US and Iran trade strikes as ceasefire unravels over Strait of Hormuz

No reported US casualties or major damage to US facilities; Kuwaiti and Bahraini civilians advised to seek shelter during missile and drone attacks.
The administration of the Strait of Hormuz will never go back to the way it was
Iran's chief negotiator signaled the country's approach to managing the critical waterway would be fundamentally different from before the conflict.

Eleven days after the United States and Iran signed a ceasefire meant to stabilize one of the world's most consequential waterways, the agreement collapsed over a single drone strike on a commercial tanker in the Strait of Hormuz. Each side accused the other of breaking faith first, and within hours the exchange of strikes had spread to American military installations in Kuwait and Bahrain. What began as a fragile diplomatic architecture now stands as a reminder that agreements built on mutual suspicion carry within them the seeds of their own undoing — and that the Strait of Hormuz, through which a third of the world's seaborne energy passes, remains a place where local incidents carry global weight.

  • A ceasefire signed just eleven days ago between the US and Iran shattered when a drone struck a Panama-flagged tanker in the Strait of Hormuz, triggering immediate American airstrikes on ten Iranian military targets.
  • Iran retaliated within hours, launching ballistic missiles and drones at US air bases in Kuwait and Bahrain, claiming the American strikes — not the tanker attack — were the true ceasefire violation.
  • Civilians in Kuwait and Bahrain were told to seek shelter as air defense systems activated, making the abstract conflict suddenly immediate for people living near American military infrastructure.
  • Both governments are now issuing maximalist warnings: Iran threatened to halt all negotiations and deliver a 'crushing response' to any further strikes; Trump warned that Iran 'will no longer exist' if the US is forced to finish what it started.
  • Commercial shipping continues through the strait for now, but the ceasefire's collapse has revived the specter of a closure that, when it last occurred in February, sent global oil prices surging and disrupted shipments of food and fertilizer worldwide.

The ceasefire between the United States and Iran lasted eleven days. It ended on Saturday, June 28th, over a tanker in the Strait of Hormuz.

The sequence began when a drone struck the MT Kiku, a Panama-flagged vessel transiting the strait. The US military attributed the attack to Iran's Islamic Revolutionary Guard Corps and responded by striking ten Iranian military targets — hitting air defense systems, communications infrastructure, and drone storage facilities. US Central Command called it a necessary answer to continued aggression against commercial shipping.

Iran rejected that framing entirely. The IRGC said the US had attacked five coastal posts under false pretenses and that the tanker had been traveling an unauthorized route. Within hours, Iran launched ballistic missiles and drones at American infrastructure in Kuwait and Bahrain — targeting the Ali al-Salem air base and the Fifth Naval Fleet headquarters. A US official said there were no American casualties and no major damage, though Iran's claims of destruction went unverified.

What made the exchange significant was less the physical damage than what it revealed about the agreement itself. The two countries had signed a fourteen-point memorandum of understanding on June 17th, with Iran committing to safe, toll-free passage through the strait for sixty days. Now both sides were accusing the other of violating it first — each with its own narrative, neither willing to accept the other's.

The stakes were not abstract. The Strait of Hormuz carries roughly a third of the world's seaborne oil and liquefied natural gas. When Iran closed it in February, global energy prices spiked and essential goods were blocked. That risk was now returning. Iran's chief negotiator had already signaled the strait's management would never revert to its pre-war form, while Trump had publicly insisted Iran agreed to no tolls or charges of any kind. The gap between those positions had been widening before the first shot was fired.

In Kuwait and Bahrain, the response was immediate and visceral — air raid warnings, official instructions to seek shelter, defense systems brought online. Trump responded on Truth Social with language that transformed a military exchange into something larger, warning that Iran 'will no longer exist' if the US is forced to complete what it started. Iran's foreign ministry condemned the strikes as brutal, and the IRGC warned that any further aggression would bring a crushing response and end the negotiation process entirely.

Commercial vessels were still moving through the strait. But the ceasefire's architecture — always built on competing claims and mutual suspicion — had now been tested and found hollow. What remained was two militaries exchanging strikes, two governments issuing existential warnings, and a waterway whose stability had just become significantly harder to take for granted.

The ceasefire between the United States and Iran lasted eleven days. On Saturday, June 28th, it came apart over a tanker in one of the world's most critical shipping lanes.

The sequence began with a drone strike. A Panama-flagged vessel called the MT Kiku was hit in the Strait of Hormuz on Saturday. The US military said Iran's Islamic Revolutionary Guard Corps was responsible. In response, American fighter jets struck ten Iranian military targets across multiple locations near the strait—hitting equipment, communications systems, air defense installations, and drone storage facilities. US Central Command framed this as a necessary response to what it called "continued aggression" against commercial shipping.

Iran saw it differently. The IRGC said the US had attacked five coastal posts under false pretenses, and that the tanker had been operating on an unauthorized route. Within hours, Iran launched ballistic missiles and drones at what it described as eight key pieces of American infrastructure: the Ali al-Salem air base in Kuwait and the Fifth Naval Fleet headquarters in Port Salman, Bahrain. The IRGC claimed these strikes destroyed their targets. A US official told Reuters there were no American casualties and no major damage to US facilities in the region, though the claim of destruction went unverified.

What made this exchange significant was not the damage but the breakdown it represented. On June 17th, the two countries had signed a fourteen-point memorandum of understanding meant to end hostilities. Iran had committed to using its "best efforts" to ensure safe passage for commercial vessels through the strait for sixty days, with no charges. Now, less than two weeks later, both sides were accusing the other of violating that agreement. The US said Iran's drone attack on the MT Kiku was a ceasefire breach. Iran said the American strikes were the real violation. Each side had a narrative; neither could accept the other's.

The Strait of Hormuz is not an abstract strategic asset. It is the passage through which roughly a third of the world's seaborne oil and liquefied natural gas flows. When Iran had closed it in February, after US and Israeli strikes, global oil prices spiked and shipments of fertilizer and other essentials were blocked. The economic consequences rippled outward. Now, with the ceasefire unraveling, that risk was returning.

Iran's chief negotiator, Mohammed Bagher Ghalibaf, had signaled as recently as this week that the country's approach to managing the strait would be fundamentally different from before. "The administration of the Strait of Hormuz will never go back to the way it was before the war," he told state media. The US had been insisting that Iran had agreed to toll-free passage. Trump had posted on Truth Social that Iran confirmed there would be "no tolls, no insurance costs and no other charges of any kind." But the gap between what each side believed had been agreed to was widening.

In Kuwait and Bahrain, the immediate consequence was visceral. Air defense systems were activated. Kuwait's armed forces announced they were "confronting hostile missile and drone attacks" and told the public to follow security instructions. Bahrain's interior ministry urged citizens to remain calm and move to the nearest safe location. The strikes were real; the threat was immediate.

Trump responded with escalatory language. On Truth Social, he wrote that it was "very possible" Iran would "never learn." He added: "There may come a point when we are no longer able to be reasonable, and will be forced to militarily complete the job that we very successfully started. If that happens, the Islamic Republic of Iran will no longer exist!" The statement was unambiguous in its threat. What had been a contained military exchange now carried the weight of a presidential warning about the potential erasure of a nation-state.

Iran's foreign ministry condemned what it called the "brutal attacks" and accused the US of not valuing its commitments. The IRGC issued its own warning: "Any potential enemy aggression, under any pretext, even if the aggressions are against minor targets, as happened last night and tonight, will have a crushing response." It also threatened that further US violations would lead to "a complete halt to the process" of negotiation.

Commercial vessels continued to operate in the strait, according to US Central Command. But the fragility of the arrangement was now exposed. The ceasefire had been built on a foundation of mutual suspicion and competing claims about what constituted a violation. When the first real test came—a drone attack on a tanker, followed by an American response—the structure collapsed. What remained was two militaries trading strikes, two governments issuing warnings, and a critical waterway whose stability had just become significantly more uncertain.

There may come a point when we are no longer able to be reasonable, and will be forced to militarily complete the job. If that happens, the Islamic Republic of Iran will no longer exist.

Why did the ceasefire fail so quickly? Was there something fundamentally broken about the agreement from the start?

Model

The agreement was signed on June 17th, and by June 28th they were exchanging strikes. That's not a failure of implementation—it's a failure of shared understanding. Both sides signed the same document but read it differently. Iran thought it had the right to control passage through the strait. The US thought Iran had agreed to let ships through freely. When the first tanker used what Iran considered an unauthorized route, Iran saw enforcement of its own rules. The US saw aggression.

Inventor

But couldn't they have talked about it before escalating?

Model

They could have, but neither side trusted the other enough to give it a chance. The US struck immediately after the drone hit the tanker. Iran struck back within hours. There was no pause for negotiation, no attempt to clarify what had happened. The ceasefire was so thin that the first real incident shattered it.

Inventor

What does Trump's statement about Iran ceasing to exist actually mean? Is that a real threat?

Model

It's a statement of intent if negotiations collapse entirely. Trump is saying: if you keep attacking, we will finish what we started in February. Whether that means a full military campaign or something else, he's not specifying. But the message is clear—there's a line, and if Iran crosses it, the response will be total.

Inventor

How do ordinary people in Kuwait and Bahrain experience this?

Model

They're told to go to safe places while missiles and drones are in the air. The governments activate air defenses. It's the sound and fear of war without the war itself—yet. For them, the ceasefire breaking means their countries become targets again, even if they're not the primary combatants.

Inventor

Is there any way this gets back on track?

Model

Only if both sides decide the cost of escalation is higher than the cost of compromise. Right now, they're still in the phase where each strike feels justified and the other side's response feels like aggression. That usually has to get worse before it gets better.
