Concern about the so-called ‘crime–terror nexus’, a centrepiece of discussion, debate and research in the counterterrorism field, has yielded a vast body of academic and policy literature regarding the nature of symbiotic relationships between organised criminal formations and terrorist organisations. Recognising a spectrum of possible synergies – including direct interactions between criminals and terrorists, the adoption of criminal tactics by terrorists, and even the merging of these artificial categories altogether in certain cases – regard for the ‘crime–terror nexus’ has largely ignored the question of whether and how relationships between crime and terrorism may yield opportunities for terrorist financing, particularly in the European context.
