1. A national security policy is a framework that outlines how a country will provide security for the state and citizens. It addresses the country's role internationally, perceived threats domestically and abroad, and responsibilities of security agencies. 2. National security policies vary by country but generally outline core national interests, guidelines for addressing current and future threats and opportunities, and the roles of implementing actors. Some countries have a single unified document while others use defense policies or white papers. 3. National security policies are important for comprehensively addressing all threats, guiding implementation, increasing effectiveness of security agencies, building domestic consensus, and enhancing international cooperation and confidence. They must consider international law and broadly analyze a wide range of potential threats.
