Review Questions

• How does national defense function as a public good, and what implications does this have for funding and resource allocation?
  • National defense functions as a public good because it is available to all citizens regardless of their individual contribution to its funding. This means that everyone benefits from the protection it provides, creating a scenario where free-riding can occur; individuals may avoid paying taxes while still receiving security benefits. Consequently, governments must allocate substantial resources through taxation to ensure adequate military readiness and infrastructure for national defense.
• Analyze the relationship between national defense and international relations in the context of collective security arrangements.
  • National defense is closely linked to international relations through collective security arrangements like NATO, which emphasize mutual cooperation among nations for protection against common threats. Such agreements enhance a nation's defense posture by pooling resources and sharing intelligence, ultimately deterring potential aggressors. The interconnectedness created by these alliances reflects how national defense strategies can shape diplomatic relations and global stability.
• Evaluate how evolving threats, such as cyber warfare and terrorism, impact traditional notions of national defense and policy-making.
  • Evolving threats like cyber warfare and terrorism challenge traditional notions of national defense that primarily focus on military strength against state actors. Policymakers must adapt their strategies to address these non-conventional risks, requiring investments in cybersecurity and intelligence operations. This shift influences national defense policies by broadening the scope of security measures and emphasizing collaboration with private sectors and international partners to combat these modern challenges effectively.
