The morning air near a waterfront can be sharp with salt, and today it felt like the kind of day ships hate—where the rules suddenly change. Across capitals, the same question kept coming back: who gets to move, and who gets stopped.
Donald Trump has said the US Navy will blockade the Hormuz strait and also prohibit every vessel in international waters that had paid a toll to Iran. US Central Command later said it would begin a blockade of all Iranian Gulf ports and coastal areas on Monday at 10am ET (5.30pm in Iran and 1400 GMT), effectively seizing control of maritime traffic in the strait of Hormuz.
The measure, according to Misryoum newsroom reporting, will be enforced broadly. The US military sent a note to seafarers warning that the blockade will apply to all vessel traffic, regardless of flag. It says any vessel entering or departing the blockaded area without authorization is subject to interception, diversion, and capture, while also stating that the blockade will not impede neutral transit passage through the strait of Hormuz to or from non-Iranian destinations. It’s a tight line—permission for some routes, restriction for others—and crews are already being told to treat it as such.
Within Europe, the language turned from operational to political. UK prime minister Keir Starmer insisted the UK does not support the blockade and said, bluntly, “we are not getting dragged into the war”. In separate comments, Ursula von der Leyen said restoration of freedom of navigation in the strait of Hormuz is of “paramount” importance, adding pressure on governments to avoid an open-ended escalation. Starmer also argued the UK isn’t responsible for the rising energy costs, blaming Iran for restricting traffic through the Gulf in breach of international law—while saying UK efforts are focused on diplomacy and keeping the strait fully open.
The dispute is not only about shipping lanes. Oil prices rose early on after the blockade announcement: US crude oil rose 8% to $104.24 a barrel and Brent crude rose 7% to $102.29. Australia’s share market dropped sharply on Monday morning. Iran’s parliamentary speaker Mohammad Bagher Ghalibaf mocked the move on X, posting: “Enjoy the current pump figures. With the so-called ‘blockade’, Soon you’ll be nostalgic for $4–$5 gas.” Earlier, he said Trump’s threats would have no effect on the Iranian nation, warning “If you fight, we will fight … We will not bow to any threats.”
And while ships wait for orders, a very different kind of confrontation is playing out in public. Trump lashed out on social media at Pope Leo XIV after the pope had called for an end to war without directly naming the Iran conflict. Trump posted a more than 300-word diatribe accusing the pope of catering to the “Radical Left” and being “terrible” for foreign policy. Monday, the pope told reporters he has “no intention to debate” with Trump over Iran—but then added that he will continue to “speak out loudly against war,” promote peace, dialogue, and multilateral relationships, and look for just solutions. It’s an odd choreography: official statements about maritime control on one side, and church language about war and peace on the other.
Still, the situation on the ground keeps bleeding through the headlines. Misryoum newsroom reporting also notes that the Israeli military said on Monday it has begun targeted ground operations in the Bint Jbeil area in southern Lebanon, while Lebanon’s state-run National News Agency said nine people were killed and 13 wounded in an Israeli attack on the town of Tefahta in southern Lebanon on Sunday. Whether leaders can separate doctrine, deterrence, and battlefield realities is a different question—and maybe not one anyone is ready to answer cleanly today.
