According to a report in the New York Post, Defense Secretary Pete Hegseth is engaged in a purge of top Pentagon leadership, driven by his fear of being replaced by Army Secretary Dan Driscoll. Hegseth has already demanded the resignation of Army Chief of Staff Gen. Randy George, a close aide to Driscoll, citing unspecified reasons. Sources say Hegseth is concerned that Driscoll is a top contender to succeed him, and is preemptively targeting Driscoll's allies in an attempt to secure his own position.

Why it matters

This power struggle at the highest levels of the U.S. military leadership comes at a sensitive time, with the country engaged in an ongoing conflict with Iran. The instability and infighting could have serious implications for the conduct of the war and national security more broadly. It also raises questions about the decision-making process and accountability within the Pentagon.

The details

According to the report, Hegseth's actions are driven by the 'insecurity and paranoia' he has developed since the 'Signalgate' controversy in March 2025, which resulted in the ouster of then-National Security Adviser Mike Waltz. While Hegseth emerged unscathed from that incident, sources say he now fears he may be on thin ice and is trying to preemptively remove potential replacements, particularly Army Secretary Dan Driscoll, whom he sees as a natural contender for his job. Hegseth has been told by the White House that he cannot fire Driscoll directly, so he has instead been targeting Driscoll's close allies, such as Army Chief of Staff Gen. Randy George.

What’s next

It remains to be seen whether Hegseth's purge of Pentagon officials will succeed in undermining Army Secretary Driscoll's position, or if it will further destabilize the military leadership at a critical time. The White House's response to Hegseth's actions will also be closely watched.
