In addition, within the global order of interdependence, a regional approach to security have become increasingly important. As a result of the US-led War on Drugs, Colombia has become apparent for its role as a security exporter in the ‘South-South’ context. However, what has been neglected in academia, is the wider convergence in Latin America concerning the altered regional security environment and the drivers that allowed the shift from traditional ‘North-South’ towards ‘South-South’ intelligence cooperation. This paper presents the application of Regional Security Complex Theory towards Colombia’s geopolitical position and liaison relationships in 21st-century Latin America. By examining English as well as Spanish news sources and academic research, it shows that a variety of interrelated push-and-pull factors and have caused Colombia’s emerging disintegration from the South American Regional Security Complex. More importantly, it reveals that the War on Drugs resulted in Colombia becoming a benchmark in anti-narcotics security and intelligence cooperation and the ‘Colombianization of Mexico’. Ultimately, it caused wide-ranging bilateral intelligence initiatives between Colombia and Mexico as well as triangular agreements in which Colombia acts as a proxy for United States interests. These patterns of amity culminated in Mexico becoming the largest recipient of security and intelligence cooperation from Colombia worldwide.Show less
