National Security can be considered as a subset of which of the following?

National Security encompasses the protection and defense of a nation's sovereignty, territory, and citizens from external threats, and it often includes policies and measures to ensure the welfare and safety of its population. Within this framework, Homeland Security specifically focuses on protecting the United States from domestic threats and preventing terrorist attacks, while also responding to natural disasters and other emergencies. This makes Homeland Security a crucial component of National Security, as it addresses the internal dimensions of security that directly affect the nation’s overall stability and safety.

The relationship between National Security and Homeland Security is significant, as efforts in Homeland Security contribute to the broader objectives of National Security by preparing for, responding to, and recovering from incidents that could threaten the nation. Understanding this relationship is vital for comprehending how various sectors and strategies within security policies interact and support one another to maintain a secure homeland.
