Review Questions

• How does national defense function as a public good, and what implications does this have for government funding?
  • National defense operates as a public good because it is non-excludable and non-rivalrous; all citizens benefit from the protection it provides without diminishing its availability to others. This means that even those who do not directly contribute to military funding still receive its benefits. As a result, governments must allocate significant resources to ensure national defense, which can lead to challenges in balancing these expenditures with other public services.
• Evaluate the relationship between national defense spending and economic stability within a country.
  • National defense spending can have a complex relationship with economic stability. While high military expenditure can stimulate certain sectors of the economy through job creation in defense industries, it may also divert funds away from critical areas such as education and healthcare. Economically stable countries may find it easier to sustain robust national defense budgets without compromising social welfare programs, whereas countries facing economic hardship might struggle to maintain necessary levels of military readiness.
• Assess the impact of international alliances on a nation's approach to national defense and security policy.
  • International alliances significantly shape a nation's approach to national defense by enhancing collective security measures and enabling resource sharing among member states. These alliances allow countries to pool military capabilities, share intelligence, and coordinate strategies against common threats. The impact is profound; nations can bolster their defensive posture without bearing the full cost alone while fostering diplomatic relationships that can deter aggression and promote stability in their respective regions.
