Theoretical and conceptual approaches to the role of national and regional security on ensuring stability in Eastern Europe

Abstract

Events in Europe in the last decades of the twentieth century (the fall of the Berlin Wall, the unification of Germany, the abolition of the Warsaw Pact, the collapse of the communist bloc and the USSR) led to a reconsideration of Eastern European security. After the abolition of the Warsaw Pact, the ,,balance of power" strategy in achieving security no longer works and, as such, the Eastern European security system must be rebuilt in accordance with the new realities. The tendencies regarding the reorganization of the European security system are diverse and contradictory, each actor (state, group of states, organization) wanting to occupy a more advantageous place in order to be able to promote and, if necessary, to defend its own interests. This article aims to determine the main definitions and theories of national and regional security in the context of Eastern European stability. Also the authors are willing to identify some problems and trends in the region and to list the main actors who are responsible for dealing with challenging issues and how to avoid them.
