IR Theories

INTERNATIONAL RELATIONS (IR) THEORIES — DETAILED STUDY NOTES

What is the Aim of IR Theories?

  • To provide frameworks for understanding agency, process, and structure in international relations.

  • Each theory seeks to explain how states behave, why conflicts or cooperation occur, and how the international system is organized.

  • United by the goal of explaining and predicting the behavior of actors (especially states) in the anarchic international system.

Context of the Development of Theories:

  • Realism: Emerged after WWI and WWII, as the catastrophic wars highlighted the importance of power, security, and survival in a world without overarching authority.

  • Liberalism: Grew after WWI, particularly influenced by Woodrow Wilson’s Fourteen Points and the creation of the League of Nations, promoting ideals of peace through democracy and international institutions.

  • Constructivism: Developed in the 1980s, gained prominence after the Cold War, questioning the materialist assumptions of Realism and Liberalism and emphasizing the social construction of international relations.

REALISM

What is Realism?

  • A dominant theory that views international politics as a struggle for power among self-interested states operating in an anarchic international system (i.e., no world government).

  • Core belief: Security and survival are the primary goals of all states.

Key Realist Scholars:

  • Hans Morgenthau (Classical Realism)

  • Kenneth Waltz (Neorealism/Structural Realism)

  • John Mearsheimer (Offensive Realism)

Core Concepts:

Anarchy

  • No central authority above states; every state must ensure its own survival.

  • Quote: "Because some states may at any time use force, all states must be prepared to do so" — Waltz, 1979, p. 102.

  • Anarchy leads to a self-help system — states rely on themselves, not others.

Important progression:

  • First Image: Bad individuals cause war.

  • Second Image: Bad states (e.g., dictatorships) cause war.

  • Third Image: The system itself (anarchy) inevitably leads to war — even good individuals and good states are trapped.

Security Dilemma

  • Actions taken by a state to enhance its security often threaten other states, prompting them to increase their security, leading to an arms race and increased instability.

  • Example: NATO expansion post-Cold War triggered Russian fears, leading to military modernization and invasions (Georgia 2008, Ukraine 2014 and 2022).

Power and Conflict

  • Mearsheimer: "The international system creates powerful incentives for states to look for opportunities to gain power at the expense of rivals."

  • Zero-Sum Game: One state's gain is another state's loss.

Example:

  • WWII: Nazi Germany’s territorial ambitions threatened others, leading to war.

Cooperation Possibility

  • Temporary, not genuine.

  • Balance of Power: Smaller states unite to counter a threatening larger state.

  • Cooperation arises only when it serves national interest or balances a threat.

Example:

  • Napoleonic Wars: Coalition against France to restore balance.

Limitations of Realism:

  • Deterministic: Views outcomes as inevitable.

  • Pessimistic: Sees conflict as unavoidable.

  • Neglects non-state actors: Focus solely on state-centric world.

Additional Quotes:

  • "Creating a peaceful world is surely an attractive idea, but it is not a practical one." — Mearsheimer (2001, p. 17)

LIBERALISM

What is Liberalism?

  • A theory that stresses the possibility of cooperation, democracy, and international institutions in reducing conflict.

  • Believes that although the system is anarchic, it is tameable through institutions, trade, and democracy.

Key Liberal Scholars:

  • Immanuel Kant (Perpetual Peace)

  • Robert Keohane (Neoliberal Institutionalism)

Core Concepts:

Anarchy

  • Accepts anarchy but believes it can be managed through institutions and shared interests.

Causes of Conflict (Keohane):

  1. Asymmetrical Information: Uncertainty causes mistrust.

  2. Moral Hazard: Incentives for reckless behavior if others bear the risk.

  3. Irresponsibility: States making promises they don't intend to keep.

Cooperation Possibility

  • International Institutions like the UN help states share information, reduce uncertainty, and encourage trust.

  • Interdependence: Economic ties make war costly and less attractive.

  • Democratic Peace Theory: Democracies rarely (if ever) fight one another.

Examples:

  • Climate change panels (COP27): Collective action on a global issue.

  • South Africa: Peacefully dismantled nuclear weapons post-apartheid.

Democratic Peace Theory

  • Democracies are less likely to go to war with each other due to shared norms, political transparency, and electoral accountability.

Key Scholar:

  • Michael Doyle: Explains why democracies inherently prefer peaceful dispute resolution.

Example:

  • Post-WWII Europe: Cooperation between former rivals like France and Germany through institutions like the EU.

Limitations of Liberalism:

  • Democracies do use force (e.g., US invasion of Panama 1989).

  • Non-democracies can also sustain peace.

  • May overestimate the ability of institutions to prevent war.

Additional Quotes:

  • "Liberals tend to be hopeful about the prospects of making the world safer and more peaceful." — Mearsheimer (2001, p. 15)

  • Keohane criticizes realism's fatalism: "We would be forced into the absurd position that disasters like WWI were somehow in the interests of empires."

CONSTRUCTIVISM

What is Constructivism?

  • A sociological approach emphasizing that the international system is socially constructed, not just materially determined.

  • Identities, norms, interactions, and collective meanings shape state behavior.

Key Constructivist Scholars:

  • Alexander Wendt ("Anarchy is what states make of it")

  • Peter Berger & Thomas Luckmann ("The Social Construction of Reality")

Core Concepts:

Anarchy

  • Not inevitable; depends on how states perceive and interact with each other.

  • "Anarchy is what states make of it" — Wendt.

Three possible anarchical systems:

  1. Competitive Security System: Hostile, zero-sum.

  2. Individualistic Security System: Pragmatic cooperation.

  3. Cooperative Security System: Collective identity and altruism.

Example:

  • Nuclear relations: USA views UK’s nuclear weapons as non-threatening (shared identity), but is wary of China and Russia (different identities).

Causes of Conflict

  • Conflicts arise from mismatched identities, norms, and social threats.

  • Threats are not objective; they are constructed through social interaction.

Examples:

  • Nazi Germany: Interaction with Treaty of Versailles and humiliation led to a predatory state.

  • North Korea: Isolation and threat perception created by socialized history.

Cooperation Possibility

  • Depends on changes in shared ideas and identities.

Example:

  • Gorbachev’s reforms: Anti-militarist stance born from personal convictions, not material constraints.

Limitations of Constructivism:

  • Lacks predictive power: Hard to make specific predictions.

  • Subjectivity: Relies on interpretations of ideas and norms.

Additional Quotes:

  • "It offers a framework for thinking about social interaction but makes no claims about specific outcomes." — Finnemore & Sikkink (2001, p. 393)

  • "Things like money, sovereignty, and rights exist because people believe they do." — Finnemore & Sikkink

EXTENDED QUESTIONS

How does avoiding Eurocentrism change IR?

  • Shifts the focus from Western experiences (colonialism, liberal democracy) to include perspectives from Africa, Asia, Latin America.

  • Acknowledges alternative systems like Ubuntu (African philosophy) or non-Western norms in diplomacy.

Which theory best explains challenges to the current international order?

  • Constructivism:

    • Russia’s annexation of Crimea based on national identity narratives.

    • China’s Belt and Road Initiative reflects historical "Middle Kingdom" identity.

Are norms or rational self-interest more important for rules and cooperation?

  • Realists: Rational self-interest (power).

  • Liberals: Rational self-interest but conditioned by institutions.

  • Constructivists: Norms shape rationality itself.

How would Realism and Constructivism explain the interwar period?

  • Realism: Power vacuum post-WWI led to aggressive expansion.

  • Constructivism: Humiliation of Germany socially constructed resentment, leading to WWII.

Do IR dynamics stay constant or change?

  • Realism: Constant (power struggle).

  • Liberalism: Changeable via institutions.

  • Constructivism: Changeable via social interactions and evolving norms.

Is international politics entirely anarchic?

  • Realists: Yes, permanently.

  • Liberals: Yes, but manageable.

  • Constructivists: No, it’s socially constructed and can be transformed.

What would it mean to decolonize international political theory?

  • Recognizing non-Western theories, histories, and practices as legitimate and critical to understanding global politics.

  • Moving beyond a Eurocentric framework.

Can we predict the future of international politics?

  • Realism: Predict general patterns (conflict, balancing).

  • Liberalism: Optimistic predictions of greater cooperation.

  • Constructivism: Cannot predict — future depends on evolving identities and norms.
