Defensive realism

Definition

Defensive realism is a theory in international relations that emphasizes the idea that states prioritize their security and survival over aggressive expansion. It argues that states are rational actors that seek to maintain their power and avoid conflict by focusing on defensive strategies. This perspective suggests that states are more likely to engage in self-help and form alliances to deter threats, which ties into broader discussions of military policy and national security.

Review Questions

• How does defensive realism explain the behavior of states in the context of national security?
  • Defensive realism explains that states behave in ways primarily focused on ensuring their security and survival rather than pursuing aggressive expansion. It suggests that rational state actors will adopt defensive strategies, including forming alliances and building military capabilities, to deter potential threats. This approach allows states to manage risks effectively while minimizing the chances of conflict.
• In what ways can the principles of defensive realism be observed in Japan's post-World War II pacifist policies under Article 9?
  • Japan's post-World War II pacifist policies under Article 9 reflect defensive realism by emphasizing self-defense rather than military aggression. Article 9 renounces war as a means of settling international disputes and limits Japan's military capabilities. This aligns with defensive realism as Japan focuses on maintaining security through alliances, particularly with the United States, while ensuring it does not provoke regional tensions.

  • The concept of defensive realism interacts with contemporary geopolitical tensions by highlighting how states react to perceived threats in their environment. In Japan's case, rising regional tensions, especially regarding North Korea and China's military assertiveness, compel Japan to rethink its pacifist stance while still adhering to its defensive principles. As Japan seeks to bolster its Self-Defense Forces and enhance security partnerships, it reflects defensive realism's core idea that states prioritize security while navigating complex international dynamics without becoming offensive aggressors.
