Review Questions

• How does Kenneth Waltz's theory of structural realism explain state behavior within an anarchic international system?
  • Kenneth Waltz's theory of structural realism posits that in an anarchic international system, where no central authority exists, states act primarily out of self-interest to ensure their own survival. This self-help dynamic shapes state interactions, compelling them to prioritize military capabilities and strategic alliances. As states navigate this competitive environment, their behaviors are influenced more by the structure of the system than by individual leaders or domestic politics.
• Discuss the implications of Waltz's ideas for understanding ongoing interstate tensions between major powers.
  • Waltz's ideas suggest that ongoing interstate tensions, such as those between the U.S. and China, can be understood through the lens of structural realism. The anarchic nature of the international system compels these states to compete for power and security. As they perceive each other as potential threats, they may engage in balancing strategies or form alliances to counter perceived threats, ultimately leading to heightened tensions and conflict.
• Evaluate the strengths and weaknesses of Kenneth Waltz's contributions to international relations theory in light of contemporary global security challenges.
  • Kenneth Waltz's contributions to international relations theory offer significant insights into understanding global security challenges today. His emphasis on structural factors provides a framework for analyzing state behavior amidst rising multipolarity and complex interdependence. However, critics argue that his focus on systemic analysis overlooks important domestic influences and non-state actors shaping conflicts. Balancing his insights with other theories can enrich our understanding of current issues like terrorism and cyber threats, emphasizing the need for a multifaceted approach in contemporary security studies.
