US-Colombia security cooperation has intensified under President Abelardo de la Espriella, with Bogotá joining the US-led Shield of the Americas counter-cartel coalition and authorizing joint operations against armed groups. Over 300 US troops conducted joint exercises through November 11 focused on counter-narcotics, illegal mining, and drone threats at the Tolemaida base. A November 7 drone attack on a Colombian army base that killed three soldiers and wounded at least 16 forms part of escalating violence from groups such as the ELN and Gulf Clan, prompting Colombian airstrikes. High-level US visits, including Joint Chiefs Chairman Gen. Dan Caine on November 10 and Vice President JD Vance later in the month, underscore bilateral coordination. These developments shape trader assessments of any direct US military action on Colombian territory.
