Secretary of War Pete Hegseth told reporters Friday that any new Iranian attempt to lay mines in the Strait of Hormuz would constitute a direct violation of the cease-fire between the United States and Iran, and he declined to deny a leaked Pentagon assessment suggesting it could take up to six months to clear the waterway of mines already planted there.

The warning came one day after President Trump raised the stakes himself, declaring Thursday that the U.S. Navy would "shoot and kill" any Iranian vessel caught dropping additional mines in the strait. Together, the back-to-back statements from the president and his defense chief mark the clearest public line the administration has drawn on Iran's behavior since a cease-fire took hold.

But the six-month timeline, reported by the Washington Post, based on what Hegseth described as "another leak from a closed-door session", raises an uncomfortable question: even with a cease-fire in place, how long will one of the world's most important shipping lanes remain dangerous?

What Hegseth said, and what he wouldn't say

At a briefing in Washington, Hegseth addressed the leaked estimate head-on, without confirming or denying the six-month figure. He called it the product of a classified briefing that should never have reached the press.

"I saw that report. It was based on, again, another leak from a closed-door session, which was supposed to be classified. And apparently, allegedly, that was something that was said."

He then pivoted to a statement of capability rather than a commitment to a deadline. Hegseth told reporters the Pentagon would not "speculate on a timeline" but expressed confidence in the military's mine-clearing assets.

"We feel confident in our ability, in the correct period of time, to clear any mines that we identify, and would encourage other countries to be a part of such an effort as well, but we're tracking that very closely."

That phrasing, "the correct period of time", is doing a lot of diplomatic work. It acknowledges the problem without boxing the administration into a public deadline that Iran could exploit. For a Pentagon chief navigating both an active naval standoff and a fragile cease-fire, the hedge is deliberate.

The political pressure on Hegseth during the Iran conflict has been intense, with critics seizing on every statement. But his Friday remarks focused squarely on Iran's conduct, not Washington's internal feuds.

The strait: a chokepoint under strain

The Strait of Hormuz is not an abstraction. Between one-fifth and one-quarter of all seaborne oil in the world passes through it each year, bound mostly for Europe and Asia. When that chokepoint tightens, energy prices surge globally, and they already have.

Ship tracker Kpler reported that just eight vessels transited the strait on Thursday. None were Iranian-flagged, "shadow or sanctioned" ships. That number tells the story more plainly than any briefing: commercial traffic through the world's most important oil corridor has slowed to a trickle.

Hegseth acknowledged the damage. He described transit as "much more limited than anybody would like to see, and with more risk that people would like to see," blaming Iran's use of small, fast boats armed with weapons for the ongoing danger.

"That's because Iran is doing irresponsible things with small, fast boats, crafts, like I said, with weapons on them."

The United States has maintained a weeks-long naval blockade of the strait to counter what the administration describes as Iran's attempts to control shipping through the waterway. That blockade is now being reinforced. The USS Chief and USS Pioneer, both minesweepers, along with the USS Tulsa, have been ordered to the region to help clear the strait.

The Pentagon's broader deployment of Marines and preparation for ground operations in Iran provides the wider military context in which these mine-clearing efforts are taking place.

Underwater drones and allied support

The Wall Street Journal reported earlier this week that the U.S. military is deploying underwater drones as part of the mine-clearing operation, a sign the Pentagon is throwing advanced technology at a problem that has historically been slow, dangerous, and painstaking.

The effort is not American alone. U.S. allies in Europe have been weighing their own contributions. British military divers and other Royal Navy specialists are preparing to use autonomous systems for the mine-clearing mission, adding capability that the strait's sheer size demands.

That international dimension matters. Hegseth's public call for other countries to join the effort was not casual. Clearing a strait that serves global commerce should not fall solely on American sailors and American taxpayers. If European and Asian economies depend on Persian Gulf oil, their navies should share the risk.

Meanwhile, the Pentagon has also been drafting plans for ground forces in Iran, underscoring the scale of the military planning underway even as diplomatic channels remain open through the cease-fire.

The leak problem

Hegseth's frustration with the leaked six-month estimate was visible. He described it as coming from "a closed-door session, which was supposed to be classified." Whether the leak was designed to embarrass the administration, pressure allies into action, or simply reflected congressional carelessness, its effect is the same: it handed Iran a public data point about American limitations.

That is the real cost of Washington's leak culture. Every classified assessment that lands in a newspaper gives adversaries free intelligence. Iran now knows, or at least has reason to believe, that its mine-laying has created a problem the U.S. military may need half a year to solve. That knowledge changes Tehran's calculations, and not in America's favor.

Internal tensions at the Pentagon have drawn their own share of headlines. Reports of friction between Hegseth and Army Secretary Dan Driscoll have circulated, though Driscoll has said he will not resign. Disputed accounts of Pentagon meetings have also surfaced, with the Vatican itself calling one such report "completely untrue." The pattern is consistent: leaks create narratives that may or may not reflect reality, and adversaries benefit either way.

Iran's calculated recklessness

The administration's message is straightforward: Iran agreed to a cease-fire, and laying additional mines would break it. Hegseth was blunt on that point.

"If there's attempts to recklessly and irresponsibly lay more mines, we're going to deal with that. It's a violation of the cease-fire."

President Trump's Thursday warning, that the Navy would "shoot and kill" any Iranian boat caught in the act, removed any ambiguity about consequences. The combination of Hegseth's legal framing (cease-fire violation) and Trump's operational threat (lethal force) amounts to a two-part deterrent: diplomatic and kinetic.

Whether Iran takes the warning seriously depends on whether Tehran believes it will be enforced. The presence of minesweepers, underwater drones, and allied naval assets in the strait suggests the administration is not bluffing. But the leaked six-month estimate also suggests the cleanup, even without new mines, will be a long, grinding effort that keeps energy markets on edge and commercial shippers cautious.

Eight ships through the strait in a single day. That number should alarm every consumer who fills a gas tank, every manufacturer who depends on global supply chains, and every ally that imports Persian Gulf crude. Iran's mines are not just a military problem. They are an economic weapon aimed at the global economy, and every day they remain in the water is a day Tehran wins without firing a shot.

Clearing the Strait of Hormuz is the right mission. But it will take more than press conferences. It will take allies who show up, a Pentagon that stops leaking, and an adversary that understands the cease-fire is not optional.
