Inside Pete Hegseth’s Pentagon Shake-Up

Since taking office in January 2025, Defense Secretary Pete Hegseth has removed, pushed out, or blocked the promotions of roughly 20 generals and other top military leaders—a pace of personnel change that one Republican senator called grounds for firing him. The departures include the chairman of the Joint Chiefs of Staff, the Army chief of staff, the first female leader of the Navy, and the commander who oversaw the Afghanistan evacuation. To an outside observer, this might look like standard turnover when a new boss arrives. But as Wall Street Journal national security reporters Michael Gordon and Laura Seligman explain, the U.S. military is not a typical workplace, and these changes strike at how the institution selects its leaders, maintains its apolitical character, and prepares for future threats.

Show Notes

In his first year atop the Pentagon, Pete Hegseth rebranded himself as a secretary of war, not defense. And the changes didn’t stop there. Under his leadership, the department has announced that all “warfighters” 30 and older will be tested for testosterone deficiency, and that they would be judged on their appearance and grooming. But possibly the most profound change has been a shake-up in the highest ranks of the armed forces. Top officers—especially in the Army—have been stymied, pushed out or fired. Michael Gordon and Lara Seligman join host Alex Ossola to discuss Hegseth’s approach, as well as the possible consequences of fast turnover in the highest echelons of the world’s most powerful military.
