Review Questions

• How does Kenneth Waltz's concept of structural realism differ from classical realism in explaining state behavior?
  • Kenneth Waltz's structural realism emphasizes the role of the international system's structure in shaping state behavior, contrasting with classical realism that focuses on human nature and individual leaders. Structural realism argues that it is the anarchic nature of the international system that forces states to prioritize their survival and security through balancing power. This approach highlights systemic factors over personal motivations, making it a more systematic and predictable way to analyze international interactions.
• Discuss how Waltz's theories contribute to our understanding of the balance of power in international relations.
  • Waltz’s theories assert that the balance of power is a natural outcome of an anarchic international system where states seek to maximize their security. According to Waltz, when one state gains power or capability, others will respond by either increasing their own capabilities or forming alliances, thereby maintaining stability within the system. This balancing behavior is crucial for understanding how states interact, as it explains why wars can break out when power is perceived as unbalanced and why states are motivated to form coalitions against common threats.
• Evaluate the implications of Kenneth Waltz's ideas on defensive realism for contemporary security policies among nation-states.
  • Kenneth Waltz's defensive realism suggests that states should focus on maintaining their security rather than aggressive expansion. This perspective has significant implications for contemporary security policies, as it encourages nations to adopt strategies that prioritize defense and stability over offensive military action. In a world where miscalculations can lead to conflict, understanding the necessity for restraint and careful diplomatic engagement is vital. This approach also supports arms control agreements and multilateral cooperation as means to foster security without escalating tensions.
