Commands warn fentanyl and cartels remain major homeland threats; interdiction improves but gaps persist

Summary
NORTHCOM and SOUTHCOM leaders told the House committee that interdiction activity is at record pace for some drugs, that fentanyl deaths remain high, and that maritime and intelligence gaps limit how much trafficking can be stopped.
House members pressed U.S. Northern Command and Southern Command leaders about the flow of narcotics and the lethal toll of fentanyl during the posture hearing.
Admiral Alvin Halsey, commander of U.S. Southern Command, said maritime interdiction operations are on a record pace: "we have been very deliberate with JAD of South which is a gold standard for interdiction and they have been able to stop record pace at this point. Over 190 metric tons. We're on a record pace to exceed what we did last year." He also told the committee "we typically can action about 10% of what we see" when asked what fraction of trafficking SOUTHCOM can interdict with available assets.
General Greg Guillot of NORTHCOM testified that sealing parts of the southern border has changed cartel behavior and increased violence as groups seek alternate routes and markets. He described two adaptations: cartels attempt new routes to move people and drugs, and competing groups have increased violence when access is restricted.
Committee members cited mortality statistics during opening remarks; one member noted that "in the 12 months ending October 2024, over 52,000 Americans died from fentanyl overdoses." Witnesses described interagency and partner‑nation efforts to reduce flows. Guillot described a newly created Joint Intelligence Task Force — Southern Border that fuses interagency and DOD intelligence to improve detection and targeting of smuggling networks. Salasas and others said the department continues to study precursor flows into Mexico and the region and to shift operational posture to follow production and transit points.
Witnesses and members agreed on capability shortfalls. Admiral Halsey said more maritime and ISR assets would enable a higher interdiction rate, and several members pressed for additional persistent presence and partner capacity building. The panel also discussed precursor chemicals and the need to disrupt laboratory production in Mexico and other countries rather than only intercept finished shipments at the border.
Ending note: commands reported record interdiction tonnages for some drugs and new intelligence fusion efforts, but they said the United States still lacks the persistent assets needed to interdict a larger share of trafficking and precursor flows.
