During the 1979-1980 hostage crisis, a defiant Iran starkly demonstrated the limits of American power. Back then, when the post-Vietnam military was at a low ebb, we didn’t strike Iran, and a long-shot rescue operation ended in abject failure. We’re running low on missiles and interceptors in a months-long conflict with a beleaguered second-rate power. On top of this, news organizations are reporting that we are almost out of ATACMS — a ground-launched precision-strike missile — and Precision Strike Missiles, the newer, longer-range successor to ATACMS. According to media reports, we’ve used about half our supply of Tomahawk cruise missiles, when we’ve been manufacturing fewer than 100 a year.
