The Chairman of the Joint Chiefs of Staff, Gen. Dan Caine, is the highest-ranking military officer in the United States. He advises. He recommends. He cannot order the president to do anything. According to CNN and the Wall Street Journal, Caine told the president that munitions stockpiles were running low and that the available target list was becoming meager, and that continuing strikes at the current pace risked leaving the United States short of the interceptors it would need for a future conflict with a larger adversary. But it was the president’s decision alone how much weight to put on those recommendations.
Understanding that single fact explains more about why the Iran strikes paused, and resumed, than anything said publicly in Washington this week.
The chain of command runs from the president to the secretary of defense to the combatant commanders. Gen. Caine, despite his prominence in public briefings, sits outside that direct operational chain. His role is advisory. He transmits lawful orders. He does not command combat forces.
That distinction matters because it means the most senior uniformed military voice in any White House meeting is offering a recommendation, not issuing an order. The president can take it or leave it.
Elizabeth Dent, a senior fellow at the Washington Institute for Near East Policy who served as the Pentagon’s director for the Gulf and Arabian Peninsula at the Office of the Secretary of Defense, explained the dynamic to MBN. “The president always has a wide range of options in front of him,” she said. “CENTCOM doesn’t come with just one operational recommendation. They’re going to come with multiple options. And so the president will make the determination about which way he wants to go based on the recommendations of his most senior advisers. But as we know with President Trump, sometimes he can go against the word of a lot of his advisers and may end up choosing a path that is not the recommended way forward.”
Before a Strike Is Authorized
Before any major military operation reaches the president’s desk, it moves through a layered interagency review. Regional policy committees conduct intelligence assessments and legal evaluations. Proposals advance to the Deputies Committee, deputy secretaries of cabinet departments, and the vice chairman of the Joint Chiefs. Then to the Principals Committee: the secretaries of defense and state, the director of national intelligence, the CIA director, the attorney general, and the chairman of the Joint Chiefs, meeting under the national security adviser. The president receives a refined set of options, not a single recommendation.
Every target in that package has been through what the military calls the Collateral Damage Estimation Methodology, a standardized process governed by Chairman of the Joint Chiefs of Staff Instruction 3160.01 that requires analysts to calculate blast radius, structural fragmentation, and non-combatant casualty risk before any strike is authorized. If calculated casualties exceed the threshold set by the president or secretary of defense, authorization automatically elevates up the chain.
The process is strict by design. It operates on the assumption that decisions flow through the same architecture at every level.
When the Target List Runs Out
CNN and the New York Times reported that the pre-approved target list had been “largely exhausted” after 13 nights of strikes, raising immediate questions. Brent Sadler, a former Pentagon official, told Fox Business that the munitions shortage problem has been known since 2012, calling it an ongoing structural issue that predates the current conflict. “This is a critical issue for potential major combat operations,” Sadler said, stressing the need for continued vigilance despite current inventories. What does that actually mean in military terms?
Dent was precise. “It could mean that some of the targeting datasets are out of date,” she said. “It could mean that we just don’t have enough intelligence or information from either our own sources or regional partners in order to develop additional targets. But I don’t think that there’s any scenario in which the target list has been completely utilized.”
She added that new targets are always in development. “It just means that a lot of the known places for the ballistic missile sites or cruise missile sites or drone facilities have already been targeted. But as we have seen, the Iranians still maintain those capabilities. And therefore more targets will be developed.”
The distinction is important. An exhausted pre-approved target list does not mean no targets exist. It means the intelligence underlying the existing list has been acted upon, and new intelligence needs to be developed and validated before additional strikes can be legally and operationally authorized.
The Stockpile Question
The interceptor concern was not abstract. Analysts Mark Cancian and Chris Park at the Center for Strategic and International Studies in Washington estimated global Patriot inventories had fallen below 1,000 missiles, with THAAD inventories at approximately 250 units.
Dent addressed the stockpile question directly. “Our munition stockpile, interceptor stockpile, defensive systems, all of those things are concerns that the United States has to take into consideration as it continues on this campaign,” she said. “There is a lot of reporting in the press about how munition stockpiles are very low for the United States. If they’re low for the United States, that means that they are very likely low for a lot of our regional partners who rely upon these interceptors to ensure that missiles and drones cannot harm their civilians or their civilian infrastructure.”
She added: “I don’t think that we have any clear indication of what exactly that degradation of the stockpile actually looks like.”
The Pentagon’s own procurement actions reflected those concerns. Concurrently with the pause, the Department of Defense announced two seven-year framework agreements with Lockheed Martin and L3Harris to expand production capacity for PAC-3 MSE and THAAD interceptor components.
When asked whether diplomacy and stockpile concerns could both have contributed to the pause simultaneously, Dent did not dismiss either factor. “It could certainly be real,” she said. “I don’t think that we’ve seen anything public to indicate that that is the case. But certainly we’ve seen backchannel discussions, at least publicly reported, with the United Arab Emirates and Iran, with Pakistan and Iran, Qatar and Iran, Oman and Iran. So hopefully at some point those discussions will lead to some sort of diplomatic opening.”
What to Watch
Asked what indicators to watch over the coming days, Dent was clear. “I think it’ll be really interesting for us to see whether or not the Iranians launch a counterstrike to the strikes that the United States waged last night,” she said. “We will have to see who they target, which of the regional partners they target, whether it is explicitly military infrastructure.”
She did not predict a diplomatic opening. “I don’t expect this to end anytime soon. And unfortunately, I don’t see a specific diplomatic opening. But I will be looking for a country that is willing and able to sort of halt the escalatory steps that we are currently spiraling on. Now, whether that’s the Iranians or whether it’s the Americans, I think remains to be seen.”
