At the same time, theories that trace the forces of international relations to a single source were increasingly viewed as unsatisfactory. The struggle for power, for example, was accepted as a fact in past and current international politics, but attempts to make all other factors subordinate to or dependent upon power were thought to exclude too much of what is important and interesting in international relations. Similar assessments were made of the theory that asserts that the character of a nation—and hence the character of its participation in international relations—is determined by its child-rearing practices, as well as of the Marxist theory that international relations are solely the historical expression of class struggle. The general attitude of the behavioral decade was that the facts of international relations are multidimensional and therefore have multiple causes. This conclusion supported, and in turn was supported by, the related view that an adequate account of these facts could not be provided in a single integrated theory and that multiple separate theories were required instead. By the 1960s, for example, studies of international conflict had come to encompass a number of different perspectives, including the realist theory of the struggle for power between states and the Marxist notion of global class conflict, as well as other explanations. At the same time, conflict theory coexisted with economic and political integration theory and game theory, each of which approached the phenomena of international conflict from a distinct perspective.

In keeping with the multiple-theory approach, by the end of the behavioral decade there was a growing consensus that the study of international relations should encompass both quantitative and qualitative analyses. Whereas quantitative methodologies were recognized as useful for measuring and comparing international phenomena and identifying common features and patterns of behaviour, qualitative analyses, by focusing on one case or a comparison of cases involving specific research questions, hypotheses, or categories, were thought to provide a deeper understanding of what is unique about political leaders, nations, and important international events such as World War II and the Cold War. The use of quantitative analysis in international relations studies increased significantly in the decades after the 1960s. This was a direct result of advances in computer technology, both in the collection and retrieval of information and in the analysis of data. When computers were introduced in international relations studies, it was not readily apparent how best to exploit the new technology, partly because most earlier studies of international relations were set forth in narrative or literary form and partly because many of the phenomena examined were not easily quantifiable. Nevertheless, exploratory quantitative studies were undertaken in a number of directions. A growing body of studies, for example, developed correlations between phenomena such as alliances and the outbreak or deterrence of war, between levels of political integration and levels of trade, communication, and mobility of populations, between levels of economic development and internal political stability, and between levels of internal violence and participation in international conflicts.

The later 20th century: Foreign policy and international systems. The influence of behaviourism helped to organize the various theories of international relations and the discipline into essentially two principal parts, or perspectives: the foreign-policy perspective and the international-system-analysis perspective. Within each of these perspectives there developed various theories. The foreign-policy perspective, for example, encompasses theories about the behaviour of individual states or categories of states such as democracies or totalitarian dictatorships, and the international-system-analysis perspective encompasses theories of the interactions between states and how the number of states and their respective capabilities affect their relations with each other. The foreign-policy perspective also includes studies of the traits, structures, or processes within a national society or polity that determine or influence how that society or polity participates in international relations. One such study, known as the decision-making approach, analyzes the information that decision makers use, their perceptions and motivations, the influence on their behaviour of public opinion, the organizational settings in which they operate, and their intellectual, cultural, and societal backgrounds. Studies that analyze the relations between the wealth, power, or technological level of a state and its international status and role provide other illustrations of the foreign-policy perspective.

Page 134

Comparative foreign-policy analysis first appeared during the mid-1960s. By comparing the domestic sources of external conduct in different countries, using standard criteria of data selection and analysis, this approach seeks to develop generalized accounts of foreign-policy performance, including theories that explore the relationship between the type of domestic-external linkage a country displays and its political and economic system and level of social development. Some research also has explored the extent to which certain patterns of behaviour, such as violent demonstrations or protests, may spread from one state to another. Whereas foreign-policy analysis concentrates on the units of the international system, international-system analysis is concerned with the structure of the system, the interactions between its units, and the implications for peace and war, or cooperation and conflict, of the existence of different types of states. The term interactions suggests challenge and response, give and take, move and countermove, or inputs and outputs. Diplomatic histories feature narratives of action and response in international situations and attempt to interpret the meanings of the exchanges. Balance-of-power theory, which asserts that states act to protect themselves by forming alliances against powerful states or coalitions of states, is another example of the international-system perspective. Still other examples include explanations and descriptions of bargaining in international negotiations and studies of arms races and other escalating action-reaction processes.

The general-system perspective: The so-called general-system perspective on international relations, which attempts to develop a comprehensive understanding of the dynamics of the relations between states, may be compared to the map of a little-explored continent. Outlines, broad features, and a continental delineation are not in question, but everything else remains in doubt, is subject to controversy, and awaits exploration. The Russian-born mathematician and biologist Anatol Rapoport once remarked that general-system theory is not really a theory but instead "a program or a direction in the contemporary philosophy of science." The concept of a system can be used to study patterns of interaction within and between units of foreign-policy decision making; by exploring such patterns, one can determine how foreign policies are formulated and how states or other units interact with or are related to each other, as opposed to how they interact with outside units. The members of a family, for example, interact with each other in ways that clearly differ from the ways in which they interact with other persons, such as colleagues in a place of employment or fellow members of a church. Although systems are definable in terms of units that exhibit certain patterns of interaction with each other, there also may be interaction between a system and its subsystems. A national political system, for example, may interact with subsystems such as interest groups, the media, or public opinion. Systems and subsystems exist in a hierarchical setting. A department is a subsystem of a corporation, for example, just as a corporation is a subsystem of an industry. In international relations states are considered subsystems, or components, of the entire international system. In analyzing the international system, researchers often posit distinct political, economic, cultural, and social subsystems.Although interactions between states have varied over time, by the latter decades of the 20th century they had become global in scope and unprecedented in their number and in the types of actors they involved. The volume, velocity, and types of interaction had expanded to include not only the greater movement of people but also trade, investment, ideas, and information—all of which were shaped by technology.

Structures, institutions, and levels of analysis: Since the 1970s the study of international relations has been marked by a renewed debate about the relationship between structures and institutions in international systems. On one side of the controversy was a revival of the school of realism, known as neorealism, which emerged with the publication of Kenneth Waltz's Theory of International Politics in 1979. Neorealism represented an effort to inject greater precision, or conceptual rigour, into realist theory. While retaining power as a central explanatory notion, Waltz's neorealism also incorporated the idea of structure as it is reflected in alliances and other cooperative arrangements among states of varying sizes, strengths, and capabilities. A bipolar system, for example, is a structure in which two states are dominant and the remaining states are allied with one or the other dominant state. According to Waltz and other neorealists, the structure of the international system limits the foreign-policy options available to states and influences international institutions in important ways. The United Nations (UN), for example, mirrors the structure of the existing international system insofar as it is dominated by leading powers such as the permanent members of the Security Council. Changes in international structure, including the rise of new powers, eventually lead to changes within international institutions. Thus, some neorealists have suggested that the Security Council's permanent membership will eventually be expanded to include countries such as Germany, India, Japan, and others.

Page 137

On the other side of the structures-institutions debate have been the neoliberal institutionalists, who contend that institutions matter beyond simply reflecting or codifying the power structure of the international system. Although neoliberal institutionalists accept the realist conception of states as the principal actors in a fundamentally anarchic environment, they argue that state behaviour can be modified by interaction with international institutions such as the European Union (EU), NATO, the World Trade Organization (WTO), and the UN. Such interaction, they contend, reduces the long-term potential for international conflict. Although neorealist structuralists and neoliberal institutionalists generally agree that international cooperation is possible, neorealists are much more skeptical of its chances for long-term success. According to neorealist logic, NATO should have dissolved in the 1990s after the collapse of the Soviet Union and the bipolar structure that had led to its formation. Instead, NATO was transformed in the decade following the end of the Cold War, taking on new tasks and responsibilities. This contradiction may be apparent, however, only because such adaptation can be viewed as reinforcing the neorealist thesis that institutions reflect the existing international structure: when that structure changes, they must change accordingly if they are to survive. Thus, NATO was able to survive because it underwent a transformation. At the same time, NATO's adaptation reflects the neoliberal-institutionalist contention that international organizations can modify national interests through the process of cooperation. Thus, NATO countries have altered their policies to take account of the needs of other members, and potential members have undergone rigorous internal reform in order to qualify for membership. Consequently, each theory appears to offer useful insights, and both together can form the basis of a unified approach to the relationship between structures and institutions.

Page 138

Central to neorealist structural theory is the levels-of-analysis question—i.e., the question of whether international inquiry should be focused at the individual, state, international-system, or other level. Introduced in the 1950s as part of an attempt to make research in international relations more scientific, the levels-of-analysis question provided a conceptual basis for addressing issues such as the effect of structure (bipolar or multipolar) on the behaviour of states or other units. At the same time, it offered a means of distinguishing between different sources of explanation and different objects of analysis. Thus, assuming that the international system shapes the options available to states as actors, it is plausible to suggest that the way in which decision makers respond to such options depends on how they perceive them and on the related opportunities and constraints created by domestic-level forces. In the 1980s this perspective was reflected in the burgeoning literature on "democratic peace theory," an approach that President Wilson undoubtedly had in mind when he called on Congress to support an effort "to make the world safe for democracy." Democratic peace theorists appealed to the internal characteristics of democratic states in order to explain why democracies tend not to fight each other. According to them, the peaceful norms that democratic states have developed for resolving differences with each other are an outgrowth of their domestic traditions of law and order, compromise, due process, protection of individual rights—including property rights and the right to freedom of speech—and an independent judiciary. In The Twenty Years' Crisis, 1919–1939: An Introduction to the Study of International Relations (1939), E.H. Carr contended that individuals' interest in the creation of a peaceful world could determine the foreign policies of democracies. A world constituted entirely of democracies, according to this view, would be peaceful.

By the late 1990s neorealist structuralist theory had been supplemented, in what was termed neoclassical realist theory, by explorations of the implications of structure, not just at the international-system level but also at the state level and within the state at the individual and group levels. Realist theory continued to be marked by major disagreements, however, a situation that supporters claimed was a reflection of rich intellectual resources and that detractors cited as an indication of fractured conceptual foundations. In any event, the contemporary effort to update, refine, and broaden realist theory, as well as the ongoing debate between neorealism and neoliberalism, may represent a trend toward a synthesis of the various realist schools of thought.

Recent perspectives, Constructivism: In the late 20th century the study of international relations was increasingly influenced by constructivism. According to this approach, the behaviour of humans is determined by their identity, which itself is shaped by society's values, history, practices, and institutions. Constructivists hold that all institutions, including the state, are socially constructed, in the sense that they reflect an "intersubjective consensus" of shared beliefs about political practice, acceptable social behaviour, and values. In much the same way, the individual members of the state or other unit continuously construct the reality about which policy decisions, including decisions about war and peace and conflict and cooperation, are made. Some constructivists contend that gender is socially constructed. On the basis of this thesis, feminist theories of international relations have attempted to address the fundamental question of the extent to which gender-based role differentiation is socially rather than biologically determined. In so doing, they have sought to answer questions such as: Are men more prone than women to aggressive, warlike behaviour? If gender roles are socially constructed, then according to feminist theory it would be possible to reduce male aggressiveness by changing beliefs or values regarding what it is to be male. On the other hand, if aggression is the product of male biology, then such change becomes impossible, or at least considerably more difficult. Part of the newer intellectual landscape in the study of international relations is formed by postmodernism and critical theory. According to postmodernism, the international structures posited in realist and other international relations theory are social constructions that reflect a worldview that serves the interests of elites. Critical theory was developed from the 1920s by the Frankfurt School of social and political philosophers, especially Jürgen Habermas and Herbert Marcuse (1898–1979). For critical theory the essential issue is how to emancipate human beings from social institutions and practices that oppress them. Although inspired by Marxism, critical theorists recognize forms of domination other than class domination, including those based on gender, race, religion, ethnicity, and nationalism. Because each of these forms has been in abundant evidence in the global landscape, critical theory was thought to provide important insights into the study of international relations at the start of the 21st century.

International political economy: Nothing is more illustrative of the inherently interdisciplinary nature of international relations inquiry than the nexus between economic and political factors. Although politics and economics have been studied separately for analytic purposes and as academic disciplines, and although each has its own paradigms, theories, and methodologies, it has long been recognized that economic factors shape political decisions, just as political factors may have a decisive influence on economic choices. Writings on political economy proliferated from the rise of the modern state in the mid-17th century until the mid-19th century. Much of the literature emphasized mercantilism, the notion that economic activity is, or should be, subservient to the interests of the state. Influenced by the work of Adam Smith (1723–90), David Ricardo (1772–1823), Richard Cobden (1804–65), and John Stuart Mill (1806–73), political economists of this period developed a fundamentally different approach, known as economic liberalism, that held that a system of free trade supported by government policies of laissez-faire would lead to economic growth and expanded trade and make an important contribution to international peace. In the latter 19th century a third approach, based on the writings of Karl Marx, argued that an increasingly poor proletariat and an increasingly affluent bourgeoisie would eventually clash in a violent revolution resulting in the overthrow of the latter, the destruction of capitalism, and the emergence of communism. Each of these sharply differing approaches has left its imprimatur on contemporary theories of international political economy. The earlier mercantilist approach influenced contemporary economic nationalism, which is characterized by several important assumptions: (1) states cannot remain powerful in an anarchic setting without a strong economy, (2) economic strength must be preserved by protecting key industries and jobs, (3) such protectionism may require tariffs and governmental subsidies, (4) low-priced imports may threaten domestic jobs and industry, (5) the state can and should remain sovereign in economic matters, and (6) membership in international economic organizations such as the WTO and agreements such as the North American Free Trade Agreement may have adverse consequences for national strength.

Page 141

Contemporary economic liberalism shares with classical liberalism the contention that the only way a state can maximize economic growth is by allowing markets to operate free from government intervention. They maintain that tariffs—which have the effect of distorting the allocation of resources, production, and trade—restrict economic growth and should be abolished. Accordingly, they support the creation and expansion of regional and international free-trade organizations. Citing Ricardo's theory of comparative advantage and earlier ideas of Smith, they also argue that national specialization is essential to world prosperity because it entails that countries will produce only those goods and services they are best equipped to make, which thus maximizes overall efficiency and minimizes overall costs. More generally, liberals maintain that the basic units of the global economy are now so closely integrated that efforts on the part of states to restrict trade with other countries are bound to fail. Debate between economic nationalists and liberals centres on the extent to which the state, even if it can do so, should halt or reverse the forces leading to economic globalization. The third basic contemporary approach to international political economy is rooted in Marxism, though the collapse of nearly all states with Marxist economies greatly undermined Marxist-inspired theories of international relations. Focusing on the relationship between wealthy states and impoverished ones, this approach, known as dependency theory, rejects the assumption that capitalism is the best means of economic development for impoverished states and instead argues that participation in international capitalism by poorer countries traps them in relationships of dependency and subordination to wealthier states.

Page 142

Scholarship and policy : study of international relations has always been heavily influenced by normative considerations. In the The Twenty Years' Crisis, Carr wrote that the "teleological aspect of the science of international politics has been conspicuous from the outset. It took its rise from a great and disastrous war; and the overwhelming purpose which dominated and inspired the pioneers of the new science was to obviate a recurrence of this disease of the international body politic." Indeed, in its early stages international relations theory was, according to Carr, "markedly and frankly utopian." As the field of international relations evolved during the tumultuous 20th century, the need to find nonviolent means of settling international disputes was a recurrent theme. This theme has been manifest in "world order thinking," which is usually traced to the approach to international relations espoused by President Wilson and set forth in his Fourteen Points for the post-World War I era. Proponents of world order thinking place major, if not primary, emphasis on building international organizations, strengthening international law, and fostering greater trust between countries. World order thinking, which gives primacy to international interest over national interest, addresses issues such as the possibility of just war; the distinction between wars of self-defense and wars of aggression; the elements of international justice, including equality of countries; the protection of human rights, including the legal and political justifications for international intervention in response to cases of internal ethnic cleansing and genocide; as well as issues related to global environmental problems resulting from population growth, urbanization, resource depletion, and pollution.

Page 142

The normative agenda of international relations emerges from the context of the times, the focus changing depending on an era's most pressing problems. The result is the identification of new topics that both shape international relations research and analysis and lead to a quest for innovative policies. At the beginning of the 21st century, research focused on issues such as terrorism, religious and ethnic conflict, the breakup of states, the emergence of substate and nonstate entities, the spread of weapons of mass destruction and efforts to counter nuclear proliferation, and the development of international institutions. The differences between the interests of scholars and those of practitioners of international affairs often have appeared to be more important than the similarities. Scholars, who often are committed to a world order fundamentally different from the existing one, usually have sought to avoid both the fact and the reputation of serving as apologists for official foreign policies. The principle of scientific detachment in social-science research also has contributed to the scholarly effort to evaluate international events and developments from a global perspective rather than from that of any one country's foreign policy. By contrast, practitioners have been more inclined to indifference than to hostility in their attitudes toward academics in international relations. They frequently have professed that they have found little in the field that is of value in their day-to-day work. There are few signs of direct influence in either direction, though there have been indirect and subtle exchanges that have been important in the conduct of foreign relations. New international programs or new directions in foreign policy undertaken by governments in open societies often have attracted much interest in universities, prompting the establishment of new research programs and even the development of new subfields of international studies.

Page 143

These subfields include "national development," which was stimulated by foreign-assistance programs to aid less-developed countries; area studies, which emerged after World War II from efforts by Western governments to acquire a deeper understanding of the Soviet Union and other countries; and national security studies, which resulted from the heavy influence on foreign policy of military factors, especially the threat of nuclear war in the Cold War period, the proliferation of weapons of mass destruction, ethnic and religious conflict, and international terrorism.

Page 144

The indirect influence of international relations studies on governmental thinking and policy making has been apparent in a number of noteworthy areas since the mid-20th century. The realist formulation of power politics, for example, has filtered into the foreign-policy thinking of the United States government to such an extent that foreign-policy decisions sometimes have been defended by arguments based on national interest and calculations of power, and opposing views have been dismissed as reflecting insufficient "hard-nosed" realism. In addition, U.S. foreign-policy decision making in times of crisis has been influenced by scholarly studies such as Graham Allison's Essence of Decision: Explaining the Cuban Missile Crisis (1971). During the Cold War, deterrence theories developed in the civilian sector, often by academic specialists, became the essential basis for strategic nuclear planning. The theoretical and operational aspects of deterrence received renewed attention from both scholars and policy makers as new actors and new weapons of mass destruction arose at the end of the 20th century. In the final decade of the 20th century, the U.S. government developed a national security strategy based on the assumption that the spread of free-market democracies would contribute to a more peaceful world. This strategy reflected interaction between the public-policy and academic communities, one aspect of which is (at least in Western democracies) the movement of scholars and practitioners between academia and government. The influence of academic democratic peace theory, for example, was reflected in the emphasis in U.S. foreign policy on democratization as a means of maintaining peace and world order.

Page 145

Whether the relationships between scholars and practitioners of international relations will be strengthened remains to be seen. Theories of international relations were notably deficient in their ability to predict the end of the Cold War. Moreover, the dramatic and accelerating changes that have transformed the world since the end of the 20th century have enhanced the problems inherent in developing accurate appraisals of the world in its international aspect. Nonetheless, there is a consensus that more sophisticated uses of quantitative, computer-assisted studies in universities, research organizations, and governments will aid researchers in their quest to better understand and explain the current state of the world and to produce more frequent and precise reports. The academic community, however, has generally lacked adequate resources and trained personnel to satisfy the growing demand for information. If the data on the conditions and relationships of the world's social systems—now made more manageable and more available for immediate use through computer systems and the Internet—are fully utilized, the academic field of international relations will have much more in common with governmental analysis and planning agencies than ever before. The end result could be the development of more innovative approaches to the formulation and conduct of foreign policy as well as to the broader study of international relations.
