President Donald Trump said on Thursday the United States has a vast supply of munitions and threatened those who suggested otherwise with jail terms as his frustration with the Iran war boiled over.

The Republican leader lashed out on his Truth Social platform at media reports about the dwindling weapons stockpile, saying that the United States has “massive amounts of ‘munitions’ especially of certain types,” without giving further detail.

“Additionally, large amounts are being manufactured and shipped to the U.S. as needed. Defense companies are building the largest number of plants and factories in our country’s history,” he said.

The Washington Post reported that Trump demanded answers about the munitions shortages from Pentagon chief Pete Hegseth last Friday, when they attended a cabinet meeting at the Camp David presidential retreat.
