The Strait of Hormuz is the world’s most important oil chokepoint. Roughly 21 million barrels of oil pass through it daily. It’s also one of the most militarized strips of water on the planet, where U.S. warships have been a constant presence for decades. For years, the game has been deterrence, signaling, sanctions, and very careful red lines.
On May 28, 2026, that careful architecture came apart.
The Strikes
The sequence of events, reconstructed from IRGC statements and U.S. defense briefings:
In the early hours of May 28 local time, U.S. military aircraft struck a location in the outskirts of Abbas Port — Iran’s primary port city on the Persian Gulf, and a significant military hub. The target was not specified by Pentagon officials in the initial readout, but three sources familiar with the operation described it as a retaliation strike.
Iran did not wait long to respond. Within hours, the Islamic Revolutionary Guard Corps announced it had struck the U.S. Air Force base that launched the aircraft. The statement was precise in its language, and deliberately theatrical in its tone: “This response is a serious warning to make the enemy understand that aggression will be met with retaliation, and if aggression recurs, our response will be more decisive. The aggressor must bear all consequences.”
Read that again. “More decisive.” That’s not the language of a group trying to de-escalate. That’s the language of someone leaving the door open for round two.
Trump’s Omani Ultimatum
While the strikes were happening, President Trump was at the White House delivering what multiple outlets are describing as an extraordinary cabinet meeting. His target: Oman.
Trump told assembled cabinet members that the Strait of Hormuz “belongs to nobody” and that if Oman — the country that shares responsibility for the strait’s eastern side — didn’t “behave,” it would get “blown up.” The exact quote, as reported: “If they don’t behave, they’re going to get blown out of the water.”
The context here is Oman’s unique geographic position. The country controls the Musandam Peninsula, which juts into the Strait of Hormuz and gives Oman joint practical oversight of one of the world’s most critical maritime passages. Oman has historically tried to remain neutral in U.S.-Iran tensions. It has also, quietly, served as a diplomatic backchannel for both sides.
Trump apparently decided neutrality is no longer acceptable.
The Cuban Angle
Here’s the subplot that didn’t get enough attention on May 28: the U.S. has a carrier strike group in the Caribbean — the USS Nimitz and its associated warships — that has been positioned there for months. According to Politico, the deployment is not routine. The Pentagon has pre-positioned forces for a potential strike on Cuba, with the Kearsarge amphibious assault ship standing by. U.S. drones and reconnaissance aircraft have been circling Cuba for months.
The Iran war is happening. The Cuban front is warming up. That’s not a coincidence — that’s a two-theater strategy, or at least the appearance of one.
What Makes This Different
Previous cycles of U.S.-Iran confrontation have been defined by proxy warfare: Yemen’s Houthis, Iraqi militia groups, Lebanese Hezbollah. The strikes on May 28 were not proxy strikes. They were not cyberattacks dressed up as something else. Two militaries with state structures, command chains, and identifiable assets looked at each other across a body of water and decided to hit each other directly.
That’s a qualitative change. Deterrence works until it doesn’t, and once it breaks, the question becomes how fast the escalator is moving.
Markets and the Strait
Oil markets reacted accordingly. Brent crude jumped on the news before partially retracing. The Strait of Hormuz is so critical to global supply that even a perceived threat of closure — not an actual closure — can move prices by several percentage points. Yesterday it moved.
The more unsettling dynamic is the feedback loop: higher oil prices benefit Iran, which exports at volume. They also put political pressure on the U.S. domestically. And they give both sides incentives to escalate rather than negotiate.
The Diplomatic Signal
Iran’s President Pezeshkian had, just days earlier, been making the rounds calling regional leaders and expressing readiness for a “comprehensive and fair” agreement. That messaging is now completely drowned out. When your IRGC is firing rockets at a U.S. base in the same week your president is doing diplomatic outreach, you have a coherence problem — and so does anyone trying to negotiate with you.
The U.S. position, as stated by Trump: the strait is international waters, open to all, and not subject to any country’s control. That’s a principled position and a strategically convenient one — it means any Iranian attempt to restrict traffic would be an act of aggression, and any Omani attempt to restrict traffic would be a betrayal.
The problem is that “international waters” is a legal concept that means very little when the missiles start flying.
The Strait of Hormuz has been a powder keg for 40 years. On May 28, someone lit a match and called it diplomacy.
