Intelligence and National Security

Intelligence is essential for maintaining national security, as it allows governments and intelligence services to gather information about potential threats and respond accordingly. Military intelligence, in particular, plays a vital role in safeguarding national security by monitoring enemy activities and providing timely information to decision-makers. However, intelligence gathering must be conducted covertly to avoid alerting the target, and confidentiality is crucial to its success.
