Review Questions

• How does national security influence a country's foreign policy decisions?
  • National security plays a crucial role in shaping a country's foreign policy by determining how it interacts with other nations. When faced with perceived threats, a government may adopt aggressive strategies, such as military intervention or forming alliances to bolster defenses. Conversely, if national security is viewed as stable, a nation might focus on diplomacy or economic partnerships instead. The balance between these approaches often reflects the prevailing views on national security within both the government and the public.
• Discuss the relationship between Congress's war powers and national security concerns.
  • Congress's war powers are fundamentally linked to national security as they allow for legislative oversight over military actions. The Constitution grants Congress the authority to declare war, which serves as a check on the executive branch's ability to engage in military conflicts. This relationship ensures that decisions impacting national security are debated and scrutinized at multiple levels. When Congress acts or refrains from acting on military matters, it directly influences how effectively the country can respond to security challenges.
• Evaluate how changes in global threats have affected the concept of national security in recent decades.
  • In recent decades, the concept of national security has evolved significantly due to changes in global threats. Traditional military threats have been joined by non-traditional challenges such as cyber attacks, terrorism, and climate change. This shift has led policymakers to rethink strategies and adopt more comprehensive approaches that include intelligence sharing, cyber defense initiatives, and international cooperation. As these new dimensions of threat emerge, the definitions and priorities surrounding national security continue to adapt in response to an increasingly complex global landscape.
