The post-Yugoslav states share two commonalities at least: their common legacy as part of Yugoslavia, and their aspired political future in the EU. The easy guess – therefore – is that foreign policy convergence would carry the day. Yet, when comparing Slovenia to Serbia and Croatia to Bosnia, it is obvious that divergence matters and each of these states has developed into different directions. The paper will systematically compare the foreign policies of Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, Macedonia and Kosovo, drawing on insights from extensive foreign policy studies of the respective countries. As the focused and structured comparison is apt to demonstrate unconsolidated state- and nation-building projects continue to influence foreign policy decision-making and implementation.
