16. Still a Discipline After All These Debates?

This chapter considers how the arguments associated with the thirteen different theories of International Relations discussed in the book sum up. More specifically, it asks whether IR is (still?) a discipline, and whether it is likely to remain one. The chapter examines the intellectual and social patterns of IR and the discipline as a social system, along with its relations of power, privilege, and careers. It also reflects on where, what, and how IR is today by drawing on theories from the sociology of science, whether IR can be regarded as a subdiscipline within political science, and the social structure of IR. It argues that the discipline of international relations is likely to continue whether or not ‘international relations’ remains a distinct or delineable object. It also contends that the core of the intellectual structure in the discipline of IR has been recurring ‘great debates’.

9. Constructivism

This chapter examines the key debates that have shaped the development of constructivism in International Relations (IR). It first considers the idea that international relations is a social construction, as it emerged from the critique of more traditional theories of IR. It then explores the distinctions among various constructivisms, with particular emphasis on the contrast between those who seek a ‘better’ social science, and hence better theory, versus those who argue that constructivism is an approach that rests on assumptions at odds with those of positivist method. The chapter proceeds by discussing constructivists' critique of rationalism, along with constructivism as a ‘middle ground’ between rationalist and poststructuralist approaches to IR. It also analyses the role of language and causality in the debate between rationalists and constructivists. Finally, it links all these insights to the War on Terror.

13. Normative International Relations Theory

This chapter deals with normative international relations theory, a field of study that relies on a variety of approaches and theories to explore moral expectations, decisions, and dilemmas in world politics. Normative IR theory has adopted — and adapted — conceptual categories such as communitarianism and cosmopolitanism from political theory. It also borrows from moral philosophy to designate different types of ethical reasoning, such as deontology and consequentialism. The chapter begins with an overview of the history, influences, and some of the categories that normative IR theory brings to the study of international relations. It then examines the ways in which normative IR theory engages with the hidden ethical assumptions of a range of IR approaches. It also considers the case of civilian deaths during the 2003 Iraq war in relation to the the just war tradition, and more specifically to the idea that soldiers have duties to exercise restraint in war.

5. Neoliberalism

This chapter examines the neoliberalist argument that international institutions promote international cooperation. While neoliberalism acknowledges that cooperation can be difficult to achieve in anarchic conditions, it insists that institutions allow states to overcome a variety of collective action impediments. The central concern of neoliberal analysis is how institutions do so, and how they might be redesigned to more efficiently obtain cooperative outcomes. This chapter considers three questions that are relevant for understanding neoliberal contributions: How did neoliberalism emerge? What are the barriers to international cooperation? How does neoliberalism study international institutions. The chapter uses the World Trade Organization as a case study to illustrate the importance of institutional design for international free trade cooperation. Along the way, various concepts such as interdependence, hegemonic stability, hegemon, bargaining, defection, compliance, autonomy, and principal–agent theory are discussed, along with the game known as Prisoner's Dilemma.

3. Structural Realism

This chapter examines why states pursue power from the perspective of structural realism. It considers a body of realist theories that argue that states have deep concern for the balance of power and compete among themselves either to gain power at the expense of others, or at least to make sure they do not lose power. This competition for power makes for a dangerous world where states sometimes fight each other. There are, however, important differences among structural realists. The chapter first explains why states want power and how much power they want before discussing the causes of war. These theoretical issues are illuminated with a case study that assesses whether China can rise peacefully according to offensive realism vs. defensive realism. Along the way, concepts such as the security dilemma, offence–defence balance, central war, buck-passing, unipolarity, bipolarity, and multipolarity, and deterrence are analysed.

2. Classical Realism

This chapter examines the central assumptions of classical realism by analysing the texts of ancient and modern writers and contrasting their ideas with neorealism and other variants of modern realism. Classical realism represents an approach to international relations that dates back to Thucydides and his account of the Peloponnesian War. According to classical realists, power plays a major role in politics, but they also acknowledge its limitations and the ways it can be self-defeating. The chapter begins with a discussion of the position of classical realists regarding order and stability, focusing on the views of Thucydides and Hans J. Morgenthau with respect to the concepts of community, balance of power, and interest and justice. It then considers what classical realists think about change and transformation as well as the nature and purpose of theory. It concludes by commenting on the Iraq war in the context of classical realism.

15. International Relations Theory and Globalization

This chapter examines the existing debate on the extent and nature of globalization and its implications for contemporary International Relations theory. It first considers the stakes involved in the globalization debate for a range of core theoretical perspectives in IR. It shows how the literature on globalization has developed over time, revealing how the nature of the debate has changed, and illustrates this both theoretically and empirically with a case study of the impact of globalization on the development of the welfare state before and since the global financial crisis. It also considers the empirical case against the globalization thesis what a competition state is and how it might confer a competitive advantage upon a national economy in an era of globalization. The chapter suggests that the current level of interdependence within the international system, although considerable, is not easily reconciled with the stronger variants of the globalization thesis.

4. Liberalism

This chapter examines the expansion of three central phenomena associated with liberalism and its emphasis on the potentially peace-promoting effects of domestic and transnational institutions: the spread of democracy throughout most of the world; globalization; and the proliferation of intergovernmental organizations, especially those composed primarily of democratic governments. Each of these assumptions supports and extends the other in a powerful feedback system envisioned by Immanuel Kant. The chapter first considers four major changes in the world over the last century and particularly over recent decade before discussing the ‘epidemiology’ of international conflict. It then explores constraints on war from the perspective of realism vs. liberal institutionalism, whether democracies are peaceful in general, and how order is nurtured within anarchy. It also presents a case study of the European Union and concludes with some reflections on power, hegemony, and liberalism.

14. Green Theory

This chapter examines how environmental concerns have influenced International Relations theory. It first provides a brief overview of the ecological crisis and the emergence of green theorizing in the social sciences and humanities in general, along with the status and impact of environmental issues and green thinking in IR theory. It then investigates green theory's transnational turn and how it has become more global, while critical IR theory has become increasingly green. It also considers the different ways in which environmental issues have influenced the evolution of traditional IR theory. It concludes with a case study of climate change to illustrate the diversity of theoretical approaches, including the distinctiveness of green theories. The chapter shows that a preoccupation with environmental justice is what unites the international political economy and normative wings of green IR theory.

11. Poststructuralism

This chapter examines how and why poststructuralism engaged International Relations (IR) from the 1980s to today. It begins by analysing the interdisciplinary context of social and political theory from which poststructuralism emerged, along with the misconceptions evident in the reception of the poststructuralist approach among mainstream theorists. It then considers what the critical attitude of poststructuralism means for social and political inquiry and draws on the work of Michel Foucault to highlight the importance of discourse, identity, subjectivity, and power to the poststructuralist approach. It also discusses the methodological features employed by poststructuralists in their readings of, and interventions in, international politics. The chapter concludes with a case study of images of famines and other kinds of humanitarian crisis that illustrates the poststructural approach.
