Security and stability scenarios for the Western Balkans

In short
  • Security threats in the Western Balkans arise from Serbia-Kosovo tensions, ethno-nationalist political agendas, weak governance, climate change, organised crime, and malign foreign influence.
  • As concerns about broader unrest or conflict in the Western Balkans remain, the need to assess the region through a security lens continues.
  • The EU, NATO, and the Netherlands have many instruments to promote security and stability, but several need strengthening to address all challenges.

Are the EU, NATO, and the Netherlands prepared?

 

This report has examined how the Netherlands, the EU and NATO can enhance their security approach to address potential security developments in the Western Balkans in the period up until the end of 2029. Therefore, it has first assessed the current security and stability situation in the Western Balkans, displaying current threats to territorial, physical, economic, ecological, social and political, and international (legal) security and stability.

''The current tensions in Bosnia and Herzegovina after the conviction of Bosnian-Serb leader Milorad Dodik show that broader instability in the Western Balkans remains a real risk. Our latest report doesn’t just look at the chances of (armed) conflict—it also explores how climate change, organized crime, and economic and democratic developments shape the region’s long-term stability. The EU and US play a key role in tackling security challenges in the Western Balkans, but their sustained cooperation will be crucial'', reasercher Wouter Zweers says.

Especially the lack of normalisation between Serbia and Kosovo and persisting secessionist agendas and a lack of reconciliation in Bosnia and Herzegovina, as well as a manifestation of ethnic tensions and organised crime have in the last few years threatened physical and territorial security in the region. The report also highlights continued weaknesses in the democratic governance of the Western Balkan countries, which also negatively impact economic stability and bring about migrationrelated security challenges. The region’s ecological security is mainly threatened by (climate change-)induced natural disasters, environmental pollution, as well as insufficient energy security. Lastly, stability is undermined by external actors such as especially Russia, but also by the effects of the war in Ukraine, heightened global geopolitical tensions, global pressure on democracy and uncertainty surrounding transatlantic cooperation.

Subsequently, the report has presented (the synopses of) four scenarios that showcase fictional but potential security developments in the Balkan region over the next five years. Two of those scenarios foresee a violent escalation, respectively in Bosnia and Herzegovina and in North Kosovo. The other two scenarios see, respectively, a relatively successful EU integration path marked by external security challenges, and a muddle-through scenario with an intensification of several already persistent security challenges
