Recent joint U.S. military and law enforcement participation in Ecuadorian police raids against Jalisco New Generation Cartel-linked networks in September 2026 marked a shift toward direct ground involvement on foreign soil, following earlier 2026 operations there and maritime interdictions. The Trump administration has designated multiple cartels as foreign terrorist organizations, formed regional coalitions for coordinated action, and expanded Southern Command posture, with officials stating all options remain available including potential land strikes. Tensions along the U.S.-Mexico border have prompted mirrored troop deployments and anti-drone measures, though Mexico has limited direct U.S. combat roles on its territory due to sovereignty constraints. Upcoming developments include further coalition exercises and any new bilateral agreements that could expand operational scope.
