Inside Pete Hegseth’s Pentagon Purges: The Strategic and Cultural Overhaul of the US Military

US Secretary of Defense Pete Hegseth's ongoing restructuring of the military has led to significant high-level departures, raising concerns among experts about institutional readiness and long-term strategy. Earlier this week, US Army Secretary Daniel Driscoll resigned after attempting to directly appeal to US President Donald Trump regarding the impact of leadership changes on war readiness.

Driscoll, appointed last February to the highest civilian role in the Army below Pete Hegseth, played a key role in planning the Army's transition toward modern warfare assets like drones and missiles. His departure follows the removal or resignation of numerous top officials under Hegseth, including three- and four-star generals and members of the Joint Chiefs of Staff. The Trump administration has characterized some of these personnel shifts as undoing 'diversity, equity, and inclusion' initiatives that allegedly influenced past promotions.

Kelly Grieco, a senior fellow at the Stimson Center think tank, noted that while officials like Driscoll serve at the pleasure of the president, the high volume of firings raises questions about a potential hollowing out of senior military leadership.

Hegseth, a former Army National Guard infantry officer and Fox News television personality, assumed the defense portfolio with a mandate to increase 'lethality' and eliminate what he and Trump term 'woke' ideology within the Pentagon. The administration has renamed the department to the 'Department of War', removed public acknowledgments of minority and female pioneers, and introduced annual testosterone screening for soldiers aged 30 and over.

Critics, including Senator Jack Reed, argue that these changes are undermining a merit-based system and fostering a culture where personal allegiance supersedes competence. High-profile departures include General Charles Q Brown, Jr., Admiral Lisa Franchetti, General Randy A George, and General David Allvin. Civilian leaders such as Navy Secretary John Phelan and intelligence heads like Lieutenant-General Jeffrey Kruse have also exited their posts.

Experts warn that sidelining women and minorities and frequently replacing leadership disrupts crucial long-term initiatives, such as force modernization and adaptation to modern conflict dynamics, as highlighted by recent developments involving drones and missiles in the war in Iran.
