President Trump has issued a warning about the potential for renewed fighting with Iran, as the U.S. military has already fired more than 60% of its key Patriot and THAAD interceptors during the ongoing conflict that began on February 28. The Pentagon is now requesting $67 billion in supplemental funding to address significant munitions shortfalls, with current stockpiles of Patriot missiles dwindling to as few as 759. The Defense Department is working to accelerate production of interceptors, but Trump has criticized the Biden administration for leaving the U.S. with an insufficient inventory after sending arms to Ukraine without proper replacements.
