Washington claims Hormuz as territory in the same week Muscat and Tehran say they have agreed who routes the traffic

Trump posted the map on Truth Social on Tuesday morning with no accompanying text, according to Forbes, The Hill, The New Arab and The Media Line, which published a screenshot. A second post said there were “no talks or conversations going on, or scheduled, with the Islamic Republic of Iran,” that the Strait was “open and operating,” and that “all water mines have been removed or detonated”; The New Arab’s rendering of the same post has the blockade remaining fully in force. Those two claims sit awkwardly together, and both sit awkwardly against the traffic data: CNBC, citing the commercial tanker-tracking firm Kpler, reported that shipping through Hormuz appeared to grind to a halt on Sunday 16 August. The map followed remarks on 14 August to police officers in New York, where Trump said he would soon declare the strait a US territory, and an Oval Office exchange on Monday in which he said, “We control it with the blockade, and I like the idea of declaring it a territory,” and of Iran, “They can be a nuisance.”

Tehran’s reply was fast and specific. ABC’s live blog timestamps Iranian pushback at 08:32 EDT, some 43 minutes after the post went up at 07:49. Deputy Foreign Minister Kazem Gharibabadi wrote on X in Persian, per translations carried by Forbes, The Hill and Yahoo, that “the Strait of Hormuz has been Iranian, is Iranian, and will remain Iranian,” and that “this strait will only be closed and opened under Iran’s command.” He called the map a delusion that would be “corrected.” Hours before the post, Parliament Speaker Mohammad Bagher Ghalibaf had set out Iran’s price for reopening in four items, as reported by Forbes: lift the naval blockade of Iranian ports, release frozen assets, remove oil sanctions, and end military operations “on all fronts.” None of the four is a nuclear demand. The MoU that expired on Monday was supposed to deliver a nuclear and sanctions settlement in 60 days; both sides now describe the deadlock in terms of shipping management and money.

The consequential thread is Oman. On Monday, in an interview with Fox News' Trey Yingst, Trump said the United States would “bomb the s--- out of” Oman if it got in the way. The Hill notes that Yingst did not provide audio; CBS attributes the line to “Yingst’s recounting of his conversation with the president.” CNN, NBC, The Hill, CBS and Al Jazeera all carry it, and all carry the same unrecorded account. On Tuesday, a Washington Post report datelined Cairo said Trump made the threat because he is unhappy that Oman is close to a deal with Iran to manage ship traffic through the strait, sourced to two regional officials — the timestamp and photo credit suggest it is a single AP report rather than two confirmations. Iran’s foreign ministry spokesman Esmaeil Baghaei said on Monday the two countries had reached “an understanding” on the “map of the transit route,” without elaborating. Foreign Minister Abbas Araghchi said on 15 August that any such arrangement was possible only if a political solution were reached. Al Jazeera notes Hormuz runs partly through Omani territorial waters, that Oman has stayed neutral, and that this is Trump’s second threat to bomb it since a Cabinet meeting on 27 May.

Assessment: Read the map as a bid in a negotiation Washington is not in. The Iran–Oman track has produced no text, no Omani on-record confirmation and no third-party verification — only an Iranian announcement of an “understanding” that Araghchi has already made conditional on a settlement that does not exist. Distrust three things in equal measure: Trump’s claim that the strait is open, which Kpler’s traffic data contradicts; the Omani “deal”, which so far exists only in Iranian and semi-official Iranian statements; and the bomb-Oman quote, which reaches the public through a reporter’s recollection with no recording, however many outlets repeat it. What has actually changed is the currency of the dispute. Both Iran and Oman have floated fees on shipping; Iran’s stated war aim has been to force vessels onto routes and protocols it sets. The fight is over who collects and who certifies. A territorial claim is what you assert when the alternative is accepting someone else’s tollbooth.
