President Donald Trump and Defence Secretary Pete Hegseth dismissed or forced the retirement of more than a dozen senior commanders across the US military since 2025. The purge included Army Chief of Staff Gen. Randy A. George, Army training commander Gen. David Hodne, Chief of Naval Operations Adm. Lisa Franchetti, the Director of the Defense Intelligence Agency Lt. Gen. Jeffrey Kruse, Maj Gen William Green of the Army’s Chaplain Corps, and even the chairman of the Joint Chiefs of Staff Gen. C.Q. Brown Jr.[1]

Reports suggested that Hegseth wanted leaders who would fully implement the administration’s vision and reject diversity and inclusion programmes.[2] At the same time, it is argued that officers were punished for warning that war plans were flawed or for refusing to remove Black and female officers from promotion lists.[3] The scale and timing of the purge are almost unprecedented in US history. Prior wartime removals targeted individual commanders for insubordination rather than restructuring the entire senior leadership. This brief examines how the purge compares with earlier removals, explores the demographic and religious composition of the US armed forces, and explains why DEI (Diversity, Equity and Inclusion) programmes are vital for military readiness and strong civil–military relations.

In a democratic country like the US, elected leaders set national policy, while uniformed professionals plan and execute operations.  As the war with Iran expanded in 2025–26, the Trump administration dismissed senior officers as highlighted above. Political appointees argued that commanders who opposed the war plan or defended DEI policies were obstructing victory. The purge has raised questions about the balance between civilian authority and professional military advice, the role of DEI initiatives in force readiness, and the health of civil–military relations.

Historical Context: Firings vs Purges

Purges in the name of curbing corruption, along with investigations against top military leaders, are frequent in China. However, it is not a regular occurrence in the US military, and even less so in the middle of a war. There are only a few considerable instances in the past where military leadership was removed.

During the Korean War, Gen. Douglas MacArthur proposed bombing China and publicly criticised President Harry Truman’s policy of limited war. Truman relieved MacArthur, arguing that MacArthur could not give “full support” to the US and UN policies.[4] The decision affirmed that military leaders must adhere to civilian strategy, though it sparked public controversy.

More recently, General David McKiernan was removed from command of the International Security Assistance Force in Afghanistan in 2009 by then US Defense Secretary Robert Gates because the US required a shift from a relatively conventional, force-protection-oriented approach to a more aggressive counter-insurgency and special-operations-driven strategy against the Taliban.[5] In Afghanistan, Gen. Stanley McChrystal and his aides disparaged senior civilian leaders in a Rolling Stone article. President Barack Obama accepted McChrystal’s resignation, emphasising that the dismissal stemmed from conduct undermining civilian control rather than policy differences.[6]

These examples highlight targeted dismissals based on insubordination or unacceptable conduct, as well as strategy-driven reasons. The recent purge differs both in scale and motivation. Unlike the removals of MacArthur, McKiernan and McChrystal, the recent purge swept away an entire upper command echelon across services. It replaced them with officers who share the administration’s ideological alignment. Past firings were about preserving civilian supremacy; the current purge, according to multiple officials familiar with the decisions, is driven by ideological grievance, personal rivalry, and an unrelenting demand for political loyalty.[7]

Political Climate and Warrior Ethos

Domestically, the war against Iran has coincided with President Trump’s second term and Hegseth’s push to end DEI programmes. Hegseth argued that these initiatives distracted from combat readiness and cultivated “wokeness”. Critics countered that the........
