**Strong bilateral security cooperation and Colombia's explicit invitation for U.S. joint operations against drug cartels and designated terrorist groups underpin the 97.1% trader consensus against a U.S. invasion in 2026.** Following the August 7 inauguration of President Abelardo de la Espriella, the two governments rapidly advanced agreements under Plan Patriota 2.0 and the Shield of the Americas coalition, including intelligence sharing, aerial eradication, extraditions, and potential coordinated strikes on Colombian soil with Bogotá's authorization and $1 billion in U.S. security assistance. This builds on decades of alliance rather than conflict, following earlier 2025-early 2026 tensions under the prior administration. An invasion would require unilateral action against a sovereign partner government, a scenario unsupported by current diplomacy, policy priorities, or military posture. Late-year shifts such as breakdowns in the new partnership, major border escalations, or unforeseen leadership changes could theoretically alter dynamics, though no such catalysts appear imminent.
