Defensive Realism

Definition

Defensive realism is a theory in international relations that suggests states are primarily motivated by the need to maintain their security rather than seeking aggressive expansion. It emphasizes that the international system is anarchic, leading states to prioritize survival and stability over domination, often resulting in cautious behavior in the pursuit of power. This perspective contrasts with offensive realism, which posits that states are inherently aggressive and seek to maximize their power.

Review Questions

• How does defensive realism explain state behavior in an anarchic international system?
  • Defensive realism explains that in an anarchic international system, states prioritize their security and survival over aggressive expansion. This leads them to adopt cautious behaviors and strategies aimed at maintaining their position without provoking conflict. The emphasis is on defensive measures rather than offensive strategies, as states seek stability while navigating potential threats from others.
• What distinguishes defensive realism from offensive realism in terms of state motivations and strategies?
  • Defensive realism focuses on the idea that states are motivated primarily by the need for security and survival, advocating for cautious behavior. In contrast, offensive realism posits that states are inherently aggressive and seek to maximize their power through expansion. This fundamental difference shapes how each theory interprets international relations and state interactions, influencing strategies and responses to perceived threats.
• Evaluate the implications of defensive realism for understanding contemporary conflicts and international relations.
  • Defensive realism has significant implications for understanding contemporary conflicts, particularly in how states perceive each other's military capabilities and intentions. Misunderstandings stemming from the security dilemma can lead to escalations even when one state acts defensively. By analyzing conflicts through the lens of defensive realism, we can see how states may inadvertently provoke insecurity in others, prompting arms races or regional tensions that could have been avoided with better communication and trust-building measures.
