or if the government controls prices. Perfect competition, complete collusion, absolute control: These different causes produce identical results. From unifor- mity of outcomes one cannot infer that the attributes and the interactions of the parts of a system have remained constant. Structure may determine outcomes aside from changes at the level of the units and aside from the disappearance of some of them and the emergence of others. Different "causes" may produce the same effects; the same "causes" may have different consequences. Unless one knows how a realm is organized, one can hardly tell the causes from the effects.
The effect of an organization may predominate over the attributes and the interactions of the elements within it. A system that is independent of initial con- ditions is said to display equifinality. If it does, lithe system is then its own best explanation, and the study of its present organization the appropriate meth- odology" (Watzlawick, et al. , 1967, p. 129; cf. p. 32). If structure influences with- out determining, then one must ask how and to what extent the structure of a realm accounts for outcomes and how and to what extent the units account for outcomes. Structure has to be studied in its own right as do units. To claim to be following a systems approach or to be constructing a systems theory requires one to show how system and unit levels can be distinctly defined. Failure to mark and preserve the distinction between structure, on the one hand, and units and pro- cesses, on the other, makes it impossible to disentangle causes of different sorts and to distinguish between causes and effects. Blurring the distinction between the different levels of a system has, I believe, been the major impediment to the development of theories about international politics. The next chapter shows how to define political structures in a way that makes the construction of a sys- tems theory possible.
Political Structures
We learned in Chapters 2, 3, and 4 that international-political outcomes
be explained reductively. We found in Chapter 3 that even avowedly approaches mingle and confuse systems-level with unit-level causes. on theories that follow the general-systems model, we concluded at once that Inter- national politics does not fit the model closely enough to make the model useful and that only through some sort of systems theory can international politics be understood. To be a success, such a theory has to show how international politics can be conceived of as a domain distinct from the economic, social, and other international domains that one may conceive of. To mark international-political systems off from other international systems, and to distinguish systems-level from unit-level forces, requires showing how political structures are generated and how they affect, and are affected by, the units of the system. How can we conceive of international politics as a distinct system1 What is it that intervenes between interacting units and the results that their acts and interactions
To answer these questions, this chapter first examines the concept of SOCIal struc-
ture and then defines structure as a concept appropriate for national and for inter- national politics.

Definitions of structure must leave aside, or abstract from, the characteris- tics of units their behavior, and their interactions. Why must those obviously important be omitted1 They must be omitted so that we can distinquish between variables at the level of the units and variables at the level of the system.

Anarchic Structures and Balances of Power
Two tasks remain: first, to examine the characteristics of anarchy and the expectations about outcomes associated with anarchic realms; second, to examine the ways in which expectations vary as the structure of an anarchic sys- tem changes through changes in the distribution of capabilities across nations. The second task, undertaken in Chapters 7, 8, and 9, requires comparing differ- ent international systems. The first, which I now turn to, is best accomplished by drawing some comparisons between behavior and outcomes in anarchic and hier- archic realms.

1. VIOLENCE A T HOME AND ABROAD
The state among states, it is often said, conducts its affairs in the brooding shadow of violence. Because some states may at any time use force, all states must be prepared to do so-or live at the mercy of their militarily more vigorous neighbors. Among states, the state of nature is a state of war. This is meant not in the sense that war constantly occurs but in the sense that, with each state deciding for itself whether or not to use force, war may at any time break out. Whether in the family, the community, or the world at large, contact without at least occasional conflict is inconceivable; and the hope that in the absence of an agent to manage or to manipulate conflicting parties the use of force will always be avoided cannot be realistically entertained. Among men as among states, anarchy, or the absence of government, is associated with the occurrence of violence.
The threat of violence and the recurrent use of force are said to distinguish international from national affairs. But in the history of the world surely most rulers have had to bear in mind that their subjects might use force to resist or
Anarchic Orders and Balances of Power 103
overthrow them. If the absence of government is associated with the threat of violence, so also is its presence. A haphazard list of national tragedies illustrates the point all too well. The most destructive wars of the hundred years following the defeat of Napoleon took place not among states but within them. Estimates of deaths in China's Taiping Rebellion, which began in 1851 and lasted 13 years, range as high as 20 million. In the American Civil War some 600 thousand people lost their lives. In more recent history, forced collectivization and Stalin's purges eliminated five million Russians, and Hitler exterminated six million Jews. In some Latin American countries, coups d'etats and rebellions have been normal features of national life. Between 1948 and 1957, for example, 200 thousand Colombians were killed in civil strife. In the middle 19705 most inhabitants of Idi Amin's Uganda must have felt their lives becoming nasty, brutish, and short, quite as in Thomas Hobbes's state of nature. If such cases constitute aberrations, they are uncomfortably common ones. We easily lose sight of the fact that struggles to achieve and maintain power, to establish order, and to contrive a kind of justice within states, may be bloodier than wars among them.
If anarchy is identified with chaos, destruction, and death, then the distinc- tion between anarchy and government does not tell us much. Which is more pre- carious: the life of a state among states, or of a government in relation to its sub- jects? The answer varies with time and place. Among some states at some times, the actual or expected occurrence of violence is low. Within some states at some times, the actual or expected occurrence of violence is high. The use of force, or the constant fear of its use, are not sufficient grounds for distinguishing inter- national from domestic affairs. If the possible and the actual use of force mark both national and international orders, then no durable distinction between the two realms can be drawn in terms of the use or the nonuse of force. No human order is proof against violence.
To discover qualitative differences between internal and external affairs one must look for a criterion other than the occurrence of violence. The distinction between international and national realms of politics is not found in the use or the nonuse of force but in their different structures. But if the dangers of being violently attacked are greater, say, in taking an evening stroll through downtown Detroit than they are in picnicking along the French and German border, what practical difference does the difference of structure make? Nationally as internationally, contact generates conflict and at times issues in violence. The dif- ference between national and international politics lies not in the use of force but in the different modes of organization for doing something about it. A govern- ment, ruling by some standard of legitimacy, arrogates to itself the right to use force-that is, to apply a variety of sanctions to control the use of force by its subjects. If some use private force, others may appeal to the government. A government has no monopoly on the use of force, as is all too evident. An effec-

Chapter 6 compared national and international systems and showed how behav- ior and outcomes vary from one system to another. Chapter 7, 8, and 9 compare different international systems and show how behavior and outcomes vary in systems whose ordering principles endure but whose structures vary through changes in the distribution of capabilities across states. The question posed in this chapter is whether we should prefer larger or smaller numbers of great powers. Part I carries the theory further. Part II moves from theory to practice. *

1. COUNTING POLES AND MEASURING POWER
How should we count poles, and how can we measure power? These questions must be answered in order to identify variations of structure. Almost everyone agrees that at some time since the war the world was bipolar. Few seem to believe that it remains so. For years Walter Lippmann wrote of the bipolar world as being perpetually in the process of rapidly passing away (e. g. , 1950 and 1963). Many others now carry on the tradition he so firmly established. To reach the conclu- sion that bipolarity is passing, or 'past, requires some odd counting. The inclina- tion to count in funny ways is rooted in the desire to arrive at a particular answer. Scholars feel a strong affection for the balance-of-power world of Metternich and Bismarck, on which many of their theoretical notions rest. That was a world in which five or so great powers manipulated their neighbors and maneuvered for advantage. Great powers were once defined according to their capabilities. Stu- dents of international politics now seem to look at other conditions. The ability or inability of states to solve problems is said to raise or lower their rankings. The

tude was well expressed by Trotsky, who, when asked what he would do as foreign minister, replied, "I will issue some revolutionary proclamations to the peoples and then close up the joint" (quoted in Von Laue 1963, p. 235). In a com- petitive arena, however, one party may need the assistance of others. Refusal to play the political game may risk one's own destruction. The pressures of competi- tion were rapidly felt and reflected in the Soviet Union's diplomacy. Thus Lenin, sending foreign minister Chicherin to the Genoa Conference of 1922, bade him farewell with this caution: "Avoid big words" (quoted in Moore 1950, p. 204). Chicherin, who personified the carefully tailored traditional diplomat rather than the simply uniformed revolutionary, was to refrain from inflammatory rhetoric
for the sake of working deals. These he successfully completed with that other pariah power and ideological enemy, Germany.
The close juxtaposition of states promotes their sameness through the disad- vantages that arise from a failure to conform to successful practices. It is this "sameness," an effect of the system, that is so often attributed to the acceptance of so-called rules of state behavior. Chiliastic rulers occasionally come to power. In power, most of them quickly change their ways. They can refuse to do so, and yet hope to survive, only if they rule countries little affected by the competition of states. The socialization of nonconformist states proceeds at a pace that is set by the extent of their involvement in the system. And that is another testable statement.
The theory leads to many expectations about behaviors and outcomes. From the theory, one predicts that states will engage in balancing behavior, whether or not balanced power is the end of their acts. From the theory, one predicts a strong tendency toward balance in the system. The expectation is not that a balance, once achieved, will be maintained, but that a balance, once disrupted, will be restored in one way or another. Balances of power recurrently form. Since the theory depicts international politics as a competitive system, one predicts more
specifically that states will display characteristics common to competitors: namely, that they will imitate each other and become socialized to their system. In this chapter, I have suggested ways of making these propositions more specific and concrete so as to test them. In remaining chapters, as the theory is elaborated and refined, additional testable propositions will appear.

chessboard is accurately described.
So far I have shown that smaller are better than larger numbers, at least for
those states at the top. Defining the concept, and examining the economics, of interdependence did not establish just which small number is best of all. We could not answer that question because economic interdependence varies with the size of great powers and their size does not correlate perfectly with their number. In
the next chapter, examination of military interdependence leads to an exact answer.
Structural Causes and Military Effects
Chapter 7 showed why smaller is better. To say that few are better than many is not to say that two is best of all. The stability of pairs-of corporations, of political parties, of marriage partners-has often been appreciated. Although most students of international politics probably believe that systems of many great powers would be unstable, they resist the widespread notion that two is the best of small numbers. Are they right to do so? For the sake of stability, peace, or whatever, should we prefer a world of two great powers or a world of several or more? Chapter 8 will show why two is the best of small numbers. We reached some conclusions, but not that one, by considering economic interdependence. Problems of national security in multi- and bipolar worlds do clearly show the advantages of having two great powers, and only two, in the system.
I
To establish the virtues of two-party systems requires comparing systems of dif- ferent number. Because the previous chapter was concerned only with systems of small and of still smaller numbers, we did not have to consider differences made by having two, three, four, or more principal parties in a system. We must do so now. By what criteria do we determine that an system changes, and conversely, by what criteria do we say that a system is stable? Political scientists often lump different effects under the heading of stability. I did this in 1964 and 1967 essays, using stability to include also peacefulness and the effective management of international affairs, which are the respective concerns of this chapter and the next one. It is important, I now believe, to keep different effects separate so that we can accurately locate their causes.
Anarchic systems are transformed only by changes in organizing principle and by consequential changes in the number of their principal parties. To say that an international-political system is stable means two things: first, that it remains

If power does not reliably bring control, what does it do for you? Four things, primarily. First, power provides the means of maintaining one's autonomy in the face of force that others wield. Second, greater power permits wider ranges of action, while leaving the outcomes of action uncertain. These two advantages we have discussed. The next two require elaboration.
Third, the more powerful enjoy wider margins of safety in dealing with the less powerful and have more to say about which games will be played and how. Duncan and Schnore have defined power in ecological terms as lithe ability of one cluster of activities or niches to set the conditions under which others must function" (1959, p. 139). Dependent parties have some effect on independent ones, but the latter have more effect on the former. The weak lead perilous lives. As Chrysler's chairman, John Riccardo, remarked: "We've got to be right. The smaller you are, the more right you've got to be" (Salpukas, March 7, 1976, III, p. 1). General Motors can lose money on this model or that one, or on all of them, for quite a long time. Chrysler, if it does so, goes bankrupt. Be they cor- porations or states, those who are weak and hard pressed have to be careful. Thus with the following words Nguyen Van Thieu rejected the agreement for
ending the war in Vietnam that Kissinger, the ally, and Le Duc Tho, the enemy, had made in October of 1972:
You are a giant, Dr. Kissinger. So you can probably afford the luxury of being easy in this agreement. I cannot. A bad agreement means nothing to you. What is the loss of South Vietnam if you look at the world's map1 Just a speck. The loss of South Vietnam may even be good for you. It may be good to contain China, good for your world strategy. But a little Vietnamese doesn't play with a strategic map of the world. For us, it isn't a question of choosing between Mos- cow and Peking. It is a question of choosing between life and death (quoted in Stoessinger 1976, p. 68).
Weak states operate on narrow margins. Inopportune acts, flawed policies, and mistimed moves may have fatal results. In contrast, strong states can be inatten- tive; they can afford not to learn; they can do the same dumb things over again. More sensibly, they can react slowly and wait to see whether the apparently threatening acts of others are truly so. They can be indifferent to most threats because only a few threats, if carried through, can damage them gravely. They can hold back until the ambiguity of events is resolved without fearing that the moment for effective action will be lost.
Fourth, great power gives its possessors a big stake in their system and the ability to act for its sake. For them management becomes both worthwhile and possible. To show how and why managerial tasks are performed internationally is the subject of this chapter. In self-help systems, as we know competing parties consider relative gains more important than absolute ones. Absolute gains become more important as competition lessens. Two conditions make it possible for the United States and the Soviet Union to be concerned less with scoring rela- tive gains and more with making absolute ones. The first is the stability of two- party balances, a stability reinforced by second-strike nuclear weapons. Where a first-strike capability is almost as difficult to imagine as to achieve, gains and losses need not be so carefully counted. The second condition is the distance between the two at the top and the next most powerful states, a distance that removes the danger of third states catching up. The United States gained relative- ly when OPEC multiplied oil prices by five between 1973 and 1977 (cf. above, pp. 153-55). The other noncommunist industrial countries suffered more than we did. At times it was hinted that, for this reason, the United States more readily acquiesced in OPEC's actions. In the past, with many competing powers, one might have credited the aspersion, but not now. In a self-help system, when the great-power balance is stable and when the distribution of national capabilities is severely skewed, concern for absolute gains may replace worries about relative ones. Those who are unduly favored can lead in, or lend themselves to, collective efforts even though others gain disproportionately from them.
In this chapter, I first show how managing is done internationally despite the difficulties, and then consider three tasks that the managers may perform. We shall, as usual, notice how tasks are differently performed as the number of their performers varies.

Duncan and Schnore have defined power in ecological terms as lithe ability of one cluster of activities or niches to set the conditions under which others must function" (1959, p. 139). Dependent parties have some effect on independent ones, but the latter have more effect on the former. The weak lead perilous lives. As Chrysler's chairman, John Riccardo, remarked: "We've got to be right. The smaller you are, the more right you've got to be" (Salpukas, March 7, 1976, III, p. 1). General Motors can lose money on this model or that one, or on all of them, for quite a long time. Chrysler, if it does so, goes bankrupt. Be they cor- porations or states, those who are weak and hard pressed have to be careful. Thus with the following words Nguyen Van Thieu rejected the agreement for
ending the war in Vietnam that Kissinger, the ally, and Le Duc Tho, the enemy, had made in October of 1972:
You are a giant, Dr. Kissinger. So you can probably afford the luxury of being easy in this agreement. I cannot. A bad agreement means nothing to you. What is the loss of South Vietnam if you look at the world's map1 Just a speck. The loss of South Vietnam may even be good for you. It may be good to contain China, good for your world strategy. But a little Vietnamese doesn't play with a strategic map of the world. For us, it isn't a question of choosing between Mos- cow and Peking. It is a question of choosing between life and death (quoted in Stoessinger 1976, p. 68).
Weak states operate on narrow margins. Inopportune acts, flawed policies, and mistimed moves may have fatal results. In contrast, strong states can be inatten- tive; they can afford not to learn; they can do the same dumb things over again. More sensibly, they can react slowly and wait to see whether the apparently threatening acts of others are truly so. They can be indifferent to most threats because only a few threats, if carried through, can damage them gravely. They can hold back until the ambiguity of events is resolved without fearing that the moment for effective action will be lost.
Fourth, great power gives its possessors a big stake in their system and the ability to act for its sake. For them management becomes both worthwhile and possible. To show how and why managerial tasks are performed internationally is the subject of this chapter. In self-help systems, as we know competing parties consider relative gains more important than absolute ones. Absolute gains become more important as competition lessens. Two conditions make it possible for the United States and the Soviet Union to be concerned less with scoring rela- tive gains and more with making absolute ones. The first is the stability of two- party balances, a stability reinforced by second-strike nuclear weapons. Where a first-strike capability is almost as difficult to imagine as to achieve, gains and losses need not be so carefully counted. The second condition is the distance between the two at the top and the next most powerful states, a distance that removes the danger of third states catching up. The United States gained relative- ly when OPEC multiplied oil prices by five between 1973 and 1977 (cf. above, pp. 153-55). The other noncommunist industrial countries suffered more than we did. At times it was hinted that, for this reason, the United States more readily acquiesced in OPEC's actions. In the past, with many competing powers, one might have credited the aspersion, but not now. In a self-help system, when the great-power balance is stable and when the distribution of national capabilities is severely skewed, concern for absolute gains may replace worries about relative ones. Those who are unduly favored can lead in, or lend themselves to, collective efforts even though others gain disproportionately from them.
In this chapter, I first show how managing is done internationally despite the difficulties, and then consider three tasks that the managers may perform. We shall, as usual, notice how tasks are differently performed as the number of their performers varies.

In the relations of states, with competition unregulated, war occasionally occurs.
