At an interval of approximately 25 years after the end of Cold War and the collapse of the Soviet Union, the Russian Federation tried to re-establish its hegemony in the Post So¬viet spaces. Since 2000, the Russian policy has become offensive for reinstating the status of power in its near neighbourhood as a Russian sphere of influence. The new forms of govern¬ment from the Community of Independent States (CSI) in particular those from Republic of Mol¬dova, Georgia, Ukraine represent a threat to its security as well as an obstacle to its hegemonic tendencies. In this way many researchers consider that Putin’s leadership is like a geostrategic” revenge of Moscow” on international arena, whose aim is to restore Russian influence in the world. As a result of Ukrainian crisis, in the specialized literature, and also in politicians’ spee¬ches, polemologists and scientists more and more the concept of hybrid war is used. This article emphasizes the main approaches and features of the phenomenon ”hybrid war”. Also, the author subjects to analysis hybrid threats to international security as well as state.
