President Trump recently visited San Diego to inspect prototypes for an expanded and more resilient border wall. The eight prototypes on display are all massive structures, some 30 feet high and extending six feet underground. They are designed to be unscalable and extremely difficult to breach. The new barrier system is intended to replace existing, less robust walls and to secure some unfenced portions of the border.
While most attention has been focused on the practical and symbolic value of a physical wall, it has long been recognized by the president and senior members of his administration that a barrier system alone would not suffice to secure the border. In his 2017 confirmation hearings, former Secretary of the Department of Homeland Security (DHS), General John Kelly, stated that "a physical barrier in and of itself cannot do the job, it has to be a layered defense."
