Although it’s been nearly a decade and a half since the Dayton Accord that brought peace to the Western Balkans, and ten years since NATO intervened over Kosovo, dangerous tensions persist. How great is the risk that old enmities and rivalries between Balkan newcomers to the EU and of NATO will spill over into wider policy areas? The argument for stabilising Balkan countries through integration into the EU and NATO remains strong, but with Euro-American relations still badly scarred by last year’s disagreements over the advisability of Georgian and Ukrainian NATO membership, how deep are the pitfalls? These questions are tackled by regional experts, academics and diplomats in the SDA's latest discussion paper, published thanks to the support of the Czech presidency of the EU.
