Final answer:
The United States must have a policy that upholds its military strength to maintain national security, while also considering economic interests and diversified threats.

Step-by-step explanation:
Key Aspects of U.S. National Security and Foreign Policy
To continue to exist as we know it today, the United States must have a policy that recognizes its military strength in the field of national security or foreign policy. This is illustrated by the fact that traditionally, military strength has been regarded as the core component of national security policies, with the U.S. maintaining a significant global military presence. However, national security now also encompasses economic security, energy security, environmental security, and the capacity to address threats from both state and non-state actors.
Economic interests are also integral to national security, especially in the context of international trade, multi-national agreements, and mutual inter-dependence. A country's economic health is crucial for its foreign policy influence and its ability to sustain a military force capable of global deployment. The goals of U.S. foreign policy notably include keeping the country safe, securing access to foreign markets, and protecting human rights.
Overall, the United States employs a grand strategy that utilizes diplomatic, economic, and military resources to advance its national interests. This comprehensive approach requires balancing different facets of power and influence to maintain the nation's security and prosperity, both at home and abroad.
