The first serious attempt to end the Iran war has failed. American and Iranian delegations spent roughly 21 hours negotiating in Islamabad, in the highest-level direct talks between the two countries since Iran’s 1979 revolution, but left without a final agreement. The talks followed a fragile two-week ceasefire announced earlier this week, yet the two sides remain divided over uranium enrichment, sanctions, Iran’s regional allies and, above all, control of the Strait of Hormuz. Iran has continued requiring ships to seek permission and reportedly pay for passage through the waterway, while Washington insists that international shipping must move freely. Donald Trump has now responded by ordering the US Navy to begin a blockade of Iranian ports from Monday, while allowing vessels travelling to non-Iranian ports to continue through Hormuz. The contradiction is striking: negotiations were supposed to convert a six-week war into a political settlement, yet their immediate failure has produced another coercive escalation. The deeper problem is that America and Iran are no longer negotiating only over nuclear technology or shipping. They are negotiating over who possesses the legitimate authority to set rules in a strategic space both increasingly believe they have already paid too much to surrender.
The Strait of Hormuz has become the clearest example of this disagreement. Iran increasingly treats control over passage as an attribute of sovereignty and a source of leverage acquired through its ability to disrupt the waterway. America treats freedom of navigation through an international energy artery as something no coastal state should be allowed to convert into a political toll system. Before the war, roughly a fifth of global oil and gas shipments passed through the strait, giving the dispute consequences far beyond the two belligerents. Both positions contain a recognisable principle. Sovereignty gives Iran rights within its territorial waters; international navigation prevents geography from giving one state unrestricted authority over commerce essential to everyone else. The difficulty arises because sovereignty cannot plausibly mean absolute control whenever a country’s geography intersects with a global public good. If it did, every strategically located state could transform international dependence into permanent political tribute.
America’s answer, however, creates its own philosophical problem. A naval blockade is one of the strongest forms of economic coercion available short of renewed large-scale bombing. Washington is effectively saying that Iran cannot use control of Hormuz to restrict other countries’ commerce while simultaneously asserting the right to restrict commerce entering or leaving Iran itself. The legal and strategic circumstances differ, but politically the symmetry is difficult to ignore: both sides are attempting to control economic access in order to change the other’s political behaviour. Each describes its own coercion as enforcement and the other’s as aggression. That is precisely why international rules matter. Without commonly accepted limits, freedom of navigation and sovereignty risk becoming principles states invoke selectively whenever each happens to strengthen their bargaining position.
The failed negotiations also reveal how far the bargaining agenda has expanded. American demands reportedly include ending Iranian uranium enrichment, dismantling major enrichment facilities, recovering highly enriched uranium, reopening Hormuz without tolls and ending support for groups including Hezbollah, Hamas and the Houthis. Each demand can be defended individually from an American security perspective. Collectively, however, they approach something much larger than a nuclear settlement. They require Iran to surrender several instruments through which it has historically attempted to compensate for conventional military inferiority. This creates the familiar problem of maximalist security: the stronger state defines security as removing the weaker state’s capacity to threaten it, while the weaker state experiences precisely that removal of capacity as making itself dangerously vulnerable.
This is why negotiations can fail even after both sides have suffered enough that peace appears economically rational. Iran may prefer sanctions relief and an end to bombing, yet still believe accepting every American demand would leave it unable to deter future intervention. Washington may prefer reopening Hormuz and ending an expensive war, yet still believe allowing Iran to preserve enrichment or regional military leverage simply reconstructs the original threat. Both therefore compare today’s compromise not only with today’s war but with the future bargaining position the compromise creates. A concession becomes expensive when leaders believe it makes the next confrontation harder to survive.
The ceasefire itself demonstrates another problem: parties can agree to stop shooting while disagreeing about what they agreed to stop. Iran has argued that continued Israeli operations against Hezbollah in Lebanon violate the wider understanding, while Washington has disputed that interpretation. Israel has continued strikes in Lebanon, and Prime Minister Benjamin Netanyahu has said there is no ceasefire there. This is not a minor drafting issue. Agreements collapse when parties possess different understandings of their scope because each can sincerely interpret the other’s behaviour as defection. Ambiguity can help negotiators reach an agreement initially by postponing difficult questions, but the same ambiguity can later destroy the agreement when those questions become operational.
The blockade now risks reproducing exactly that dynamic. Trump says the ceasefire is holding while simultaneously preparing a major new coercive measure against Iranian ports. Tehran may interpret the blockade as incompatible with meaningful de-escalation even if American weapons are not striking Iranian territory directly. Washington can respond that the measure merely prevents Iran exploiting the ceasefire to institutionalise control over Hormuz. Both interpretations can be internally coherent. The strategic danger emerges when each side’s supposedly defensive action changes the other’s incentives towards escalation.
Pakistan’s role in hosting the talks is worth noticing because it demonstrates how middle powers can acquire influence through diplomatic access rather than military scale. Islamabad maintains relationships with Iran, the United States, China and Gulf governments, giving it channels that few states possess simultaneously. Hosting the most important US-Iran negotiations in decades therefore reflects something increasingly common in a multipolar system: mediation does not always come from the world’s strongest states. It often comes from countries sufficiently connected to competing blocs that neither side regards them as completely captured by the other. Diplomatic usefulness becomes its own form of power.
India should draw the same lesson. New Delhi possesses relationships with Washington, Israel, Iran and Gulf governments while having an enormous economic interest in reopening Hormuz. India cannot determine the settlement, but it can support de-escalation, communicate across relationships and resist pressure to treat every conflict through rigid bloc politics. Strategic autonomy is most valuable when it produces options other states do not possess. Remaining outside alliances merely for the symbolism of independence would be strategically shallow; using independent relationships to preserve communication during crises gives autonomy practical value.
The blockade will now test whether coercion can succeed where negotiation failed. It may. Iran’s economy has already absorbed enormous damage, and restricting access to its ports can make continued resistance considerably more expensive. But coercion contains diminishing returns. Once a state believes the objective of pressure is not behavioural change but political submission, additional economic pain can strengthen rather than weaken resistance because surrender appears to threaten the state’s future autonomy. Governments and populations have repeatedly accepted material losses that external observers considered irrational when the alternative was perceived as humiliation or permanent subordination.
This is why the philosophical distinction between compromise and domination matters strategically. A settlement survives when both parties retain enough agency to prefer compliance voluntarily. A settlement produced only because one side has been rendered temporarily incapable of resisting may survive while that incapacity lasts, but it also creates incentives to rebuild power and revise the settlement later. The Treaty of Versailles remains the obvious historical warning against confusing an imposed settlement with a stable one. Peace requires more than ending resistance; it requires creating an equilibrium in which reopening the conflict no longer appears worth the cost.
The Islamabad talks failed because the United States and Iran still disagree about what that equilibrium should look like. Washington wants an Iran substantially less capable of threatening its neighbours and global shipping. Tehran wants enough independent capability that Washington cannot dictate Iranian policy whenever the balance of power favours America. Neither objective is inherently surprising. The difficulty is that maximising either one destroys much of the other.
The naval blockade may bring Iran back to negotiations under greater pressure. If it does, Washington will face the most important decision of the war: whether to use that leverage to obtain a limited, enforceable settlement or an increasingly comprehensive Iranian capitulation. The first may leave America with an adversary that remains unpleasant but constrained. The second promises greater immediate security but may require coercion indefinitely because Iran has fewer reasons to accept the resulting order as legitimate.
After six weeks of war, the military balance is no longer mysterious. America is stronger. The political question is much harder. A durable peace is not created when the stronger side finally proves it can impose its will; it is created when both sides conclude that living under agreed constraints is preferable to testing the balance of power again. Islamabad has shown that America and Iran are not there yet.
