Trump Threatens to Claim the Strait of Hormuz as US Territory After War with Iran
On Friday, August 14, 2026, Donald Trump threatened to designate the Strait of Hormuz as "a territory of the United States" once the ongoing war with Iran concludes, escalating an already fraught standoff over the critical waterway that has been effectively closed since the US and Israel launched military operations against Iran in February 2026.
Speaking at a police academy on Long Island, New York, Trump said: "After we finish defeating Iran, which is being very badly defeated, pretty soon I'll be declaring the Hormuz strait a territory of the United States. Essentially, that's what it is. We have the blockade. No ships get through unless we want them to." (The Guardian)
The strait connects the Persian Gulf with the Gulf of Oman and serves as a crucial chokepoint — a narrow passage that shipping must pass through — for global trade. Roughly a fifth of the world's seaborne oil supplies typically transit through it. Its near-total closure since the outbreak of hostilities has sent fuel prices sharply higher, a cost Trump asked Americans to bear. He said those paying more for gasoline should remember they are doing so to prevent Iran, which he called the No 1 state sponsor of terror, from obtaining a nuclear weapon. (Reuters; The Guardian)
The remarks come as peace negotiations remain deadlocked. Iran has refused to reopen the strait without significant US concessions. As of August 8, 2026, Tehran stated it would not reopen the waterway unless Washington "corrects its behavior," "completely compensate[s]" Iran for war damage, lifts sanctions (government-imposed economic restrictions designed to pressure a country into changing its behavior), and "unconditionally" releases frozen assets. The demand list sets a high bar for any diplomatic breakthrough and effectively positions the strait's status as leverage in broader negotiations. (The Guardian)
Iran's deputy foreign minister, Kazem Gharibabadi, responded directly on X, stating that Tehran would not be intimidated by US threats and that the Strait of Hormuz would only be opened or closed under Iran's authority. The rebuttal signals that Iran views control of the waterway as a sovereign prerogative — a right exercised by an independent nation over its own territory — not a bargaining chip to be ceded under military pressure.

Trump's Friday speech builds on rhetoric from earlier in the week, when he claimed on Truth Social that the US had "total control" over the strait and added, "I think we will keep it." The progression from asserting de facto control to proposing a formal territorial designation marks a rhetorical escalation, though the legal and operational mechanics of such a declaration remain unspecified. (The Guardian)
Secretary of State Marco Rubio has separately indicated that Iran's proposal to impose a toll on the strait would render any negotiated settlement "unfeasible," as reported by the Associated Press in May 2026. That position predates the latest escalation but establishes the State Department's baseline: Iran's conditions for managing the waterway are incompatible with US terms. (AP News)
The broader context here is a six-month conflict that has upended one of the world's most consequential shipping lanes, with no diplomatic off-ramp in sight. Both sides have staked out maximalist positions on the strait's future: Trump asserts unilateral US control; Iran demands war reparations, sanctions relief, and asset releases as preconditions for even reopening transit. The gap between these positions is not narrowing, and each public exchange appears to harden rather than soften the respective red lines.
For energy markets, the implications are direct. With roughly 20 percent of seaborne global oil supply normally routed through Hormuz, the continued closure exerts upward pressure on prices that no rhetorical escalation from either side is likely to relieve. Trump's framing of higher gasoline costs as a necessary sacrifice for nonproliferation objectives — the effort to stop the spread of nuclear weapons — signals an administration prepared to absorb domestic political risk from fuel inflation rather than accelerate a deal on Iran's terms.
Whether a unilateral US territorial claim over an international waterway could withstand legal challenge under the United Nations Convention on the Law of the Sea (UNCLOS) is a question Trump's speech did not address. The US is not a party to UNCLOS, though it recognizes many of its provisions as customary international law. Iran, Oman, and other Gulf states have overlapping jurisdictional claims over the strait, and any assertion of US sovereignty would likely draw objections not only from Tehran but from Gulf monarchies that rely on the waterway for their own energy exports. The legal architecture governing straits used for international navigation grants all states transit passage rights, a principle that a US territorial designation would directly contravene.
The question now is whether this rhetoric hardens into policy or remains a pressure tactic. Trump conditioned the declaration on first "finishing defeating Iran," which ties the strait's status to a battlefield outcome that has not yet been achieved. Until that condition is met, the threat functions as a signal of intent rather than an actionable directive. But the cumulative effect of successive escalatory statements, from "total control" to "territory of the United States," suggests a trajectory in which the administration is preparing domestic and international audiences for a durable American presence at the chokepoint, regardless of how or when the war ends.
