But despite these assaults on free trade,two important lines of argument survive that link it firmly to declining incentives for states to use force in their relations with each other.These arguments are first,that free trade substantially reduces the number of targets to which force might appropriately be applied in the pursuit of state interests;and second,that it increases the vulnerability of actors,therefore making them disinclined to entertain the risks of resorting to force. These arguments rest on direct structural consequences of free trade.Their logic therefore stands independent of all the controversies that surround the other aspects of the liberal case.Furthermore,these arguments are on the international rather than on the national level.Their impact requires only that states be willing to implement free-trade policy.The arguments thus allow a considerable degree of flexibility in the domestic structure of states, a feature that fits well with the actual composition of the liberal economy since 1945 and no doubt accounts for some of the wide influence of the liberal case in the postwar era. Given the controversy attending the other aspects of the liberal case,es- pecially the highly ideological debate surrounding the character of capitalist democracies,these two arguments have provided the case's backbone in the period since 1945.The balance of the liberal case has thus changed dra- matically.In the classical period the absence of democracy caused the weight of argument to be focused on the domestic structure of states.But in the modern period both the predominance of democracy in the core states and the disputes about its political effects have largely shifted the burden of the case onto arguments at the international level. It is important to note that these arguments do not require perfect free trade.The modern liberal case requires only that the level of restriction on trade be sufficiently low to allow the principle of comparative advantage to operate effectively.When that condition is met,both the separation of wealth from territory and the increase in vulnerability can come into play.The logic does not require free movement of labor or capital,but the relatively free movement of money is an important factor in maintaining trade.Thus a highly imperfect free-trade system will still count as liberal.

The liberal claim to separate the pursuit of wealth from the control of territory marks a major distinction between liberal and mercantilist systems, and it is the basis for much of the connection between free trade and peace. When wealth and welfare are directly associated with territorial control,force has a high utility within the economic sphere.That this high utility is likely to lead to actual use of force is compellingly evinced by the history of both the 1930s and the long period of classical mercantilism that preceded the 19th-century Pax Britannica.It is this contrast with the mercantilist system that makes the role of free trade so important.Liberal economics can be offered not only as being positively conducive to peace in its own right but also as being a specific cure for the problems of mercantilism. The second argument-that free trade increases the vulnerability of states and therefore reduces their incentives to resort to force-is most frequently found in the literature on interdependence.'2 The complex network of de- pendencies that results from free trade requires individual actors to depend increasingly on the availability of both key imports and export markets for indigenous products.This dependence on the larger pattern of exchange relations means that states become vulnerable.Participation in a liberal economy automatically erodes the pursuit of economic self-reliance. Because states in a liberal economy are more vulnerable,the use of force declines for two reasons.First,instruments other than military ones become a more effective,appropriate,reliable,and economical means of conducting international relations.Second,because states are dependent across a range of relationships,their fear of self-damage will incline them to refrain from using force even when the issues are not economic ones. These effects are amplified when the liberal system has been in operation for many years and its higher levels of welfare have become institutionalized in domestic political life.When high levels of domestic welfare are dependent on the maintenance of liberal economic relations,governments become es- pecially vulnerable to economic pressure,as Britain discovered during the 11.Klaus Knorr,Power and Wealth (London:Macmillan,1973),p.196,and"On the Inter- national Uses of Military Force in the Contemporary World,"Orbis 21,1(1977),pp.7-9,16; Robert Keohane and Joseph Nye,Power and Interdependence (Boston:Little,Brown,1977), p.28;Robert W.Tucker,The Inequality of Nations (London:Robertson,1977),pp.174-75; Robert J.Art,"To What Ends Military Power?"International Security 4,4(1980),pp.31-35; and Wolfram Hanrieder,"Dissolving International Politics:Reflections on the Nation-State," American Political Science Review 72,4 (1978),pp.1279-80. 12.See,for example,Keohane and Nye,Power and Interdependence,pp.28-29;Tucker, Inequality of Nations,pp.174-75;and Robert Gilpin,U.S.Power and the Multinational Cor- poration (London:Macmillan,1976),p.227

It is this contrast with the mercantilist system that makes the role of free trade so important. Liberal economics can be offered not only as being positively conducive to peace in its own right but also as being a specific cure for the problems of mercantilism. The second argument-that free trade increases the vulnerability of states and therefore reduces their incentives to resort to force-is most frequently found in the literature on interdependence.'2 The complex network of dependencies that results from free trade requires individual actors to depend increasingly on the availability of both key imports and export markets for indigenous products. This dependence on the larger pattern of exchange relations means that states become vulnerable. Participation in a liberal economy automatically erodes the pursuit of economic self-reliance. Because states in a liberal economy are more vulnerable, the use of force declines for two reasons. First, instruments other than military ones become a more effective, appropriate, reliable, and economical means of conducting international relations. Second, because states are dependent across a range of relationships, their fear of self-damage will incline them to refrain from using force even when the issues are not economic ones. These effects are amplified when the liberal system has been in operation for many years and its higher levels of welfare have become institutionalized in domestic political life.

Both economic activity and political expectation structure themselves around its continuance,and withdrawal becomes increasingly costly and painful.3 Knowledge of this situation constrains governments from using military in- struments for any except the most basic objectives. But if we take these two strong international-level arguments and try to use them to explain the long peace since 1945,a large anomaly emerges, namely,that the liberal system is not universal in extent.If the liberal eco- nomic system is only partially applicable to the international system as a whole,its ability to explain a period of relative harmony must be corre- spondingly limited. The most obvious consequence of nonuniversality is the inevitable rela- tionship of force between the liberal subgroup and any other large international power.Since actors outside the liberal sphere cannot be assumed to be subject to its logic,the liberal subgroup must play the balance-of-power game in order to ensure its own security.The character of that larger game will clearly determine the overall pattern of peace and war to a much greater extent than will the internal dynamic of the liberal subsystem. Nonuniversality also has serious consequences for the liberal case on the domestic level.Two domestic lines of argument relate to those stemming from interdependence.First,it can be argued that the pressure of economic competition causes states within a liberal system to favor resource allocations to investment rather than to defense.4 Second,it can be argued that liberal economics sustains individualist,materialist,and humanist values,which erode the will of the state to use force.(A more cynical version of this second argument holds that the democratic mass politics that arises from these values forces governments to favor resource allocations to civil consumption over defense.)To the extent that these arguments are true,states within a liberal system will consistently tend to underprovide themselves with military capability. This domestic liberal dynamic traps governments within a liberal subgroup in a permanent policy dilemma.They must resolve on a continuing basis the contradiction between the internal pressure to minimize their relationship with force and the external pressure to play the balance of power.If domestic liberalism leads to underprovision or underuse of force,governments risk the external destruction of their values.But if they overreact to external threat,they risk the internal destruction of liberal values,and possibly of 13.Edward L.Morse,"Interdependence in World Affairs,"in J.N.Rosenau,K.W.Thompson, and G.Boyd,eds.,World Politics (New York:Free Press,1976),p.676;Knorr,Power and Wealth,p.9;C.A.Murdock,"Economic Factors as Objects of Security,"in Klaus Knorr and Frank Trager,eds.,Economic Issues and National Security (Lawrence:Regents Press of Kansas, 1977),pp.70-72;and Hanrieder,"Dissolving International Politics,"pp.1279-80. 14.For discussion,see Gilpin,War and Change,chap.4

The principal area of decline in the use of force since 1945 has been the absence of war among the major powers.More arguably,there are grounds for thinking that decolonization has reduced the use of force in relations between North and South. These two categories of decline have been in what Robert Art calls the "physical"use of force:war or direct violence between states.But in what he calls the"peaceful"use of force,the picture is quite different.s Deterrence has offset the decline in war among the major powers,by substituting a “peaceful'use for a“physical'”one.Almost everywhere else the use of military power short of fighting flourishes in the traditional fashion.Con- sidering just"peaceful"uses of force,it is only among relations within the Western group of states that one can identify a major decline.Hardly any of these states deploy their forces against each other,and hardly any of them view others in the group as a significant source of military threat.16 Thus,while there has been no uniform decline in the use of force,there have been some significant sectional declines.7 By far the largest decline is centered on the Western states,particularly in relations among them but 15.Art,"To What Ends,"p.5.Thomas Schelling and Robert Osgood have also made extensive use of a very similar distinction.See Schelling,Arms and Influence (New Haven:Yale University Press,1966),chap.1,and Osgood and Robert W.Tucker,Force,Order and Justice (Baltimore:Johns Hopkins Press,1967),pt.I,chaps.1 and 3. 16.Greece and Turkey are notable exceptions to this generalization. 17.For the disutility view,see Walter Millis,"The Uselessness of Military Power,"in William Coplin and Charles Kegley Jr.,eds.,A Multi-Method Introduction to International Politics (Chicago:Markham,1971),pp.114-27.Public doubts about the utility of force arose both from the paralysis of deterrence and from America's debacle in Vietnam.They stimulated a host of rebuttals,most of which focused on the continued utility of"peaceful"uses of force despite increased restraints on its"physical"use.See Art,"To What Ends,"pp.27-29;Michael Howard,"Military Power and International Order,"International Affairs 40,3(1964),p.405; Osgood and Tucker,Force,Order and Justice,p.179;Edward A.Kolodziej and Robert Harkavy, "Developing States and the International Security System,"Journal of International Afairs 34,1 (1980),p.59;Laurence Martin,"The Changed Role of Military Power,"International Afairs special issue (November 1970),p.107.For a useful overview of the debate,see Knorr, “On the International Uses,”pp.5-27
