Senior U.S. Military Leaders Warn Defense Secretary Pete Hegseth That Iran War Is Unsustainable

In the August 14 edition of the classified Secretary of Defense Orders Book (SDOB), the chiefs of the Army, Navy and Air Force—along with the four-star commanders of U.S. European, Indo-Pacific and Southern Commands—recorded formal “non-concurrences” with Defense Secretary Pete Hegseth’s order to keep more than 50,000 troops in the Middle East through September and, for some units, until 2027. The commanders warned that the prolonged allocation of ships, aircraft, missiles and personnel to the Iran campaign is eroding the United States’ ability to train, conduct homeland-defense missions and respond to crises elsewhere. They indicated they would nevertheless execute the orders despite their objections.

President Donald Trump has pressed Tehran to reopen the Strait of Hormuz and has signaled that all military options remain on the table. Since the conflict began six months ago, the Pentagon has redirected a substantial share of its global force structure to support operations against Iran, including redeploying the aircraft carrier USS George Washington from Japan and moving the THAAD missile-defense system from South Korea to the Middle East. The sustained focus on Iran has coincided with a broader debate within the defense establishment over Secretary Hegseth’s leadership style and personnel decisions.

The commanders’ warnings highlight a strategic dilemma: maintaining pressure on Iran while preserving the United States’ capacity to deter other adversaries, notably China and North Korea, and to protect the homeland. The reduction in destroyer availability and the depletion of missile stockpiles constrain the Navy’s ability to conduct simultaneous operations in multiple theaters. Likewise, the loss of a quarter of the Reaper fleet limits persistent intelligence, surveillance and reconnaissance capabilities that are critical for both regional and global missions.

Sources differ on the stance of the Army and Air Force. The precise nature of their objections—whether formal non-concurrences or risk-focused cautions—remains unclear.
