Defense Secretary Pete Hegseth’s ongoing purge of top military leaders has left the U.S.
A sweeping leadership crisis at the Pentagon has left the U.S. Army navigating its busiest operational period since the wars in Iraq and Afghanistan without its top permanent officer. The turmoil follows the dismissal of Gen Randy George in April by Defense Secretary Pete Hegseth without public explanation.
Since taking office in January 2025, Hegseth has forced out at least half a dozen senior officers, shrinking the number of active four-star generals from 10 down to just five. The departed leadership includes Army Vice Chief of Staff Gen James Mingus, Gen David Hodne, Major General William Green, Gen Christopher Donahue, and Air Force Vice Chief of Staff Gen James Slife. Additionally, Gen CQ Brown Jr. was removed from his post as chairman of the Joint Chiefs early in Donald Trump’s second term, while Gen David Allvin retired last fall.
Strained Middle East Operations and Dropping Four-Star Ranks
The leadership vacuum coincides with severe military pressure in the Middle East, where U.S. bases face attacks from Iranian drones and missiles. An Iranian missile strike on prefabricated housing at a U.S. base in Jordan killed three American soldiers and injured more than 100 on July 17, while a separate drone strike in Kuwait killed six soldiers.
The Army’s air-defense units, including Patriot missile crews, are playing a vital role in shielding troops from incoming fire. Yet the leadership changes have directly impacted key commands. Hegseth reduced Gen Christopher T. Donahue’s command overseeing U.S. ground troops in Europe from a four-star to a three-star position, a demotion that could force his retirement if he fails to secure another four-star assignment. Donahue’s command had previously trained drone-defense teams using tactical lessons drawn from the war in Ukraine.
Civilian Leadership Departs Amid Pentagon Tension
Civilian oversight is also fracturing at the highest levels. Army Secretary Daniel P. Driscoll, the service’s top civilian official, is expected to step down by the end of the year and has already moved out of his rented family home at Fort Myer near Washington. Driscoll and George had previously collaborated on modernizing the Army for a battlefield dominated by drones and assisting administration efforts to broker a peace deal in Ukraine.
Lawmaker Warnings and the Defense Department Response
The purges have drawn sharp public criticism from lawmakers who argue that removing experienced commanders during an active conflict degrades institutional stability. Representative Pat Ryan warned that the administration’s actions threaten both troop safety and the military’s nonpartisan traditions.
Ryan further cautioned that the systematic removal of top brass inflicts lasting harm on the armed forces. We’re doing generational damage to the sense that the military is an apolitical trusted organization that swears an oath to the Constitution, not to a president,
he added.
The Pentagon’s leadership has declined to address specific personnel departures. While Hegseth’s office directed inquiries to the military branches, the Army declined to comment on Driscoll’s status, stating it does not speculate on leadership changes. Cynthia O. Smith, an Army spokeswoman, defended the current command structure in an official statement.
Smith added that remaining officials are actively driving the Army’s mission forward, ensuring that strategic objectives, modernization programs, and global readiness remain uninterrupted.
