Iran this week published a map asserting control over more than 22,000 square kilometres of the Strait of Hormuz, including waters that fall within the territorial jurisdiction of Oman and the UAE. The claim came from a newly created “Persian Gulf Strait Authority,” which announced that all transit through the strait requires “coordination with and authorization” from Tehran. State-aligned media simultaneously published footage of what it described as a “punishment strike” on a commercial tanker in the waterway — footage BBC Verify matched to a Liberian-flagged vessel that reported being struck by unknown projectiles in early May. The US responded by telling commercial ships to disregard Iranian demands; the UAE described the claims as “fragments of dreams.” As of Thursday, Al Jazeera reported that the conflict has entered its 83rd day, that Iran has submitted a revised 14-point peace plan, and that Pakistan’s military chief is in Tehran attempting to mediate.
The received wisdom
The progressive-realist consensus on the Iran war is that it was an avoidable catastrophe — that the nuclear negotiations underway when the February attacks began were yielding progress, that Israel’s interests pushed Washington into a conflict that serves America’s only tangentially, and that the correct response now is diplomatic de-escalation at almost any cost. On this reading, Trump’s daily oscillation between threats and overtures is reckless but ultimately tolerable because it keeps the door to a deal nominally open. Iran’s Hormuz claim is understood as a desperate measure by a regime under existential military and economic pressure, and the appropriate response is to treat it as a bargaining chip rather than a declaration of intent. The argument has genuine force: the Strait of Hormuz carries roughly 20% of global oil supply, a prolonged closure would trigger a recession across the industrialised world, and the costs of miscalculation fall on populations who had no say in the conflict’s origin.
A different read
There is an older, grimmer literature on coercive diplomacy that the optimists tend to underweight. Thomas Schelling’s foundational work on deterrence and commitment — still the clearest framework for understanding how adversaries signal resolve — rests on a basic asymmetry: the party that can credibly commit to a course of action, regardless of costs, dominates the negotiation. Iran’s Hormuz theatrics are a textbook application of this principle. By creating a new institutional apparatus to administer the strait, publishing maps that encroach on allied waters, and demonstrating willingness to strike commercial shipping, Tehran is constructing a credible commitment structure. It is not saying “we will close the strait tomorrow.” It is saying: “We have built the machinery to do so, and we are prepared to use it incrementally.” That is a fundamentally different and more dangerous posture.
The Trump administration’s week-long rhetorical performance has done nothing to erode this commitment. Al Jazeera’s reconstruction of the president’s statements is striking in its incoherence: Sunday brought a “clock is ticking” ultimatum; Monday announced attacks were “on hold” at Gulf allies’ request; Tuesday revealed he had been “an hour away” from ordering strikes; Wednesday threatened “things that are a little bit nasty”; Thursday demanded Iran surrender its enriched uranium stockpile. No professional negotiator — and certainly no adversary’s intelligence service — could extract a consistent signal from this sequence. The problem is not that Trump is being tough. It is that he is being unpredictably both tough and accommodating in ways that Schelling’s framework predicts will produce the worst outcome: an adversary who is neither deterred nor incentivised to concede.
There is also a structural problem with the Gulf states’ role as diplomatic mediators. Qatar, Saudi Arabia, and the UAE asked Trump to hold off on strikes on Monday — and he complied. This is reported as a mark of the Gulf relationship’s value. It may be. But it also establishes a pattern: the Gulf states can constrain American military action by appealing to Trump’s transactional instincts. Iran’s strategists are not naive. They know that if they can keep the conflict below the threshold that would override Gulf diplomatic intervention, they retain room to manoeuvre. The 14-point peace plan Iran submitted Monday almost certainly contains terms no American president could accept — the BBC’s reporting notes that Iran has flatly rejected two of Washington’s stated prerequisites: surrender of its enriched uranium stockpile and acceptance of a Hormuz toll regime. Submitting an unacceptable plan while Gulf allies urge restraint is not diplomacy. It is a stall.
The historical parallel that comes to mind is not the JCPOA negotiations — a more orderly process under a president who actually wanted a deal — but the 1980s tanker war in the Persian Gulf. Ronald Reagan eventually decided that convoy protection and a credible willingness to engage Iranian forces was the only language that changed Iranian calculations. The lesson was not that military force solves everything; it is that diplomatic approaches without credible coercive backstops tend to produce negotiations that extend indefinitely while the adversary consolidates what it has already taken.
What to watch
- Whether Trump’s demand for Iran’s enriched uranium stockpile — a non-starter for Tehran — represents a genuine red line or a movable opener in the final negotiation phase. The answer will determine whether any agreement is reachable before the pause ends.
- The Walmart earnings warning, published simultaneously this week, noted that gas has risen to $4.56 per gallon since the war began. Consumer spending data for June will be the first genuine test of whether economic pain is changing American domestic politics around the conflict.
- US Central Command’s published figures — 94 ships redirected, 4 vessels disabled since the April 13 blockade began — represent operational tempo that cannot be maintained indefinitely without either escalation or negotiated resolution.
- Pakistan’s mediation effort in Tehran. Islamabad has incentives to prevent Iranian collapse that are distinct from the Gulf states’ interests; if Munir’s visit produces a counter-proposal different from the current 14 points, the diplomatic landscape may shift.
