President Donald Trump confronted Defense Secretary Pete Hegseth at Camp David after learning that severe shortages of long-range missiles and air-defense interceptors were restricting America’s military options against Iran, according to The Washington Post.

Trump reportedly demanded to know why he had not been fully informed about the depleted stockpiles, telling Hegseth he believed the problem “had been fixed.” The shortages were reportedly one factor behind Trump’s recent decision to hold back another massive wave of strikes against Iran.

The most consequential impact is already being felt on the battlefield. U.S. commanders are reportedly rationing interceptor missiles by assessing where each incoming Iranian missile or attack drone is headed. Some projectiles believed unlikely to strike a protected military target or critical facility are being allowed to continue rather than consuming scarce Patriot or THAAD interceptors.

The scale of the depletion is significant. The Washington Post reported that U.S. forces fired more than 850 Tomahawk cruise missiles and over 1,000 Patriot and THAAD interceptors during the first month of fighting. More than 1,300 Army tactical ballistic missiles were also used during the opening weeks.

Reuters separately reported that the U.S. has used “virtually all” of its ATACMS and newer Precision Strike Missiles during the five-month war, along with slightly less than half of its global Tomahawk inventory. The shortage could force Washington to rely more heavily on piloted aircraft for future strikes, exposing crews to greater risk.

According to the Post, Hegseth blamed Deputy Defense Secretary Stephen Feinberg for failing to properly communicate the stockpile situation. The White House denied that any confrontation occurred, while the Pentagon called reports of depleted inventories and internal disputes “fictional.” Trump also insisted that the U.S. possesses “massive amounts” of munitions and warned that officials leaking classified stockpile information would face consequences.

The Pentagon is attempting to accelerate production. A new agreement exceeding $3 billion is intended to triple production capacity for Patriot components and quadruple it for THAAD, while another plan aims to raise annual Tomahawk production from approximately 60 missiles to as many as 1,000. Those increases, however, will take time and cannot immediately replace the weapons already expended.

The shortages now present Washington with a difficult calculation: how aggressively it can continue striking Iran while preserving enough missiles to defend American troops, Israel and regional allies—and retain sufficient reserves for a potential crisis involving Russia or China.
