US President Donald Trump said the United States held near-unlimited stocks of ammunition and was producing munitions at record levels, rejecting reporting that the war with Iran is straining American firepower, in a post on his Truth Social platform on September 3.

Trump said the US had "virtually unlimited" mid- to high-grade ammunition, "far more than we could ever use" for the Iran campaign or any other war, which he called highly unlikely. He said the country was producing munitions at levels never seen before and stockpiling for any contingency.

The statement follows weeks of reporting that a war pitched as quick and decisive is now consuming munitions and troop deployments at a rate that has concerned Pentagon planners and Republican allies ahead of the November midterm elections. Trust in US supply levels has become a live question as the conflict enters its seventh month, and Trump attacked the outlets raising it in personal terms.

The US was keeping the munitions for itself rather than selling them, Trump said, though sales to allies would soon resume.

He claimed the Biden administration had given Ukraine more munitions, free of charge, than the US had used in Iran, and said Washington would belatedly seek to recover from Europe hundreds of billions of dollars in aid provided to Ukraine and Nato.

The claims could not be independently verified by IntelliNews, and no evidence was provided for the figures in his latest outburst on his privately-owned messaging application.

Trump's latest remarks followed The Wall Street Journal's reporting that he has privately discussed declaring the war over as advisers warn of political backlash, even as the Pentagon extends Middle East deployments as bond yields continue to increase across the world over increased tensions in the Gulf. 

Trump has previously played down concerns that the conflict is draining US firepower, calling it a "small war," and adding that Iran's top leadership was eliminated at the beginning of the war on February 28.

The war started when the US and Israel launched strikes on Iran and killed Supreme Leader Ali Khamenei and several other top security and political officials and sites.

Iran responded by closing the Strait of Hormuz, through which about 20% of the world's oil and gas passed before the conflict. US Central Command said it struck IRGC targets in Iran on September 1.
