The Pentagon is seething over a Washington Post report that top military leaders recently warned Defense Secretary Pete Hegseth against extending large-scale Iran war operations.

People familiar with a classified assessment prepared for Hegseth told the Post that several combatant commanders have advised the Defense chief that prolonging operations against Iran is unsustainable and risks weakening the U.S.’s ability to address threats elsewhere, including on U.S. soil.

The warnings appear in the Aug. 14 edition of the Secretary of Defense Orders Book (SDOB), detailed by the heads of the Army, Navy and Air Force, and the four-star commanders overseeing U.S. operations throughout Europe, Asia and Latin America, the Post reported Sunday.
