**US strike on Mexico by December 31?** Trader consensus assigns this outcome a low probability, reflecting sustained but contained escalation in counter-cartel efforts. President Trump has publicly stated that cartels effectively govern Mexico and warned of intensified land-based action, following US missile strikes on suspected drug vessels at sea and a late-September border incident in which suspected cartel members reportedly fired on a US Coast Guard vessel near the Rio Grande. In response, the US deployed roughly 500 troops to the Texas border area, while Mexico disputed the gunfire claims, deployed its own forces under “Operation Mirror,” and reiterated firm opposition to any US military operations on its sovereign territory. Bilateral cooperation remains focused on intelligence sharing, maritime patrols, and Mexican-led enforcement, with US pressure for joint raids or expanded authorities unmet. Recent Pentagon moves—such as troop rotations for training in Central and South America and drone reallocations—signal broader regional pressure without crossing into Mexican soil strikes. No qualifying aerial, drone, or missile strikes on Mexican territory have occurred, and Mexico’s consistent rejection of intervention continues to limit near-term prospects for resolution to “Yes.”
