National security refers to the protection of a nation's citizens, sovereignty, and territorial integrity from external threats. This concept encompasses various aspects, including military readiness, intelligence operations, and diplomatic efforts. National security is often a political priority as it directly affects a country's stability, economic prosperity, and global standing. Policymakers prioritize security measures to address potential risks, presenting strategic frameworks to mitigate threats, which can, in turn, influence public perceptions and shape political agendas.
