The U.S. chairman of the joint chiefs of staff, Gen. Dan Cain, expressed concern to President Donald Trump about a shortage of critical ammunition and lack of allied support, which would add risk to a possible operation against Iran. This was reported by The Washington Post, citing sources involved in the conversations. According to the report, in a meeting held last week at the White House, Cain argued that U.S. ammunition stockpiles have been depleted as part of the ongoing defense of Israel and support for Ukraine. It was also claimed that only hundreds of THAAD and Patriot missiles used by defense systems have been produced, far fewer than what would be required for a war against Iran.
