The Explanatory Power of Structural Realism in the 21st Century: the Eastern Partnership, Russian Expansionism and the War in Ukraine

While the scope of the paper is to assess the actions undertaken by the European Union towards the FSU-CIS (the former Soviet Union, Commonwealth of Independent States) which was manifested through the Eastern Partnership Initiative in the years 2008–2014, the focus will be centred on theoretical concepts and their ‘explanatory power’ rather than actions undertaken by European or Russian decision makers. Taking that into the account, this essay will critically assess the explanatory power of the neorealist school of thought which although overtly criticized, still remains a viable tool in explaining the processes occurring in international relations.
