Although the Western Balkan countries followed a similar historical path under socialism, replaced by an exhausting period of political and economic transition, they are not equally prepared to be members of the European Union. With the divisions of the countries among the frontrunners and lagers, as repeated at the Sofia Summit, the process of EU enlargement will result with many fierce consequences and will lead to additional years of isolation and decades of strained relations. On the Bosnia and Herzegovina, Macedonia and Kosovo road towards EU integration precedes deep and complex constitutional settlement, in which creation EU played one of the major roles. Even though the regatta principle is a current mechanism on which each of the countries is assessed on its process of integration, it seems that a common WB6 entrance in the EU is the most feasible scenario. In that way, for a more prosperous and unified Western Balkans and for a secure and finally completed European Union, Catch-all, or a Little Bang Approach is the best solution for the stakeholders.
