Liberalism in international relations: beyond anarchy to cooperation (UPSC PSIR Deep Dive)

Liberalism in International Relations: A World of Hope or Illusion?

Imagine a bustling global marketplace. Realists would see a chaotic arena where powerful vendors constantly jostle for dominance, ready to overturn a rival’s stall to gain an edge. In contrast, Liberals see the same marketplace but focus on the intricate web of shared rules, the mutually beneficial trade, and the community council (international institutions) that resolves disputes. This is the essence of Liberalism in International Relations—a paradigm built on the optimistic belief in human reason and the capacity for progress, suggesting that cooperation, not conflict, can define the global landscape.

While Realism paints a grim picture of perpetual power politics, Liberal Internationalism argues that states can create a more orderly and peaceful world. It is not a pacifist utopia; liberals acknowledge the necessity of self-defense. However, they contend that the anarchic nature of the international system can be mitigated through a powerful trifecta: international institutions, economic interdependence, and the spread of democracy.

The Liberal Path to Peace: The Kantian Triangle

Inspired by Immanuel Kant’s essay “Perpetual Peace,” liberal thought rests on three core pillars that are believed to create a virtuous cycle of peace and cooperation.

1. Democratic Peace Theory: This is a cornerstone of liberal thought. The core argument is simple yet profound: established democracies do not fight wars against one another. The reasoning is that in a democracy, where leaders are accountable to the people who bear the costs of war, the public’s inherent aversion to conflict acts as a powerful brake on aggression. Furthermore, democratic cultures favor negotiation and compromise over violence.

   Statistic: While the core tenet of the Democratic Peace Theory is a subject of academic debate, the global trend of democratization itself faces headwinds. According to International IDEA’s 2024 ‘Global State of Democracy’ report, declines in the quality of democracy now outnumber advances, with four in nine countries worse off in 2023 than in 2018.

2. Economic Interdependence / Commercial Liberalism: Following the ideas of Adam Smith, liberals argue that free trade fosters peace. When nations are economically intertwined, the costs of war become prohibitively high. Why attack a valuable trading partner or disrupt supply chains that are crucial to your own prosperity? This creates a “harmony of interests” where mutual economic benefits outweigh the potential gains from conflict.

3. International Institutions (Liberal Institutionalism): Liberals believe that institutions like the United Nations (UN), World Trade Organization (WTO), and the European Union (EU) are vital. They act as neutral forums for resolving disputes, creating and enforcing international law, fostering trust through repeated interaction, and providing a framework for Collective Security. The idea of collective security, first attempted with the League of Nations, is that an attack on one member state is considered an attack on all, creating a united front to deter aggressors.

Mnemonic for the Liberal Path to Peace: To easily recall these three pillars, remember “D.I.T.”

• Democracy (Democratic Peace)
• Institutions (Collective Security)
• Trade (Economic Interdependence)

The Liberal View of the State: Pluralism and Civil Society

Unlike Realists who see the state as a unitary, power-seeking actor, Liberals see it as a more complex entity. They agree that the state is sovereign but argue that it is not the only important actor on the world stage.

• The State as a Neutral Arbiter: Within a liberal-democratic country, the state is seen as a neutral framework of laws and institutions designed to mediate between competing interests in society. Its primary role is to protect citizens and allow them to pursue their interests freely, so long as they do not harm others.
• Pluralism: This core concept denotes a diffusion of power. Liberals argue that power is not concentrated solely in the central government. Instead, it is distributed among various groups, including political parties, interest groups, and corporations. This creates a system of checks and balances.
• Civil Society: Liberals make a clear distinction between the state (government, military, police) and civil society. Civil society comprises the vast array of non-governmental organizations (NGOs), social movements, trade unions, and cultural groups that people form voluntarily. Actors like Amnesty International, Greenpeace, or even multinational corporations (MNCs) can influence international relations, sometimes more effectively than states.

Analogy: Complex Interdependence is like a finely woven tapestry. In the past (a Realist world), the threads were thick and ran only between national governments. Today, the tapestry is incredibly dense, with countless threads of trade, finance, tourism, and communication connecting not just governments, but also companies, NGOs, and individuals across borders. Pulling one thread—like a trade dispute or a pandemic—can unravel distant parts of the fabric in unexpected ways.

The Liberal Order Under Stress: 21st-Century Realities

The post-Cold War era was seen as a triumph for Liberal Internationalism. However, recent events have mounted a severe challenge to its core tenets.

The 2022 Russian invasion of Ukraine serves as a stark case study. It directly challenges all three pillars of the liberal peace: a non-democracy attacking a democracy, the failure of economic ties to prevent war, and the paralysis of the UN Security Council in enforcing collective security.

1. The Limits of Collective Security: The war has exposed the critical weakness of the UN Security Council, where Russia’s veto power has rendered the body incapable of taking decisive action against its own aggression. This has severely weakened the international collective security system, leading to a humanitarian catastrophe.

2. The Weaponization of Interdependence: The liberal belief that economic ties foster peace has been turned on its head. In recent years, interdependence has been actively “weaponized.” Russia attempted to use its energy supplies to coerce Europe, while Western nations, in turn, have imposed unprecedented economic sanctions and cut Russia off from global financial systems like SWIFT. Similarly, concerns are rising over China’s control of critical minerals and its use of trade as a tool for political leverage. This trend suggests that interdependence can create vulnerabilities that lead to conflict, not just cooperation.

3. Democratic Recession: The global spread of democracy has stalled and, in many places, reversed. The rise of authoritarianism and populism within Western democracies themselves has weakened the coalition of states that have historically championed the liberal order.

Fun Fact: The predecessor to the United Nations, the League of Nations, had no army of its own and required unanimous votes for major decisions. Its inability to stop aggression in the 1930s was a key lesson that influenced the creation of the UN Charter and the Security Council, although the veto power remains a critical point of contention.

Critical Policy Appraisal

Analytical Lens: UPSC Focus (Mains & Prelims)

Conceptual Basis:

The philosophical bedrock of the Liberal approach is Immanuel Kant’s 1795 essay, “Perpetual Peace.” He outlined three “definitive articles” for achieving lasting peace: states must have a republican (democratic) constitution, there must be a federation of free states (international institutions), and cosmopolitan law should be limited to universal hospitality (trade and interaction). The modern legal manifestation is the UN Charter (1945), which establishes the principles of state sovereignty, collective security, and international cooperation.

UPSC Integration: Connecting the Dots:

• GS Paper 2 (Polity & International Relations): This topic is central to understanding the architecture of global governance—the roles of the UN, WTO, EU, and other regional bodies. It connects directly to India’s foreign policy of ‘strategic autonomy’ versus engagement with the liberal order.
• GS Paper 3 (Economy): The concept of economic interdependence is the theoretical foundation for globalization. It links to discussions on the WTO’s role, trade disputes, global supply chain resilience, and the impact of sanctions on the Indian and global economies.
• GS Paper 4 (Ethics): Liberalism’s emphasis on human rights, justice, and moral principles connects to ethical concepts like cosmopolitanism and the debate on humanitarian intervention (‘Responsibility to Protect’).

Future Impact & Policy Relevance:

The liberal international order is at a crossroads. The unipolar moment has ended, and a multipolar world is emerging with competing ideologies. The key question for policymakers is whether the core principles of liberalism—multilateralism, rule of law, and open trade—can be adapted to this new reality. The future may lie not in a single, US-led order, but in a more fragmented “multiplex world” where liberal institutions must coexist and compete with other models of governance. For India, this presents both challenges and opportunities to shape a new, more inclusive global order.

Prelims Practice Question (MCQ):

Which of the following concepts is NOT considered a core pillar of the Kantian Triangle, which underpins the Democratic Peace Theory?

a) The spread of democratic (republican) forms of government. b) The establishment of a balance of power between rival states. c) The growth of economic interdependence and international trade. d) The creation of international institutions to mediate disputes.

Answer and Explanation:

Correct Answer: (b) The Kantian Triangle, or the liberal theory of peace, is based on a virtuous cycle between Democracy, International Institutions, and Economic Interdependence. The concept of ‘balance of power’ is a central tenet of the Realist school of thought, which sees international relations as a struggle for power between states, not a quest for cooperation.

Mains Sample Question (15 Marks):

“The post-Cold War liberal international order is facing an unprecedented crisis, tested by geopolitical rivalries and the weaponization of interdependence. Critically analyze the contemporary relevance of liberal theories in explaining and navigating 21st-century global challenges, with special reference to the Russia-Ukraine conflict.”
