US Defense Secretary Pete Hegseth has fired Army Lieutenant General Brett Sylvia, director of the Strategy, Plans and Policy Directorate at the Joint Chiefs of Staff, for alleged severe misconduct. The Pentagon states Sylvia was under investigation for leaking classified information regarding the Iran war and the war between Russia and Ukraine. The investigation is ongoing and has been referred to the Department of Justice. Sylvia reportedly failed three polygraph tests concerning the leaks and was accused of putting national security at risk. This marks the second ousting from the J5 post under Hegseth, and comes amid reports that the US had warned allies of possible renewed strikes against Iran, and as former President Trump has repeatedly floated new military operations against Iran.
