US-Colombia security cooperation has intensified under President Abelardo de la Espriella, with Washington providing MQ-9 Reaper drones, intelligence support, and over 300 troops for joint training exercises through mid-November 2026 focused on counter-narcotics, drone threats, and border operations. The US has assisted Colombian and Venezuelan forces in targeting ELN camps, including a late-October strike that killed at least 19. In response, ELN carried out a November 7-8 drone attack on a Colombian army base in Santa Rosa del Sur, killing three soldiers and wounding 16, prompting Colombian airstrikes and vows of expanded operations. High-level visits, including US Joint Chiefs Chairman Gen. Dan Caine on November 10 and Vice President JD Vance later in the month, underscore ongoing alignment rather than direct US military action inside Colombia. These developments frame trader assessments around sustained partnership amid rising internal conflict with armed groups.
