Hesseth Fires Pentagon Chief Military Strategist Pentagon chief Pete Hesseth has fired Lt. Gen. Brett Silvia, who served as a strategic planner at the Joint Chiefs of Staff. The exact reasons for this decision are not disclosed, but The Atlantic, citing its sources within the department, reports the resignation. Sylvia led the Strategy, Planning and Policy Division (J5), responsible for developing military scenarios and synchronizing the actions of military commanders with political leaders. The resignation of the expert occurred against the background of Trump's White House exploring options for new military action against Iran; According to the publication, his departure could complicate this process. According to sources, Hesseth lost support and fell out with Deputy Defense Secretary Elbridge Colby, who oversees the political sphere. No official statement was made. The general's profile disappeared from the committee's website, but the name of his replacement was not published. Sylvia served for 32 years, previously leading the 101st Airborne Division. He was the second J5 chief to resign under Gest: the previous chief, Joseph McGee, left the post in October of last year. According to calculations by the "Atlantic", at least 26 admirals and generals left the Pentagon during Hessett's leadership.
