To the contrary, the borders must be controlled absolutely, as is the right of every sovereign nation. It is hardly impossible and would demand no more than adding to the Border Patrol a paramilitary force of roughly 30,000, equipped with vehicles, helicopters, unmanned aerial drones, fences, and sensors. Crowded and slow entry points should be expanded to provide quick and thorough inspection by traditional methods and inspection to the limits of technological advance where traditional methods are impossible, as in searching the interstices of vehicles, or packed cargo containers, for nuclear or chemical warfare material. The sea frontiers can be secured if we undertake to supplement the Coast Guard with a few dozen high endurance cutters, 100 coastal patrol vessels, 50 long-range reconnaissance aircraft, 100 helicopters, and the appropriate additional personnel; and if the navy, by expansion of its anti-submarine assets, fixed and afloat, guarantees against submarine infiltration.
