Joint Chiefs of Staff

The Joint Chiefs of Staff is the United States military's top advisory body, bringing together the chairman, vice chairman and the service chiefs of the Army, Navy, Air Force, Marine Corps and Space Force. Its chairman serves as the President's senior military adviser, though operational command of forces runs through the President and Secretary of Defense to the combatant commanders, not through the Joint Chiefs itself.

During the Iran campaign the chairmanship, held by General Dan Caine, has functioned as an internal check on the pace of bombing, flagging munitions stockpile levels and escalation risk to the President. That advisory role sits alongside, and sometimes in tension with, political pressure from the White House and congressional voices to sustain or intensify the campaign.

The body's influence is advisory rather than decisive: its warnings can slow a campaign but cannot, on their own, halt or restart one, since those decisions remain with the President and the operational chain of command.
