The End of American Sanctuary: New Threats Demand a New Homeland Defense

Foreign Affairs | Seth G. Jones

American air and missile defenses face unprecedented vulnerability as China, Russia, and North Korea expand intercontinental strike capabilities alongside low-altitude drone and cyber threat vectors. Recent foreign conflicts demonstrate that nuclear arsenals no longer deter conventional homeland strikes, leaving critical U.S. infrastructure exposed. Interceptor shortages severely compound this vulnerability, with global military supplies of THAAD dropping by up to 80 percent and Patriot interceptors by 50 percent.

Domestic legal frameworks and fragmented interagency protocols further obstruct local authorities from countering unauthorized drone incursions above sensitive installations, such as Barksdale Air Force Base. Concurrently, agentic AI platforms threaten to automate and accelerate state-sponsored cyber sabotage against power grids and municipal water systems. U.S. defenses remain porous. Confronting these multi-domain risks requires rapid integration of active air defenses, layered passive hardening, expanded legal authorities for local counter-drone operations, and a unified National Counterintelligence Center.

Comment

Federal airspace restrictions under Title 10 severely constrain rapid threat responses during low-altitude aerial incursions. The drone swarms detected over Barksdale Air Force Base demonstrated how statutory limits prevent local base commanders from deploying immediate electronic jamming. Operational coordination stalls within Department of Defense and FAA authorization channels before ground counter-UAS systems can fire.

This authority gap leaves strategic assets like the B-52 fleet vulnerable to launch-container attacks executed from nearby civilian roads. Expanding the Safer Skies Act of 2025 would shift local counter-drone execution toward state law enforcement agencies. Consequently, defensive doctrine is moving toward delegating active engagement authority directly to military personnel operating Coyote interceptors.

Strategic Question for Discussion
If federal engagement permissions under Title 10 remain restricted, how effectively can decentralized deployments of Coyote interceptors protect installations like Barksdale Air Force Base against multi-directional drone incursions?
The operational pattern suggests that technological deployments of systems like Coyote will yield limited defensive value without statutory reform to Title 10 engagement rules. Multi-agency authorization delays inevitably miss the narrow engagement window required to neutralize low-altitude swarms before impact. My assessment is that defensive efficacy around strategic assets like Barksdale Air Force Base will ultimately depend more on delegated command authority than on sensor density.
