MARY LOUISE KELLY, HOST:The war with Iran has seriously depleted U.S. missile stockpiles, both offensive and defensive. Now, we've talked on this program before about the stockpile of defensive Patriot missiles. KELLY: OK, what are these Army missiles that we're talking about? But two months earlier, he said it's going to take months or years to rebuild missile stockpiles. Ambassador Mike Waltz on NBC's "Meet The Press" said Patriot missile stockpiles were depleted because President Biden sent too many to Ukraine and also used them to defend against the Houthis.
