President Trump’s blunt warning to Oman over the Strait of Hormuz has opened a tense chapter in a long-standing U.S.-Oman relationship, testing Muscat’s role as a quiet mediator with Tehran and exposing a serious policy disagreement about who controls crucial shipping lanes. The exchange centers on reported talks about tolls or joint management of the strait that could grant Iran leverage over one of the world’s energy lifelines, provoking a sharp reaction from the administration. That clash pulls into focus U.S. priorities: freedom of navigation, deterrence, and the utility of intermediaries who can talk to adversaries without undermining American security.
The president did not mince words in a recent Cabinet meeting where he insisted on keeping Hormuz open and free. “The strait’s gotta be open to everybody,” he said during a Cabinet meeting Wednesday. “It’s international waters. Nobody’s going to control it. We’re going to watch over it. We’ll watch over it, but nobody’s going to control it. That’s part of the negotiation that we have. They would like to control it; nobody’s going to control it. It’s international waters. And Oman will behave just like everybody else, or we’ll have to blow ’em up. They understand that. They’ll be fine.”
That language shocked some diplomatic watchers, but it reflects a Republican instinct: clear red lines and the willingness to back them. For decades, Oman has been useful precisely because it kept channels open to Iran when most Gulf partners would not. “Oman’s role as the Switzerland of the Middle East has advanced U.S. interests,” April Alley, a senior fellow at The Washington Institute, told Fox News Digital.
Oman’s backchannel status helped pave the way for past nuclear talks and other quiet diplomacy, but the current dispute shows the limits of goodwill when strategic chokepoints are involved. “They have facilitated numerous rounds of talks between U.S. and Iranians,” she said. “They were also able to broker a truce between the US and the Houthis in the Red Sea. Their neutrality allows them to be quiet facilitators when adversaries are ready to talk.”
Still, the administration is worried that discussions about tolls, fees, or joint management of the Strait of Hormuz could hand Iran a tool to harass shipping or extract payments. “Oman has long played an important role as a quiet mediator, acting as a go-between for the United States and Iran in various negotiations including for the Obama-era JCPOA and more recently with the Trump administration and its efforts to negotiate with Iran prior to the 12-day war in June 2025,” she said. That kind of stewardship is valuable only so long as it does not compromise freedom of navigation.
Experts see the president’s words as both a posture and a policy signal. “I think it was both,” Alley said when asked whether the remarks were simply an unusual threat directed at a longtime U.S. partner or reflected deeper concerns. “Beyond the shock value, I think it reflects clear frustration on the part of the administration with the Omani approach to the Strait,” she said. “The President is signaling that Oman has gone too far in discussions with Iran on options for opening the Strait that could give Iran administrative control and interfere with freedom of navigation.”
The core American worry is straightforward: once a great power sets a precedent for charging tolls or imposing administrative control, other actors will mimic it and freedom of the seas will erode. “The administration is right to be concerned about tolls, fees, or joint management of the Strait,” Alley said. “All of these things are a recipe for Iran interfering with freedom of navigation in the long term and they could set a dangerous precedent for other international waterways.”
That domino fear has specific regional echoes. “I could see the Houthis trying for the same in the Bab al-Mandeb,” she said. If Tehran can monetize or regulate vital routes, proxy groups and opportunistic states could try the same trick elsewhere, raising insurance costs and threatening global energy flows.
Critics of Oman argue that its neutral posture sometimes crosses into troubling tolerance of bad actors and shady logistics. “Oman often acts as Qatar-lite,” Rubin told Fox News Digital. “They like to mediate but, in the past at least, they appear to have turned blind eyes to terror finance and weapons smuggling.” Skeptics worry Muscat’s bridging role can become a blind spot for enforcement if not carefully managed.
Still, the bilateral relationship is deep and durable, and Americans benefit from keeping lines open while standing firm on core principles. “For a century and a half, Oman has been a close partner to the United States,” he said. The task ahead for any Republican administration is to defend navigation rights and deterrence while using partners like Oman smartly, not naively, to resolve conflicts on terms that protect American interests.
