US Strikes Iran Again After Ceasefire—But This Time It's Different | Prof Jiang Xueqin

Let me tell you about a ship called the Ever Lovely. It's a cargo vessel, Singapore flagged, operated by Evergreen Marine, the same Taiwanese shipping giant you've probably seen on those enormous green containers stacked on trucks and trains across every port city in the world.

The Ever Lovely is not a warship. It's not carrying weapons. It's carrying goods. The kind of goods that fill the shelves of grocery stores. The kind that end up in factories, in hospitals, in homes. It is in every meaningful sense of the word a civilian vessel doing civilian work. And on Thursday, June 26th, 2026, somewhere in the Strait of Hormuz, about 7 and a half nautical miles southeast of the Omani port of Dahit, a drone hit it. The bridge windows shattered. The main engine kept running. The navigation equipment held. No one died. And the Ever Lovely, battered but intact, kept moving east, exiting the strait, heading toward open water.

Now, here's the thing. Within 24 hours of that drone strike, the United States military had launched retaliatory air strikes on Iranian territory, hitting missile and drone storage facilities, hitting coastal radar positions. Iran's IRGC said it struck back, targeting American military positions in the region without providing specifics. The United Nations paused its evacuation plan for more than 11,000 sailors stranded in the Persian Gulf since the war began in February. And the ceasefire that had been announced just 9 days earlier, the memorandum of understanding signed with considerable fanfare at the Palace of Versailles on June 17th, was suddenly looking extremely fragile. All of this triggered by one drone and one ship.

But if you think this is a story about a drone and a ship, you're missing everything that actually matters. Because what happened to the Ever Lovely is a symptom. It is a visible eruption of a conflict that has been building for decades. A conflict that goes all the way down to some of the most fundamental questions in international relations. Who controls the arteries of global trade? Who gets to define the rules of the sea? And what happens when a nation that just lost a war refuses to act like it lost?

Let's start from the beginning, not last Thursday, the actual beginning. The Strait of Hormuz is not just strategically important. It is by almost any measure the single most important maritime choke point on the planet. At its narrowest, it is roughly 30 km wide, barely the length of a small city from one shore to the other. On one side is Iran. On the other, Oman. And through that narrow corridor, before the war began this past February, approximately 20 million barrels of oil and petroleum products transited every single day. That's roughly 20% of the world's total oil supply passing through a gap you could almost throw a stone across. Not just oil, liquefied natural gas, fertilizer. About a third of the global fertilizer trade normally flows through this strait. Goods that feed people, that grow crops, that power cities across Asia, Europe, and beyond.

For Iran, this geography has always been leverage. The mullahs in Tehran understood something that sometimes gets lost in the noise of sanctions and nuclear negotiations. You don't need to win a war to cause catastrophic pain to your adversaries. You just need to threaten the right artery at the right moment. And the Strait of Hormuz is exactly that artery.

Now, the story that brought us to this point actually begins not in February 2026, but further back. In June 2025, there was what Trump called the 12-day war. Israeli strikes on Iranian nuclear facilities and military sites. A conflict that ended with a ceasefire, but resolved nothing fundamental. Iran's nuclear program was damaged. Key military commanders were killed, but the Islamic Republic survived. And surviving for the Iranian leadership was itself a kind of victory, or at least a basis from which to begin rebuilding the narrative.

Then came February 28th, 2026. The United States and Israel launched what the Pentagon codenamed Operation Epic Fury, a massive coordinated campaign targeting Iran's nuclear infrastructure, its missile programs, its military command centers. Ali Khamenei was killed in the strikes. The Supreme Leader, the man who had defined Iranian foreign policy for more than three decades, was gone. His son, Mojtaba, was elevated, widely seen as even more hardline, even more committed to the IRGC's vision of Iranian power.

And Iran's response, it did what Iran has always done when it cannot win conventionally. It went horizontal. It expanded the theater. It hit American military bases across the region. It targeted shipping in the Strait of Hormuz. It encouraged its proxies, the Houthis, Hezbollah, militias in Iraq to open new fronts. It turned a bilateral confrontation into a regional catastrophe. Oil prices spiked. Fertilizer shipments stopped. Thousands of sailors found themselves stranded in the Persian Gulf with no safe way out. The strait effectively closed.

And it worked. Not because Iran defeated America militarily. It didn't, not even close, but because the economic and political costs of sustained conflict became untenable. By early April, a ceasefire was in place. By June 14th, mediators announced the memorandum of understanding. By June 17th, Trump and Iranian President Pezeshkian had signed it. Trump at Versailles, a setting he presumably chose with great personal satisfaction. The MOU had 14 points. Among the most critical, Iran would allow toll-free passage through the Strait of Hormuz for 60 days. Mines would be cleared. A 60-day window would open for negotiations toward a final agreement. Iran would receive sanctions waivers and some frozen assets. The United States would proportionally lift its naval blockade.

The signing was presented as a historic breakthrough. And in one narrow sense, it was. Hostilities paused. Oil prices fell. Shipping began tentatively to resume. But here is what the fanfare obscured. The ceasefire paused the shooting. It did not resolve the underlying question. And the underlying question, the one that every diplomat in the room knew was unresolved, was this: Who actually controls the Strait of Hormuz?

Let me explain why that question is so consequential and why Iran's answer to it is so different from everyone else's. Under international law, specifically the United Nations Convention on the Law of the Sea (UNCLOS), all ships of all nations enjoy the right of transit passage through international straits used for international navigation. The Strait of Hormuz is unambiguously such a strait. Coastal states, meaning Iran and Oman, can regulate this passage in certain limited ways. They can set traffic separation schemes. They can require certain notifications, but they cannot require prior permission. They cannot charge tolls or fees. They cannot effectively close the strait to civilian vessels that pose no threat.

Iran, of course, never signed UNCLOS. But the legal principle of transit passage through international straits is considered customary international law, binding even on non-signatories, according to the overwhelming consensus of international legal scholarship. Iran's position is fundamentally different. Tehran argues, and this is important to understand, even if you don't accept it, that the Strait of Hormuz runs through its territorial waters and the territorial waters of Oman, and that as a coastal state, it has sovereign rights over navigation in those waters. The IRGC in particular has been pushing an even more expansive claim: that the only legitimate routes through the strait are those designated by Iran. That ships must contact the IRGC Navy on channel 16 before transiting, and that deviation from Iranian-approved routes is unacceptable and extremely dangerous.

Now, in peacetime, with American naval power dominant in the region, this claim was theoretical. Iran might assert it rhetorically, but enforcing it was another matter. The war changed that calculation. The closure of the strait demonstrated in the most concrete possible terms that Iran could actually follow through on the threat. The economic damage was real. The leverage was real. And so when the ceasefire came, Iran's negotiators walked into the room not as a defeated party making concessions from a position of weakness, but as a party that had demonstrated its capacity to inflict unbearable costs and was now prepared to monetize that leverage in the negotiations.

The question of routes, which specific paths through the strait are legitimate, is not a technical or bureaucratic dispute. It is the war by other means. It is the continuation of the strategic contest over who gets to exercise operational control of the world's most important waterway. When Oman, working with the International Maritime Organization, announced a new southern transit corridor last Wednesday, a route that hugs the Omani coastline, bypassing the northern corridor that runs through Iranian waters, the IRGC didn't simply object. It issued a stark warning: This route was established without Iran's knowledge or consent. It was unacceptable and extremely dangerous, and ships using it would face consequences.

And then they proved they meant it. The Ever Lovely was transiting the Omani corridor, the IMO-recommended route, when the drone hit it. This is the context that much of the reporting on this incident is missing. This is not a rogue action by a trigger-happy IRGC commander. This is the IRGC asserting with force a claim about who controls navigation in the Strait of Hormuz. The drone was not random. It was a message written in the language that international relations ultimately reduces to when words run out.

Now, let's talk about what the United States did and what it means. CENTCOM's response was swift. Within 24 hours, American aircraft struck Iranian missile and drone storage facilities and coastal radar positions. The statement called it a "powerful response to Iran's unwarranted aggression against commercial shipping." Vice President Vance posted on X: "Iran signed a ceasefire agreement. We have honored it. If they have disagreements about how the MOU is being applied, they can pick up the phone, but violence will be met with violence."

There's something almost theatrical about that statement. The image of JD Vance suggesting that the IRGC should pick up the phone, as if the Revolutionary Guards are a difficult client who needs to be walked through the terms of their contract, is striking in its confident simplicity. And to be fair to the administration, the American position is not unreasonable on the legal merits. The MOU stipulated toll-free passage. Iran attacking a ship on an IMO-approved corridor is a violation of both the letter and the spirit of what was signed.

But here's where I want to slow down, because the Iranian counternarrative is not simply propaganda that we can dismiss. The head of the Iranian Parliament's National Security Commission, Ebrahim Azizi, said on social media that "the United States had attacked Iran in the middle of negotiations once again." Iran's chief negotiator, Mohammad Bagher Ghalibaf, has stated publicly that "everyone should know that the administration of the Strait of Hormuz will never go back to the way it was before the war." And a senior Iranian deputy foreign minister said, in language that is easy to mock but important to take seriously: "Safe passage through the Strait of Hormuz with ambiguous arrangements, parallel routes, or decision-making outside of Iran's considerations as the coastal state cannot be guaranteed."

Read those statements carefully. What you're seeing is not simply defiance. What you're seeing is a party that believes the MOU, the document that supposedly ended the war, left the question of Iranian control over the Strait fundamentally unresolved. And they are not wrong to believe that, because Article 5 of the MOU addressed the strait, but it did so in deliberately ambiguous language. It said Iran and Oman would "discuss the future management of navigation," a formulation so vague that both sides could sign it while holding incompatible interpretations of what it meant. The Americans read "future management of navigation" as a transitional arrangement that would return the strait to its pre-war status: internationally governed, freely transited, with no tolls and no Iranian control over routes. The Iranians appear to have read the same language as a recognition that the post-war arrangement for the strait would be different, that Iran's enhanced role as what they call the "coastal state" would be formally acknowledged and institutionalized. These are not small differences that can be split at the negotiating table. They are incompatible visions of what the post-war order in the Persian Gulf looks like.

There's something else going on inside Iran that we need to understand, because the picture is more complicated than Iran decided to attack a ship. The Iranian political system, even after the death of Khamenei senior and the elevation of his hawkish son Mojtaba, is not monolithic. President Pezeshkian represents a faction that, by Iranian standards, is more pragmatic, more willing to accept a deal that provides economic relief in exchange for concessions on the nuclear program and implicitly on the strait. He was apparently clashing with the IRGC leadership during the war itself over strategy. The IRGC, on the other hand, has emerged from this war with its institutional power dramatically enhanced. The death of civilian and clerical leadership—Larijani was killed, the Supreme National Security Council building was destroyed—created a vacuum that the military has filled. "The IRGC is calling the shots," in the blunt assessment of Alireza Nader, one of the most respected Iran analysts working today. "There is no distinction between the IRGC and the state. They are effectively one and the same."

And the IRGC's view on the strait is clear. They have been issuing permits for the northern corridor, the one that runs through Iranian waters where they can monitor and control traffic. They have reportedly stopped issuing new permits even for that corridor, meaning only ships they already know and trust are getting through. The southern corridor, the Oman route, is the one that partially bypasses their control. And that, for the IRGC, is precisely what makes it unacceptable.

There were also hardliners in the Iranian parliament who seized on a written note attributed to the new Supreme Leader, Mojtaba Khamenei. A note in which he reportedly expressed doubts about the MOU framework before eventually endorsing it. Those hardliners have used that note to argue internally that the deal was made under duress, that the concessions on the strait go too far, and that Iran should retain its influence over the choke point as a permanent strategic asset. This internal Iranian politics is not separate from what happened to the Ever Lovely. It is inseparable from it.

Let me bring in the global dimension, because this conflict is not just about two countries. The Strait of Hormuz is vital for Iraq, Kuwait, Qatar, Saudi Arabia, and the UAE, all of whom depend on it for their oil and gas exports. Qatar's LNG exports pass through it. The UAE's oil revenues depend on it. Saudi Arabia, despite its pipeline alternatives, relies heavily on Hormuz for a significant portion of its energy exports. About a third of the world's fertilizer trade normally transits the strait. When that trade stops, food prices rise. Not immediately and not dramatically in rich countries, but in countries already on the margin, it matters enormously. This is a dimension of the conflict that rarely gets the attention it deserves. The people most harmed by the closure of the Strait of Hormuz are not Americans or Europeans. They are subsistence farmers in South Asia and sub-Saharan Africa who cannot afford food when global fertilizer supply is disrupted.

The 11,000 sailors stranded in the Persian Gulf waiting for the IMO's planned evacuation that was halted when the Ever Lovely was hit are from dozens of countries. Most of them are from the Philippines, Indonesia, India, and other lower-income nations where seafaring is one of the most reliable paths to a decent income. They have been stuck there since February, since the war began. Their families have been waiting. Their contracts have expired. They are hostages to a geopolitical chess match between Washington and Tehran in which no one is even pretending to prioritize their welfare.

As RBC Capital Markets analyst Helima Croft put it plainly in a note to clients: "Any end to this conflict that leaves Iran exercising operational control and influence over the strait will result in appreciably lower flows through the waterway, possibly permanently." Because even if a final deal is reached, ship owners and cargo companies will have absorbed the lesson of 2026. They will build redundancy into their routes. They will hedge. They will pay for alternatives. The strait may reopen formally and legally, but the trust required for normal commercial traffic to simply transit without anxiety—that trust has been broken, and it does not rebuild quickly. This is the long-term economic cost of this war that doesn't fit easily into the triumphalist narrative that some in the Trump administration have been projecting. "Iran is agreeing to everything I want," Trump said in late June. "We're winning by a lot, perhaps. But winning by a lot is compatible with leaving behind a strategic situation in the Gulf that is fundamentally more dangerous and economically disruptive than it was before the war began."

Now, I want to zoom out even further, because there is a pattern here that I think deserves to be named. This is not the first ceasefire that has run into trouble because of competing interpretations of what was agreed. It is not the first peace deal in the Middle East where the document signed was less significant than the gap between what the signatories believed they had committed to. Think about Oslo. Think about the Abraham Accords. Think about the JCPOA. In each case, the deal that was announced and celebrated was real in the sense that real concessions were made, real language was agreed, but the underlying tension that generated the conflict was only partially addressed. And partially addressed tensions have a way of reemerging, usually at the worst possible moment.

The MOU of June 17th is in this tradition. It paused the shooting. It created space for negotiation. It gave markets a temporary sense of relief. Oil fell towards $70 a barrel, a dramatic drop from the wartime highs. Trump could go to Versailles and present a photograph of himself and Pezeshkian signing a document, which is genuinely valuable political currency. But the question of who controls the Strait of Hormuz, who designates the routes, who collects the information on transiting vessels, who has the authority to turn a ship back—that question was not answered. It was deliberately deferred. And the IRGC, which was not willing to wait 60 days to see how the negotiations unfolded, answered it their own way with a drone aimed at the bridge of a Taiwanese, Singapore-flagged cargo ship on an Omani-approved route 7 and a half nautical miles from the Omani coast.

What happens next? I want to be honest about the limits of what any analyst can tell you here, because the situation is genuinely fluid and the variables are many. There are a few possible trajectories.

The first is escalation. The American retaliatory strikes provoke further Iranian retaliation. The IRGC, which said explicitly that "if the aggression is repeated, our response will be more extensive," follows through. We enter a cycle of tit-for-tat strikes. The ceasefire collapses in practice, even if neither side formally withdraws from the MOU, and the 60-day negotiation window closes without a final deal. This is the worst case, and it is not the most likely outcome, but it is not impossible.

The second is managed fragility. Both sides absorb the current round of strikes, pull back from the edge, and the MOU limps forward. The evacuation of sailors resumes. Some commercial traffic flows through the strait, but on two separate, competing corridors with no consensus on which is legitimate, with ship owners forced to make their own risk assessments about which route to take and which naval authority to contact. This is the situation that Lloyd's List, the shipping industry publication, described as a "confused two-tier system": a northern route controlled by the IRGC, a southern route coordinated by Oman and the United States, and the pre-war routes rendered unusable by mines that haven't been cleared yet. This is messy and expensive and dangerous, but it is, in a paradoxical way, functional enough to prevent another outright closure.

The third is breakthrough. The establishment of a USCENTCOM to IRGC Navy communication line, which was reportedly agreed on Friday, the same day the American strikes were conducted, suggests that both sides are simultaneously willing to exchange fire and talk. That's not as contradictory as it sounds. In crisis management theory, this is actually a reasonably sophisticated response. You signal resolve with the strike. You create a channel for de-escalation with the hotline, and you keep the negotiations alive. The 60-day clock on the MOU is still running. A final agreement on the nuclear file and on the permanent status of the strait is still theoretically achievable. If it happens, it would be genuinely significant.

But I want to be clear about something. Even a final deal, even a comprehensive agreement that addresses the nuclear program, defines the legal status of the strait, and normalizes relations, does not erase what has happened. The genie is out of the bottle. Iran has demonstrated, in ways that are now recorded in every shipping company's risk model, every insurance underwriter's actuarial table, every energy minister's contingency planning document, that it can close the Strait of Hormuz. It can do it again. And the credibility of that threat does not disappear because a document was signed in Geneva or Muscat or wherever the final deal lands.

I want to close with something that I think gets too little attention in the way this conflict is usually covered. The narrative frame that dominates in Washington and in the Western media is a straightforward one: America and its allies represent freedom of navigation, international law, the rules-based order. Iran represents revisionism, aggression, the attempt to extort the world through control of a choke point. In this frame, the drone attack on the Ever Lovely is simply more Iranian lawlessness to be deterred and punished.

That frame is not entirely wrong. Iran did attack a civilian vessel on an IMO-approved route. That is a violation of the ceasefire. It is a violation of international maritime norms. It is indefensible under any interpretation of the law of the sea. But the frame is also incomplete in ways that matter if you want to understand what's actually happening, rather than just who to cheer for. The Strait of Hormuz physically runs through Iranian and Omani territorial waters. Iran is legally and geographically a coastal state with legitimate interests in how the strait is managed. The pre-war arrangement, where traffic flowed on internationally designated routes without Iranian permission, was not the natural order of things given to us from the heavens. It was an arrangement sustained by American naval dominance, by an implicit deterrent. Any Iranian attempt to restrict passage would be met with overwhelming force. That deterrent is what the war tested. And the war revealed that the deterrent, while real, had costs that American domestic politics were not fully prepared to absorb.

Iran did not win the 2026 war. Let me be unambiguous about that. Its nuclear program was devastated. Its Supreme Leader was killed. Its military infrastructure was significantly degraded. Its economy, already strained by decades of sanctions, was further crippled. By any conventional military accounting, Iran lost badly. But Iran extracted leverage from the war that it did not have before. The strait is genuinely contested in a way it was not before February 2026. That leverage is real.

And the question of how to manage a world in which a country that has been militarily defeated nonetheless retains significant strategic leverage over a vital artery of global trade—that is a question that American foreign policy has not yet fully answered. J.D. Vance said, "Violence will be met with violence." That's a sentence. It's not a strategy. The strategy, if one exists, needs to answer the harder question: How do you get to a stable, sustainable arrangement in the Strait of Hormuz that is consistent with international law, that prevents Iran from monetizing its geographic position, that doesn't require permanent American military patrols in an enclosed sea, and that the IRGC, for all its belligerence, can live with? That question is what the 60-day negotiating window is supposed to answer. As of this weekend, that window has been cracked open by a drone and is leaking badly. Whether the diplomats can seal it before it blows out completely—that is what we'll be watching in the days and weeks ahead.

The Ever Lovely has sailed on, its cargo intact, its crew safe. Bridge windows broken, but moving. There's a metaphor in there somewhere if you're looking for one. The question is whether the architects of this fragile piece
