Slaughter (2011) International Relations, Principal Theories

A. Introduction

  • The study of international relations encompasses a variety of theoretical approaches:

    • Some theories are derived from international relations itself, while others are borrowed from disciplines like economics and sociology.

    • Few social scientific theories have not been applied to international relations.

    • Theories can be both internally and externally contested, leading to a pluralistic understanding.

    • Key schools of thought can be identified based on the variables they emphasize, such as military power, material interests, and ideological beliefs.

B. Realism

1. Overview

  • Realism (including structural Realism and Neorealism) posits that the international system is characterized by anarchy, meaning there is no central authority to govern states (Waltz).

  • States are seen as sovereign and autonomous, interacting only through coercion or mutual consent.

  • Importance of state power as the main variable for survival and defense.

2. Assumptions

  • Realists maintain four core assumptions (Mearsheimer 1994):

    1. Survival: The principal goal of every state is survival due to threats from foreign invasion.

    2. Rational Actors: States behave rationally to enhance their chances of survival.

    3. Military Capacity: All states hold military capability, leading to inherent uncertainty about others' intentions.

    4. Great Powers: The focus is on Great Powers that dominate international relations.

3. Variants of Realism

  • Offensive Realists: States strive to maximize their power (Mearsheimer 2001); hegemony is preferred.

  • Defensive Realists: Caution against dominance due to conflict risks; emphasize balance of power.

  • Polarity: Importance of the distribution of power among Great Powers in determining stability.

4. View on International Institutions

  • Realists regard international law and institutions skeptically, seeing them as reflections of power relations without constraining state behavior.

  • Laws are only enforced via state power and contingent on direct material interests.

C. Institutionalism

1. Overview

  • Institutionalism shares some realist assumptions but concludes that cooperation is feasible among nations.

  • Utilizes microeconomic theory and game theory to explain cooperation (Keohane 1984).

2. Mechanisms of Cooperation

  1. Extended Time Horizon: Iterative interactions encourage compliance over one-shot games.

  2. Increased Information: Institutions gather data about state behavior, reducing uncertainty and encouraging adherence to agreements.

  3. Efficiency: Institutions simplify negotiations and reduce transaction costs by providing structured forums.

3. Impact on International Law

  • Provides insights for international lawyers on designing effective institutions and understanding state behavior globally.

D. Liberalism

1. Overview

  • Liberalism presents a more diverse theoretical framework by emphasizing the influence of national characteristics.

  • Unlike Realism, liberals see differences among states as significant in their international relations.

2. Democratic Peace

  • Notable concept developed by Kant suggests that mature democracies rarely engage in war with one another (Doyle).

  • Questions remain on the causation behind this phenomenon and the risks associated with democratizing states.

3. Liberal Theory by Moravcsik

  • Proposes three core assumptions regarding international relations:

    1. Fundamental Actors: Individuals and private groups drive world politics, not just states.

    2. States as Representatives: States represent dominant domestic societal interests.

    3. State Behavior: State actions are influenced by the configuration of preferences within international systems.

4. Implications for International Law

  • Liberal theories challenge the traditional views of international law, emphasizing its impact on domestic politics and the design of international institutions.

E. Constructivism

1. Overview

  • Constructivism is an ontology focused on the significance of social meanings, contrasting with the rationalist theories.

2. Core Arguments

  • The importance of military power, trade, etc., lies in their social meanings rather than being objective facts about the world (Wendt 2000).

  • Identity and belief play significant roles; state interactions are influenced by perceptions and social context.

3. Norms and Behavior

  • Emphasizes the 'logic of appropriateness' over the 'logic of consequences', highlighting the impact of social norms on state behavior.

  • Recognizes the influence of non-state actors and institutions in shaping international relations.

F. The English School

  • Critiques rationalist theories and emphasizes social meanings and international society within world politics (Bull).

  • Focuses on historical context, domestic politics, and norms alongside the balance of power.

G. Critical Approaches

  • Diverse critiques of mainstream IR theories exist from Marxist, feminist, post-colonial, and ecological perspectives.

  • Emphasis on global class dynamics, gender in security frameworks, and human security rather than state-centric perspectives.

H. Conclusion

  • Various theories of international relations reflect different assumptions and serve unique analytic goals.

  • Each theory enables students to parse complex realities of international politics, avoiding a simplistic view of 'right' or 'wrong'.
