In public debates, “terrorist groups” and “drug cartels” are often portrayed as two separate categories of threat: the former ideologically motivated, the latter profit-oriented. Various studies, however, indicate that today’s reality is significantly more complex. In several regions, from West Africa and the Sahel to Europe and Latin America, security analyses show that terrorist organizations and actors within organized crime are intertwined in key areas. Overlaps can be observed in routes, service networks, financial channels, and occasionally even tactical methods.
