Nord Stream 2 as a Threat to National Interests of Poland and Ukraine

The article analyses Nord Stream 2 project in terms of the national interests of Poland and Ukraine. The authors carry out comparative analysis of risks and threats which are posed by the project to the national interests of both countries in economic, political and geopolitical spheres. The probable consequences of implementation of the Russian gas initiative are discussed. Scenarios of tactical and strategic steps of Poland and Ukraine are described. These steps would allow the countries to influence the process of Nord Stream 2 project implementation and, potentially, block it; as well as allow preparing their own energy systems to new conditions which might be formed after the launch of two lines of a new Russian gas pipeline in the Baltic Sea
