The European Union can hardly contain its pleasure at the arrest of Radovan Karadzic, the murderous Bosnian Serb leader who was picked up in Serbia on Monday after 11 years on the run. For all those who believe the best way to ensure long-term stability in former Yugoslavia is to accelerate Serbia’s path to EU membership, Karadzic’s arrest was cause for celebration.
The arrest appears to vindicate the EU’s strategy over the past year of overtly supporting pro-EU political forces in Belgrade. The aim is twofold: to neutralise the militant nationalists who have poisoned Serbian public life for the past 20 years, and to persuade Serbian voters that their best hope of a decent future lies in aligning their country with the EU.
This strategy, so it is argued, helped secure victory in last February’s Serbian presidential election for Boris Tadic, the pro-EU incumbent. Likewise, the signing of an EU-Serbia pre-accession agreement in late April is said to have tipped the balance in favour of the pro-EU camp in Serbia’s parliamentary elections two weeks later.
The implementation of the pre-accession accord requires Serbia to be certified as being in full co-operation with the UN war crimes tribunal in The Hague. Two war crimes suspects - Ratko Mladic, the Bosnian Serb wartime general, and Goran Hadzic, the Krajina Serb leader - are still fugitives. But Karadzic’s arrest is an undeniable breakthrough and deserves a reward. It is not impossible that Serbia will be declared an official candidate for EU membership before the end of this year or in 2009.
Before the celebrations get out of hand, however, we need to recall that Serbia faces formidable obstacles on its road to the EU. One is its readiness in terms of economic performance, the rule of law and its ability to meet a vast range of EU technical standards.
Another concerns Kosovo, whose secession from Serbia and declaration of independence in February has been recognised by most EU countries but is rejected even by the most pro-EU politicians in Belgrade. The Serbia-Kosovo dispute is very far from settled. The EU will think twice before repeating the mistake it made with Cyprus in 2004 and admitting a country in advance of a solution to its internal political and territorial quarrels.
Lastly, French President Nicolas Sarkozy and German Chancellor Angela Merkel have stated flatly that further expansion of the EU is out of the question until the Lisbon treaty on institutional reform comes into effect. In other words, the door will be blocked to Serbia until Ireland reverses its rejection of the Lisbon treaty in last month’s referendum.
Putting pressure on an island in north-western Europe seems a curious way to go about promoting stability in south-eastern Europe. But perhaps for now we should just be happy that Karadzic is behind bars.
