Political System and National Security according to D. Easton, G. Almond, and T. Parsons

Society and nature are systemic phenomena. In this respect, national security is a political system. It was best described by David Easton, Gabriel Almond, and Talcott Parsons, who specified its functional and structural components, as well as its methodological significance. This article introduces the main functions of the modern political system and national security based on the philosophical and psychological concept of activity. It offers an authentic structural and functional model of the political system that provides the national security. The functional components can be gnostic, design, constructive, communicative, or organizational. The structural components of the system include: 1) objectives and principles, 2) material, financial, and intellectual resources of the state and society, 3) national bodies, forces, and tools designed for security tasks, 4) non-governmental organizations, bodies, and institutions that assist the state in security tasks, 5) security facilities (individuals, society, and the state), 6) security environment (challenges, dangers, and threats to security facilities).
