Realist theory

Definition

Realist theory is a major perspective in international relations that emphasizes the role of the state as the primary actor, focusing on national interest, power dynamics, and the inherent anarchic nature of the international system. This theory argues that states act in their self-interest, often prioritizing security and survival over morality or ideology, which leads to a competitive environment where conflicts are likely. Realists believe that international politics is driven by power struggles and that cooperation is often limited.

Review Questions

• How does realist theory explain the behavior of states in an anarchic international system?
  • Realist theory suggests that in an anarchic international system, states prioritize their own survival and security above all else. This self-help mentality drives them to accumulate power and resources to protect their national interests. Consequently, states are likely to engage in competitive behaviors, such as forming alliances or engaging in military confrontations to deter threats. The absence of a global authority means that each state must navigate conflicts independently, which often leads to tension and rivalries.
• In what ways does the concept of balance of power relate to realist theory's understanding of global governance?
  • The balance of power is central to realist theory as it reflects how states interact within an anarchic international system. Realists believe that maintaining a balance among powerful states prevents any single state from dominating others, thus ensuring stability. In terms of global governance, this concept suggests that cooperation among states is based on pragmatic calculations of power rather than shared values or norms. States may form temporary alliances or coalitions to counteract threats and maintain this balance, showcasing how realism views governance as a strategic maneuvering among competing interests.
• Evaluate the implications of realist theory for contemporary global issues such as climate change and terrorism.
  • Realist theory implies that contemporary global issues like climate change and terrorism are often viewed through the lens of national interest and power dynamics. For example, while climate change poses a universal threat, realists might argue that states prioritize immediate security concerns over collaborative environmental action due to perceived competition for resources. Similarly, counterterrorism strategies may focus on military responses rather than addressing underlying causes, as states seek to protect their sovereignty and interests first. This perspective raises questions about the effectiveness of global governance structures aimed at collective action when foundational assumptions about state behavior prioritize self-interest over global cooperation.
