Healthy boundaries: remedies for Europe’s cross-border disorder

The migration crisis that engulfed Europe in 2015 highlighted the EU’s vulnerability when faced with major instability and disruption at its borders. Although the Union has internal and external security arms – comprising the ten home affairs agencies that underpin its Area of Freedom, Security and Justice (AFSJ), on the one hand, and the international missions undertaken under the Common Security and Defence Policy (CSDP) on the other – it still struggles to deploy these instruments effectively.

This Chaillot Paper examines how the EU, bearing in mind its evolution as a multinational bureaucratic organisation rather than a traditional state actor, can successfully develop meaningful security capabilities. It explores possible new formats for AFSJ-CSDP cooperation, outlining four options for joint deployment: ‘demar­cated’, ‘sequential’, ‘modular’ and ‘integrat­ed’.  Stressing the importance of a clear-eyed diagnosis of the changes underway in the global security environment, the paper explores how these four joint security formats might be adapted to address crises with maximum effect.
