Defense Secretary Pete Hegseth has removed or sidelined at least two dozen senior military leaders over the past nine months, a sweeping and unprecedented shake-up that has unsettled the armed forces. Many of the dismissals have come with little explanation and often against the advice of top military officials, creating an atmosphere of anxiety and mistrust among senior officers. Some leaders were targeted for their past associations, support for diversity initiatives, or for offering candid assessments that conflicted with administration narratives. The moves have raised concerns among military leaders, lawmakers, and defense experts about the politicization of the military and the loss of experienced leadership. Critics warn that these actions risk undermining the military's tradition of remaining apolitical and could have long-term consequences for morale and unity within the ranks.
