Detailed Study Notes on Realism, Power, International System, and Alliances in International Relations

2.1 Realism

Definition of Realism in International Relations (IR)

• Realism is a theoretical framework that holds a central position in the study of IR and focuses on power politics.

• No single theory can fully explain the complex range of international interactions, yet realism remains a significant perspective because of its historical significance.

Assumptions of Realism

• Historically contested by other perspectives (like idealism), realism emphasizes the role of power in international relations.

• Realists view human nature as essentially selfish.

• The primary actors in realism are states, as opposed to individuals or non-state actors.

• Realists see state behavior as driven by a rational pursuit of self-interest within an anarchic international system characterized by lack of a central authority.

Contrast with Idealism

• Idealism focuses on international law, morality, and organizations, believing that human nature is inherently good.

• Idealists are seen as holding unrealistic views of global relations and policies that place hope in cooperation and collective security efforts (e.g., the League of Nations).

• Example: U.S. President Woodrow Wilson's advocacy for the League of Nations post-World War I, which failed largely due to the rise of aggressor states in the 1930s.

Historical Context of Realism

• Post-World War I, realists criticized idealism for failing to recognize the harsh realities of power politics.

• Notable historical figures influencing realist thought:

  • Sun Tzu: Ancient strategist who advised rulers to prioritize survival using power rather than moral reasoning.

  • Thucydides: Chronicled the Peloponnesian War, emphasizing the notion that "the strong do what they can, and the weak accept what they must."

  • Niccolò Machiavelli: Advocated for pragmatic, sometimes deceitful governance to maintain power. The term "Machiavellian" derives from his name, indicating cunning political maneuvers.

  • Thomas Hobbes: Discussed the "state of nature," advocating for a strong authority to maintain peace and order among self-interested individuals.

• Hans Morgenthau popularized the idea that international politics is governed by objective laws rooted in national interests defined through power rather than morality.

Application in Policy

• Realism underpinned the U.S. strategy of containment during the Cold War, emphasizing that appeasement of aggressors leads to wider conflicts (e.g., Munich Agreement).

• Realists do not always advocate for military action but recognize when it becomes necessary, often opposing interventions when they risk national interests.

Principles of Dominance

• The foundation of realism is the principle of dominance in IR, meaning power is the central tenet driving state behavior.

• Realists view ideologies, religions, and cultural aspects as secondary to power politics. For them, states are similar in their pursuit of national power regardless of their ideological or cultural differences.

2.2 Power

Defining Power in IR

• Definition of Power: The ability to influence another actor to do something they would not otherwise do.

• Power is often synonymous with influence, where an actor's effectiveness is contingent upon their capability to affect the actions of others.

Issues with Defining Power

• Challenges in defining what a second actor might have done without the influence of the first actor lead to potential circular logic in measuring power.

Types of Power

1. Power as Influence

• Military force and economic sanctions are primary means to exert influence in IR.

• Example: The EU and the U.S. applied sanctions against Russia regarding its actions toward Ukraine.

2. Power as Capability

• Power also involves tangible metrics like:

  • Population

  • GDP (Gross Domestic Product)

  • Military capability

  • Territory

• USD GDP is often seen as the most indicative measure of a country's power but varies based on how it is calculated.

Non-material Elements of Power

• Long-term political culture, legitimacy, and diplomatic skill can enhance a state's power if effectively mobilized.

• Soft Power: Attributed to a state's ability to influence others by co-opting rather than coercing; includes cultural and ideological appeal.

• Example of Soft Power: U.S. promotion of free markets that resonated globally.

Relative Power

• Importance of relative power as states interact based on how their capabilities measure against their rivals.

• Example: India's increasing military capability relative to China, indicating India’s potential vulnerability in case of China expanding faster militarily.

Estimating Power in Wars

• Estimation often involves assessing relative military capabilities and popular support for government decisions:

  • Example: NATO versus Libyan forces during the 2011 intervention.

  • NATO had a likely 300:1 GDP advantage in resources over Libyan forces.

Elements of Power in IR

Long-term Power Resources

• GDP, population, territorial control, political culture, and the nation's reputation affect long-term stability.

Military Presence

• Military forces are crucial in the short term, evidenced by deployment capabilities and technological advantage.

Economic Factors

• Allocation of resources towards military versus other areas (e.g. social services) shows trade-offs in policy.

• Example: Balancing military expenditure with foreign aid initiatives post-9/11.

Geopolitics and International Relations

• Geography impacts power dynamics and strategic capabilities. Control over regions’ resources significantly influences states’ abilities to exert influence (e.g., oil pipelines).

2.3 The International System

Anarchy and Sovereignty

• Anarchy in IR means the absence of a central authority to enforce rules among sovereign nations.

• Sovereignty grants states full autonomy within its territory while ideally respecting other states’ sovereignty.

Collective Goods Problems

• Collective goods problems arise from the anarchic structure and lack of enforceable norms, making cooperation difficult in IR based on self-help principles.

Norms in the International System

• Majority of interactions in the international system adhere to established norms and expectations for behavior despite the underlying anarchy.

• Example: Despite anarchy, norms around diplomacy and sovereignty guide actions (e.g., non-interference policies).

Table of Norms and Sovereignty

Security Dilemma and Balance of Power

• The security dilemma occurs when states enhance their security (military power) but cause threats to others, prompting arms races.

• Balance of power defines the dynamics of interactions among state powers acting to keep stability and prevent dominance by any single actor.

2.4 Alliances

Purpose and Nature of Alliances

• Alliances are cooperatives of states acting together for common threats/results to enhance power.

• Examples: NATO formed in response to perceived Soviet threats, emphasizing collective security.

• Alliances based on vital national interests, often fluid and tactical (i.e., not eternal).

Challenges of Alliances

• Divided responses and responsibilities among members to manage costs (burden-sharing principles).

• Example: NATO members such as Greece and Turkey have formal alliances but hostile relations.
