Defensive Realism

Definition

Defensive realism is a theory in international relations that suggests states are primarily motivated by the need to ensure their own security and maintain their sovereignty. This perspective posits that rather than seeking aggressive expansion, states prioritize defensive measures to protect themselves from potential threats, emphasizing a balance of power as a way to prevent conflict. It contrasts with offensive realism, which argues that states pursue aggressive policies to maximize their power and influence.

Review Questions

• How does defensive realism explain the behavior of states in the international system?
  • Defensive realism explains state behavior as primarily driven by the need for security and survival. States seek to protect their sovereignty and ensure their safety rather than engaging in aggressive expansion. This leads to strategies that emphasize maintaining a balance of power, avoiding unnecessary conflicts, and fostering diplomatic relations when beneficial for mutual security.
• Discuss how the concept of the security dilemma is relevant to defensive realism and its implications for international relations.
  • The security dilemma is central to defensive realism as it illustrates how efforts by one state to enhance its security can create insecurity for others. This dynamic can lead to an escalation of tensions, as states may respond defensively by increasing their military capabilities, potentially leading to conflict. Defensive realism advocates for understanding this dilemma to encourage cooperation and stability among states, thus reducing the likelihood of miscalculations that can lead to war.
• Evaluate the effectiveness of defensive realism in explaining contemporary international conflicts compared to offensive realism.
  • Evaluating defensive realism against offensive realism in contemporary international conflicts reveals insights into state behavior shaped by security needs rather than aggressive pursuits. Defensive realism often accounts for the cautious responses seen in regions like Europe, where states prioritize diplomatic engagements over expansionist policies. In contrast, offensive realism may provide explanations for more aggressive actions observed in some rising powers.
