The Pentagon’s inventory problem stopped being a classified worry this week and became a published number. Roughly four fifths of the THAAD interceptor stock is gone against pre-war levels. About half the Patriot stock. Sources with access to the tallies say virtually the entire global holding of long-range precision strike missiles has been fired, along with nearly all the Army’s ATACMS and Precision Strike Missile rounds. Those are not marginal categories. They are the two things the United States needs to force a waterway open and then survive what comes back.
