The military conflict in the east of Ukraine is a result of division of the Ukrainian society depending on the cultural influence of the milieu that has existed and evolved throughout the history, that of divergences of the Kiev political elite and the geopolitical interests in this area shown by the West (the EU and NATO) on one part, and by the Russian Federation on the other part. The military conflict in the East of Ukraine has started with the protest of the Ukrainian society against the governing elite when the latter refused to sign the EU Association Agreement (November 2013), but it became a determining one in the decline of the American unipolarity at the international arena in prefiguration of the European security and demonstration of influence of the Russian Federation in the post-Soviet space. If initially the internal political crisis that Ukraine has faced may be interpreted as a reaction of the society towards shifting of the national interest from the West to the East of the policy promoted by the president that was in office at that time, Victor Ianukovici, consequently this conflict has transformed for the young Ukrainian state in that of defending the whole territorial integrity.
