Another U.S. vulnerability is its “magazine depth.” The military has top-of-the-line guided missiles but procures few of them. Last year the U.S. reportedly produced only 96 THAAD air-defense missiles, 54 Precision Strike Missiles and 57 Tomahawk cruise missiles. It will take years and billions of dollars to replenish stockpiles, leaving us less prepared for a conflict against Russia or China in the meantime.
