The principle of realism asserts that international politics is fundamentally a struggle for power among self-interested states. Within an anarchic international system, states are ultimately dependent on their own capabilities, or power, to further their national interests and ensure their survival.
Understanding the Core Tenets of Realism
Realism is a foundational theory in international relations that emphasizes the competitive and conflictual side of international politics. It operates on several key assumptions:
1. State-Centrism
Realists view states as the primary and most important actors in international affairs. Other actors, such as international organizations or non-governmental organizations, are considered less significant.
2. Anarchy
The international system lacks a central authority or government above states. This absence of a global enforcer means there's no higher power to resolve disputes or enforce agreements, leading to a "self-help" system where states must rely on themselves.
3. Self-Interest and Survival
States are rational actors driven by their own national interests, with the ultimate goal being survival. All foreign policy decisions are viewed through the lens of how they contribute to the state's security and power.
4. Power
Power is the most crucial element in international politics. It is the means by which states ensure their security and advance their interests. Power can be military, economic, or even diplomatic.
5. Inevitability of Conflict
Due to the anarchic nature of the system and the inherent competition for power and security, realists often see conflict as an ever-present possibility, if not an inevitability.
Types of Realism
While sharing core principles, realism has evolved into different schools of thought:
Classical Realism
Originating with thinkers like Thucydides, Niccolò Machiavelli, and Hans Morgenthau, classical realism posits that the struggle for power is rooted in human nature. It suggests that individuals, and by extension states, have an innate desire for dominance.
Structural Realism (Neorealism)
Pioneered by Kenneth Waltz, structural realism shifts the focus from human nature to the anarchic structure of the international system itself. It argues that this structure compels states to prioritize power and security, regardless of their internal political systems or the nature of their leaders.
- Defensive Realism: States seek enough power to ensure their security but avoid maximizing it, as excessive power can provoke counter-balancing by other states.
- Offensive Realism: States seek to maximize their power and achieve hegemony because only by being the most powerful can a state guarantee its survival in an anarchic world.
Practical Implications and Examples
The principles of realism are often reflected in the foreign policy decisions of states.
- Military Build-up: Nations investing heavily in their armed forces to deter potential adversaries, such as the ongoing military competition among major global powers.
- Balance of Power Politics: States forming alliances to counter the rising power of another state or bloc, preventing any single entity from dominating the system. This can be seen in historical alliances like those leading up to World War I and II, or contemporary strategic partnerships.
- Emphasis on Sovereignty: Countries strongly asserting their national sovereignty and resisting external interference, reflecting the self-help nature of the international system.
- Geopolitical Competition: The rivalry between major powers for influence in key strategic regions, often involving economic, military, and diplomatic tools to secure advantages.
Realism vs. Other Theories
To further clarify realism, it's helpful to contrast it with other major theories in international relations:
| Feature | Realism | Liberalism | Constructivism |
|---|---|---|---|
| Key Actors | States | States, international organizations, NGOs, individuals | States, individuals, transnational networks |
| Core Motive | Power, Security, Survival | Cooperation, Democracy, Economic Interdependence | Ideas, Norms, Identity, Social Construction of Reality |
| International | Anarchic, Conflictual | Cooperative, Rule-bound, Potential for Peace | Shaped by shared understandings, evolving norms |
| View of Human | Selfish, Power-seeking | Rational, Capable of Cooperation | Socially constructed, influenced by culture and norms |
| Role of Law | Limited, serves state interest | Essential for order and cooperation | Shapes state identity and interests |
Realism provides a powerful lens through which to understand the often harsh realities of international politics, prioritizing national interest and the pursuit of power in a world without a global governing body.
