By the promotion of religious freedoms and affirmation of indigenous, historically-developed multi-religious structure of the Serbian society, the Republic of Serbia is established as a modern, secular European state. Cooperation between the state and churches and religious communities, support given to interreligious dialogues and mutual cooperation between churches and religious communities weaken the motivation for the manifestation of religious fanaticism and extremism and encourage the process of harmonization of religious relations on the principles of tolerance, understanding, respect and mutual solidarity of churches and religious communities, which strengthens the social cohesion of the society, and thus the national security of the state. The policies of education, science, culture, technological development and environmental protection are an essential part of national security policy and significantly contribute to the achievement of its objectives. V. NATIONAL SECURITY SYSTEM The national security system is a normatively, structurally and functionally regulated set of elements whose activities help achieve the protection of national interests of the Republic of Serbia. 1. Structure of National Security System The national security system in a broader sense comprises the highest legislative, executive and judicial authorities: the National Assembly of the Republic of Serbia, the President of the Republic of Serbia, the National Security Council, Government, courts and prosecution offices. In the narrow sense, the national security system consists of: defense system, the Ministry of Interior forces, security-intelligence system and temporarily formed bodies and coordination bodies for some crisis. Defense system is a unique, structurally arranged set of forces and defense elements whose main goal is protection of the interests of the Republic of Serbia from the external armed threats. The Armed Forces of Serbia are the main part of the defense system. 32
