This paper explores two divergent concepts installed in the EU operational structure – postmodernism and modernism – in relation to the CFSP and enlargement. The research is conducted upon the content analysis method, descriptive method and comparative analysis. The main research intention is to locate the inability of the EU, to achieve internal coherence on a certain international issues, taking into account the clash between the above mentioned concepts. Consequently, this paper locates the problem of modernism as in the EU normative provisions and behavior of its Member States. At the end, it is noted that the concept of avant-garde Europe can be used as a possible solution for future development of the EU in a postmodern direction.
