International Relations Theories: Realism, Liberalism, Constructivism

Constructivism in International Relations

Constructivism argues that international relations are socially constructed, shaped by ideas, norms, and interactions between actors like states, institutions, and individuals. Both agents (e.g., states) and structures (e.g., norms, institutions) mutually influence each other.

Key Ideas of Constructivism

1. Social Construction: What we consider natural or habitual is a result of socialization. Ideas and norms shape state behavior and international relations.

2. Agents and Structures: The international system comprises agents and structures, which are mutually constitutive. Agents create structures, and structures shape agents. Identities and preferences are socially constructed, not fixed.

3. Anarchy is What States Make of It: Anarchy (lack of central authority) in international relations is not inherently dangerous but shaped by states’ interactions and social contexts.

4. Logic of Appropriateness vs. Consequences

   • Logic of Consequences: States act based on cost-benefit calculations (e.g., liberalism).
   • Logic of Appropriateness: States act according to social norms and what is considered "appropriate" in their context.

5. Socialization and Cooperation: States can build trust and cooperate through shared norms, creating more stable international relations.

6. Domestic and International Causation: Domestic norms influence foreign policy, while international norms affect state behavior globally.

Advantages of Constructivism

• Helps explain the emergence of ideas like sovereignty, human rights, and foreign aid.
• Useful in understanding regional integration and leaders' decisions based on norms.

Limitations of Constructivism

• Does not fully explain how competition under anarchy might disappear.
• Struggles to explain how great powers act when national security is at stake.

Liberalism in International Relations

Liberalism in international relations emphasizes cooperation among states when the right political, economic, and institutional conditions are present. It is based on Enlightenment values and has an optimistic view of human nature, unlike realism.

Core Ideas of Liberalism

• Anarchy and Cooperation: While the international system is anarchic, cooperation and peace are possible with the right conditions.
• Rational Actors: States are rational and self-interested but can cooperate rather than fight.
• Beyond Power: Liberals consider domestic institutions, economic interdependence, and international organizations as important factors in cooperation.

Three Schools of Liberal Thought

1. Democratic Liberalism: Democracies do not go to war with each other (Democratic Peace Theory).
2. Commercial Liberalism: Economic interdependence fosters peace, as war harms mutual economic interests.
3. Liberal Institutionalism: International organizations encourage cooperation and resolve conflicts.

Key Concepts in Liberalism

• Democracy and Trade: Democracies tend to trade more, creating stability and reducing war risks.
• Interdependence: Economic ties and international institutions make war less appealing.
• International Organizations: Democracies support international institutions that promote peace and cooperation.

Challenges to Liberalism

• Economic Instability: Interdependence does not guarantee stability; economic crises can still lead to conflict.
• Democratic Peace: Evidence for democratic peace theory is inconclusive.
• EU Peace: The reason for peace within the EU is debated—whether it's due to institutions, interdependence, or power balance.

While liberalism promotes cooperation, it faces challenges in fully explaining long-term peace and stability in global politics.

Realism in International Relations

Realism is a key theory in international relations, emphasizing the role of power, security, and state survival in shaping global politics. Rooted in the idea that the international system is anarchic—there is no central authority above states—realism asserts that states act primarily out of self-interest to ensure their survival and maximize their power.

Key Concepts of Realism

1. Power: Realists believe that power is the central currency in international relations. States seek to enhance their military, economic, and political power to secure their position in the international system. Power is seen as relational, meaning it is always assessed in relation to other states.

2. Statism: States are the primary actors in international relations. Sovereignty, or supreme authority within a state's borders, is essential for survival. States compete for power in a zero-sum environment, where one state's gain is another’s loss.

3. Survival: The primary goal of any state is survival. Realists argue that states often make morally questionable decisions if they believe those actions are necessary for ensuring their security and continued existence.

4. Self-Help & Security Dilemma: Since there is no global authority to ensure security, states must rely on their own resources. This often leads to the security dilemma, where one state's efforts to increase security cause others to feel threatened, leading to an arms race.

Classical vs. Neorealism

• Classical Realism: Focuses on human nature as the driving force behind state behavior, suggesting that states seek power due to inherent human desires.
• Neorealism: Introduced by Kenneth Waltz, this theory emphasizes the structure of the international system and the distribution of power rather than human nature. States are seen as rational actors driven by the system's anarchic nature.

In summary, realism highlights the importance of power, state survival, and the challenges of an anarchic world system in shaping international relations.
