US-Colombia security ties have strengthened under President Abelardo de la Espriella, who took office in August 2026 after defeating the Petro-aligned candidate. The Trump administration has shifted from earlier threats of action against the prior government toward joint counternarcotics efforts, including memoranda on critical minerals and civil nuclear cooperation, US provision of MQ-9 Reaper drones, and Colombian-led task forces targeting ELN and FARC dissident groups. US strikes to date have targeted suspected drug vessels in international waters under operations like Southern Lance, without crossing into Colombian territory. Recent internal attacks by armed groups in Cauca have not altered the bilateral alignment. Traders price a US-initiated strike on Colombian soil by December 31 at roughly 19-25 percent, reflecting the emphasis on partnership over unilateral action.
