarmament: Its Politics and Economics, Seymour Melman, ed. (Boston, American Academy of Arts and Sciences, 1962).
That kind of commitment is not to be had cheaply. If Con- gress passed such a resolution for every small piece of the world that it would like the Soviets to leave alone, it would cheapen the currency. A nation has limited resources, so to speak, in the things that it can get exceptionally concerned about. Political involvement within a country is not something that can be had for the price of a casual vote or a signature on a piece of paper.
Sometimes it comes about by a long process that may not even have been deliberately conceived. As far as I can tell, we had only the slightest commitment, if any, to assist India in case of attack by the Chinese or the Russians, if only because over the years the Indians did not let us incur a formal commitment. One of the lessons of November 1962may be that, in the face of anything quite as adventuresome as an effort to take over a country the size of India, we may be virtually as committed as if we had a mutual assistance treaty. We cannot afford to let the Soviets or Communist Chinese learn by experience that they can grab large chunks of the earth and its population without a genuine risk of violent Western reaction.
Our commitment to Quemoy, which gave us concern in 1955 and especially in 1958, had not been deliberately conceived; and it appeared at the time to be a genuine embarrassment. For reasons that had nothing to do with American policy, Quemoy hadbeensuccessfullydefendedbytheNationalistswhenChiang Kai-shek evacuated the mainland, and it remained in National- ist hands. By the time the United States assumed the Commit- ment to Formosa, the island of Quemoy stood as a ragged edge about which our intentions were ambiguous. Secretary Dulles in 1958 expressed the official view that we could not afford to vacate Quemoy under duress. The implication seemed to be that we had no genuine desire to take risks for Quemoy and mighthavepreferreditifQuemoyhadfallentotheCommunists in 1949;but our relations with Communist China were at stake once Quemoy became an issue. So we had a commitment that we might have preferred not to have. And in case that commit- ment did not appear firm enough, Chiang Kai-shek increased it

for us by moving enough of his best troops to that island, under conditions in which evacuation under attack would have been difficult, to make clear that he had to defend it or suffer military disaster,leavingituptotheUnitedStatestobailhimout.
Some of our strongest commitments may be quite implicit, though ritual and diplomacy can enhance or erode them. Com- mitments can even exist when we deny them. There is a lot of conjecture about what would happen if the NATO treaty lapsed after its initial twenty years. There has recently been some conjecture whether the developing community of Western Europe might be inconsistent with the Atlantic Alliance. It is sometimes argued that the Soviet Union would like Europe so self-reliant that the United States could ease itself out of its commitments to the present NATO countries. I think there is something in this- our commitment to Europe probably dimin- ishes somewhat if the NATO treaty legally goes out of force- but not much. Most of the commitment will still be there. We cannot afford to let the Soviets overrun West Germany or Greece, irrespective of our treaty commitments to Germany or to the rest of Western Europe.
I suspect that we might even recognize an implicit obligation to support Yugoslavia, perhaps Finland, in a military crisis. Any commitment we may have had toward Hungary was apparently not much. But Yugoslavia and Finland have not quite the status that Hungary had. (Conceivably we might cross the border first, under invitation, and leave it up to the Soviets to decide whether to incur the risk of engaging us. ) I wonder whether the Kremlin thinks that, if it should get genuinely impatient with Tito or if there were some kind of crisis of succession upon Tito's death, the Red Army could simply invade Yugoslavia or the Kremlin present an ultimatum to the country without any danger of a counter-ultimatum from us or another preemptive landing of troops as in Lebanon. I can only wonder; these are all matters of interpretation, both as to what our commitments really would prove to be and what the Soviets would believe them to be.
Actually, our commitment is not so much a policy as a prediction. We cannot have a clear policy for every con- tingency; there are too many contingencies and not enough hoursinthedaytoworkthemalloutinadvance. Ifonehad asked in October 1962 what American policy was for the contingency of a Communist Chinese effort to destroy the Indian Army, the only answer could have been aprediction of what the American government would decide to do in a contin- gency that probably had not been "staffed out" in advance. Policy is usually not a prefabricated decision; it is the whole set of motives and constraints that make a government's actions somewhat predictable.
In the Indian case, it turns out that we had a latent or implicit policy. For all I know, Mr. Nehru anticipated it for ten years. It is conceivable- though I doubt it- that one of the reasons Nehru was so contemptuous of the kinds of treaties that the Thai and Pakistani signed with us was that he felt that his own involvement with the West in a real emergency might be about as strong without the treaty as with it. It is interesting that any "commitment" we had to keep India from being conquered or destroyed by Communist China was not mainly a commitment totheIndiansortheirgovernment. We wanted to restrainCom- munist China generally; we wanted to give confidence to other governments in Asia; and we wanted to preserve confidence in our deterrent role all the way around the world to Europe. Military support to India would be a way of keeping an implicit pledge but the pledge was a general one, not a debt owed to the Indians. When a disciplinarian- police or other- intervenes toresistorpunishsomeone'sforbiddenintrusionorassault,any benefit to the victim of the intrusion or assault may be inciden- tal. He could even prefer not to be fought over; but if the issue is maintenance of discipline, he may not have much say in the matter.
This matter of prediction may have been crucial at the start of the Korean War. There has been a lot of discussion about whether we were or were not "committed" to the defense of South Korea. From what I have seen of the way the decision to
? ? ? ? ? ? ? ? 54
intervene was taken, first by participation of American military assistance forces, then by bombing, then with reinforcements, and finally with a major war effort, one could not confidently have guessed in May 1950 what the United States would do. One could only try to estimate the probable decision that the President would take, depending on what it looked like in Korea, who was advising him, and what else was going on in the world.
You will recall discussion about the importance of a particu- lar speech by Secretary of State Acheson in suggesting to the Soviets that South Korea was outside our defense perimeter. (As far as I know, there is no decisive evidence that the Russians, Chinese, or Koreans were particularly motivated by that statement. ) His stated position was essentially that we had a defense perimeter that excluded South Korea, that we had various other obligations, especially to the United Nations, that would cover acountry like South Korea. Apparently the Soviets (or Chinese, or whoever made the decision) miscalculated; they may have thought we were damning our commitment with faint praise. They got into an expensive war and a risky one and one that might have been even more dangerous than it was. They may have miscalculated because the language of deterrence, and an understanding of the commitment process in the nuclear era, had not had much time to develop yet. They may interpret better now- although the missile adventure in Cuba shows that the Soviets could still misread the signals (or the Americans
could still fail to transmit them clearly) a decade later.
And we seem to have misread the Chinese warnings during our advance toward the Yalu River. Allen Whiting has docu- mented a serious Chinese Communist attempt to warn the Americans that they would engage us militarily rather than let us occupy all of North Korea. l o Whatever we might have done had we understood them, we manifestly did not understand. The one thing we would not have done, had we received their warnings correctly, was to extend our forces as vulnerably as we did. We either did not get their message, did not comprehend it, or
10. China Crosses the Yalu (New York, Macmillan, 1960).
did not find it credible, though the Chinese Communists may have been doing the best they could to get the message to us and to make it credible. When communication fails, it is not easy to decide whether the transmitter is too weak for the receiver or the receiver too weak for the transmitter, whether the sender speaks the receiver' s language badly or the receiver misunderstands the sender's. Between the two of us, Americans and Commu- nist China, we appear to have suffered at least one communica- tion failure in each direction in 1950. "
The Interdependence of Commitments
The main reason why we are committed in many of these places is that our threats are interdependent. Essentially we tell the Soviets that we have to react here because, if we did not, they would not believe us when we say that we will react there.
By now our commitment to Berlin has become so deep and diffuse that most of us do not often have to think about whom our commitment is to. The reason we got committed to the de- fense of Berlin, and stayed committed, is that if we let the So- viets scare us out of Berlin we would lose face with the Soviets themselves. The reputation that most matters to us is our repu- tation with the Soviet (and Communist Chinese) leaders. It would be bad enough to have Europeans, Latin Americans, or Asians think that we are immoral or cowardly. It would be far worse to lose our reputation with the Soviets. When we talk about the loss of face that would occur if we backed out of For-
11. It is not easy to explain why the Chinese entered North Korea so secretly and so suddenly. Had they wanted to stop the United Nations forces at the level, say, of Pyongyang, to protect their own border and territory, a conspicuous early entry in force might have found the U. N. Command content with its accomplishment and in no mood to fight a second war, against Chinese armies, for the remainder of North Korea. They chose instead to launch a surprise attack, with stunning tactical advantages but no prospect of deterrence. It may have been a hard choice with the decision, finally, a pessimistic one; if so, it was probably a mistake. It may have been based on an overriding interest in the territorial integrity of a Communist North Korea; if so, accommodation was probably impossible anyhow. Or it may have been just a military obsession with tactical surprise, at the expense of all deterrence and diplomacy.

mosaunder duress, or out of Berlin, the loss of face that matters most is the loss of Soviet belief that we will do, elsewhere and subsequently, what we insist we will do here and now. Our deterrence rests on Soviet expectations.
This, I suppose, is the ultimate reason why we have to defend California- aside from whether or not Easterners want to. There is no way to let California go to the Soviets and make thembelieveneverthelessthatOregonandWashington,Florida and Maine, and eventually Chevy Chase and Cambridge cannot be had under the same principle. There is no way to persuade them that if we do not stop them in California we will stop them at the Mississippi (though the Mississippi is a degree less implausible than any other line between that river and, say, the continental divide). Once they cross a line into a new class of aggression, into a set of areas or assets that we always claimed we would protect, we may even deceive them if we do not react vigorously. Suppose we let the Soviets have California, and when they reach for Texas we attack them in full force. They could sue for breach of promise. We virtually told them they could have Texas when we let them into California; the fault is ours, for communicating badly, for not recognizing what we were conceding.
California is a bit of fantasy here; but it helps to remind us that the effectiveness of deterrence often depends on attaching to particular areas some of the status of California. The principle is at work all over the world; and the principle is not wholly under our own control. I doubt whether we can identify our- selveswithP&stan inquitethewaywecanidentifyourselves with Great Britain, no matter how many treaties we sign during the next ten years.
"To identify" is a complex process. It means getting the Soviets or the Communist Chinese to identify us with, say, Pakistan in such a way that they would lose respect for our commitments elsewhere if we failed to support Pakistan and we know they would lose that respect, so that we would have to support Pakistan and they know we would. In a way, it is the Soviets who confer this identification;but they do it through the
medium of their expectations about us and our understanding of their expectations. Neither they nor we can exercise full control over their expectations.
There is an interesting geographical difference in the Soviet and American homelands; it is hard to imagine a war so located that it could spill over by hot pursuit, by interdiction bombing, by inadvertent border violation, by local reprisal bombing, or evenbydeliberatebutlimitedgroundencroachmentintoAmeri- can territory. Our oceans may not protect us from big wars but they protect us from little ones. A local war could not impinge on California, involving it peripherally or incidentally through geographicalcontinuity,thewaytheKoreanWarcouldimpinge on Manchuria and Siberia, or the way Soviet territory could be impinged on by war in Iran, Yugoslavia, or Central Europe. One can argue about how far back toward Moscow an "interdic- tion campaign" of bombing might have to reach, or might safely reach, in case of a limited war in Central Europe; and there is no geographical feature- and few economic features - to present a sudden discontinuity at the Soviet border. A comparable question hardly arises for American participation in the same war; there is one discontinuity leading to submarine warfare on the high seas, and another, a great one, in going in- land to the railroad tracks that carry the freight to the Baltimore docks. The vehicles or vessels that would have to carry out the intrusion would furthermore be different in character from those involved in the "theater war. "

space violations even if no dirt is disturbed on their territory). The California principle actually can apply not only to terri- tories but to weapons. One of the arguments that has been made, and taken seriously, against having all of our strategic weapons at sea or in outer space or even emplaced abroad, is that the enemy might be able to attack them without fearing the kind of response that would be triggered by an attack on our homeland. If all missiles were on ships at sea, the argument runs, an attack on a ship would not be quite the same as an at- tack on California or Massachusetts; and an enemy might consider doing it in circumstances when he would not consider attacking weapons located on our soil. (An extreme form of the argument, not put forward quite so seriously, was that we ought to locate our weapons in the middle of population centers, so that the enemy could never attack them without arousing the massive response that he could take for granted if he struck our
cities. )
There is something to the argument. If in an Asian war we
flew bombers from aircraft carriers or from bases in an allied country, and an enemy attacked our ships at sea or our overseas bases, we would almost certainly not consider it the same as if we had flown the bombers from bases in Hawaii or California and he had attacked the bases in those states. If the Soviets had put nuclear weapons in orbit and we shot at them with rockets the results might be serious, but not the same as if the Soviets had put missiles on home territory and we shot at those missiles on their home grounds. Missiles in Cuba, though owned and manned by Russians, were less "nationalized" as a target than missiles in the U. S. S. R. itself. (One of the arguments made against the use of surface ships in a European Multilateral Force armed with long-range missiles was that they could be picked off by an enemy, possibly during a limited war in which the Multilateral Force was not engaged, possibly without the use of nuclear weapons by an enemy, in a way that would not quite provoke reprisal, and thus would be vulnerable in a way that homeland-based missiles would not be. )

liberately putting weapons outside our boundary, so that their military involvement would not tempt an attack on our home- land, or for keeping them within our boundaries so that an attack on them would appear the more risky. The point here isjust that there is a difference. Quemoy cannot be made part of California by moving it there, but weapons can.
Actually the all-or-nothing character of the homeland is not so complete. Secretary McNamara's suggestion that even a general war might be somewhat confined to military installa- tions, and that a furious attack on enemy population centers might be the proper response only to an attack on ours, implies that we do distinguish or might distinguish different parts of our territory by the degree of warfare involved. And I have heard it argued that the Soviets, if they fear for the deterrent security of their retaliatory forcesinapurely"military"warthattheAmeri- cans might initiate, may actually prefer a close proximity of their missiles to their cities to make the prospect of a "clean" strategic war, one without massive attacks on cities, less prom- ising- to demonstrate that there would remain little to lose, after an attack on their weapons, and little motive to confine their response to military targets. The policy would be a dangerous one if there were much likelihood that war would occur, but its logic has merit.
Discrediting an Adversary's Commitments
The Soviets have the same deterrence problem beyond their bordersthatwehave. InsomewaystheWesthashelpedthemto solve it. All kinds of people, responsible and irresponsible, intelligent and unenlightened, European and American, have raised questions about whether the United States really would use its full military force to protect Western Europe or to retaliate for the loss of Western Europe. Much more rarely did I hear anyone question- at least before about 1963- whether the Soviets would do likewise if we were provoked to an attack against the homeland of Communist China.

them- what we find difficult, namely, to persuade the world that the entire area of their alliance is part of an integral bloc. In the West we talked for a decade- until the Sino-Soviet schism became undeniable- about the Sino-Soviet bloc as though every satellite were part of the Soviet system, and as though Soviet determination to keep those areas under their control was so intense that they could not afford to lose any of it. We often acted as though every part of their sphere of influencewasa"California.

If we always treat China as though it is a Soviet California, we tend to make it so.
