US-Colombia security cooperation has intensified under President Abelardo de la Espriella, with joint counter-narcotics training, US-provided MQ-9 Reaper drones, intelligence sharing, and recent high-level visits by officials including Secretary of State Marco Rubio. These developments, alongside US maritime strikes on drug vessels in international waters and Colombian-led operations against groups like the ELN and Gulf Clan, have shaped trader consensus reflected in current Polymarket pricing of roughly 15-23% for a US-initiated drone, missile, or air strike on Colombian soil by December 31. Upcoming bilateral engagements and continued focus on regional alliances further support the low implied probability, though escalation in anti-trafficking efforts could alter positioning before year-end.
