The world is facing the challenges imposed by a gross violation of the UN Charter and universally accepted norms of international law, especially the interference in the internal affairs of sovereign states, as well as concept and practice of preventive attacks and military interventionism. Attempts to give legitimacy to the creation of new states in the territories of sovereign states, members of the UN, violate the existing international legal order and significantly jeopardize the overall security situation in the world. Political, economic, cultural and military-security relations in the world are increasingly taking place in the global multipolar and multilateral environment in which a complex interdependence of states is increasingly being manifested. Transnational and asymmetric character of contemporary security challenges, risks and threats have influenced the fact that security is indivisible, and it is obvious that no country is able to independently solve complex problems of preserving and strengthening national security. Therefore, security in modern conditions is considered on a more global level, and national security is increasingly associated with the security situation in the closer and more remote environment. The answer to transnational asymmetric threats is in the integration of the national security systems, strengthening of multilateral security forums and the collective system of international security as key factors in securing peace, stability and democratic development of countries of the modern world. In such circumstances, there is a stronger need for a cooperative approach to maintaining and improving security based on cooperation and pooling of national security capacities of the states. Progress achieved in implementing the EU Common Foreign and Security Policy and the inclusion of European defense forces in resolving the security problems indicate an important role of the EU in the harmonization of relations and interests of European countries and taking a part of the joint responsibility in creating the European and global security. 5
