US army secretary resigns amid signs of Pentagon unease with Iran war The US Army's top civilian leader, Dan Driscoll, has submitted his resignation, the White House confirmed on Monday, following reports of tensions with Secretary of War Pete Hegseth. "Driscoll has been highly effective in advancing President Trump's agenda to Make America Strong Again at the Department of the Army," Anna Kelly, the White House deputy press secretary, said in a statement on Monday. "The United States Army is more powerful than ever thanks to his work alongside the Commander-in-Chief and Secretary of War,” she added. Driscoll’s departure comes at a time of signs there is unease in the Pentagon over how the Trump administration is prosecuting the war on Iran. The heads of the army, navy and air force, and the four-star commanders overseeing US operations throughout Europe, Asia and Latin America, warned Hegseth that any prolonging of major operations would weaken the US’s ability to confront other foes, the Washington Post reported on Monday. The Associated Press reported earlier this month that the war on Iran has caused a "beyond critical" shortage of advanced missile interceptors, especially Patriots, which have been used to shoot down Russian ballistic missiles in the Ukraine war. The US has also exhausted its stockpile of sophisticated long-range missiles and has “virtually" used up its supply of surface-to-surface weapons, including ATACMS and Precision Strike Missiles (PrSM), Reuters reported.
