Donald Trump has given Iran until Tuesday evening to reopen the Strait of Hormuz, threatening strikes against Iranian power stations and bridges if Tehran refuses. The ultimatum comes more than a month after the United States and Israel began their war against Iran, during which 13 American service members have been killed, Iran has effectively blocked one of the world’s most important oil routes and average US petrol prices have risen to about $4.11 a gallon, from below $3 before the war. Trump says negotiations remain possible and has suggested an agreement could still emerge before the deadline, but his rhetoric has become substantially more threatening, including warnings of attacks on civilian infrastructure if Iran continues restricting the strait. The immediate dispute concerns freedom of navigation. The more interesting strategic problem is that the war has created a strange reversal of power: America can destroy Iranian infrastructure almost at will, yet Iran can still influence the economic conditions under which America decides how long it is willing to continue fighting.
This distinction between destructive power and bargaining power is becoming increasingly important. In purely military terms, there is no serious comparison between the United States and Iran. Washington possesses vastly greater air power, intelligence, naval capacity and economic resources. Yet political power is relational: what matters is not simply how much capability a state possesses, but whether it can affect something another actor values. Iran’s position beside Hormuz gives it precisely such leverage. By restricting a narrow waterway through which a large share of internationally traded energy normally passes, Tehran can increase fuel prices for American voters, production costs for European firms and import bills across Asia. Iran cannot force America to surrender militarily, but it can make continuation of the war progressively more expensive politically. A weaker actor therefore does not need symmetrical strength if it possesses an asymmetrical vulnerability belonging to the stronger actor.
Trump’s threatened response raises a more difficult question about the limits of coercion. Bridges and electricity systems can have legitimate military uses, but they are also infrastructure on which civilians depend. International humanitarian law distinguishes military objectives from civilian objects and requires proportionality in attacks expected to harm civilians. The strategic problem exists even before the legal one. Destroying Iranian electricity infrastructure may increase pressure on the government, but it also imposes costs on millions of people who do not decide whether Hormuz remains open. The theory behind such coercion assumes that civilian suffering eventually translates into political pressure on leaders. Authoritarian systems can interrupt that transmission much more effectively than democracies because citizens have fewer mechanisms for changing policy. Collective economic pain therefore does not necessarily produce collective political leverage in the way the coercing state expects.
There is also a philosophical distinction between compellence and punishment. Compellence uses threatened costs to produce a specific behavioural change: reopen the strait and the threatened attack does not occur. Punishment inflicts suffering because the adversary has behaved wrongly or to demonstrate resolve. Trump’s ultimatum can still function as compellence because it contains an identifiable condition Iran can satisfy. That is strategically preferable to an open-ended threat because Tehran knows what behaviour supposedly prevents the next escalation. The danger arises if Iran complies and Washington simply introduces another demand immediately afterwards. Coercion works only when the target believes compliance actually purchases something. If concessions merely reveal weakness and generate additional demands, resistance becomes rational even when it is expensive.
This is the credible-off-ramp problem that has haunted the war from the beginning. America needs to communicate not only what happens if Iran refuses, but what happens if Iran accepts. Does reopening Hormuz produce an immediate halt to infrastructure strikes? Does it begin negotiations over sanctions and nuclear restrictions? Does Washington still seek major political change inside Iran? If Tehran believes the ultimate American objective remains weakening or overthrowing its government regardless of concessions, then preserving leverage over Hormuz becomes more valuable, not less. A state expecting existential defeat has little reason to surrender bargaining assets gradually.
Iran faces the mirror problem. Blocking Hormuz can impose extraordinary costs internationally, but those costs do not fall only on America and Israel. China, India, Japan, South Korea and Gulf states all depend heavily on stable energy flows. The longer Tehran uses the strait as a coercive instrument, the more it risks converting governments that might otherwise favour de-escalation into governments with a direct material interest in opposing Iranian behaviour. Leverage therefore has diminishing returns. An instrument becomes less valuable when using it encourages everyone affected to invest in eliminating their dependence on it.
This is already the long-term strategic danger for Iran. Hormuz is powerful precisely because so much energy depends upon it. Every prolonged closure strengthens investment in alternative pipelines, strategic reserves, non-Gulf suppliers and eventually energy sources requiring less imported oil. Iran can exploit geographic dependence today while simultaneously accelerating the policies that reduce the value of that geography tomorrow. This is the same weaponisation-of-interdependence paradox visible in American tariffs and Chinese rare-earth controls: using dependence as leverage teaches everyone dependent on you to diversify.
India should take that lesson especially seriously. The present shock again demonstrates that strategic autonomy cannot rest only on maintaining diplomatic relationships with competing powers. India also needs material autonomy through resilience: diversified energy suppliers, larger reserves, alternative shipping arrangements, more domestic electricity production and declining oil intensity over time. No foreign policy can prevent every war. The objective is ensuring that wars India did not choose do not narrow Indian economic choices excessively.
Trump’s Tuesday deadline also illustrates a recurring weakness of highly personalised foreign policy. Public deadlines can increase pressure because retreat becomes costly for the adversary, but they also reduce the coercer’s own flexibility. If Iran refuses and Trump does not attack, American credibility may appear weakened. If Iran refuses and Trump attacks even when advisers conclude additional escalation is strategically unwise, the deadline has partially trapped the president inside his own rhetoric. Credibility is valuable, but a leader can become too invested in appearing credible to reconsider whether the original threat remains rational. Statecraft requires preserving enough ambiguity that policy can adjust when circumstances change.
This is where institutional deliberation becomes valuable rather than obstructive. Congress, military advisers, intelligence agencies and diplomats exist partly because no leader possesses complete information. The more consequential the proposed target set becomes, particularly when civilian infrastructure is involved, the stronger the argument for rigorous legal and strategic scrutiny. Executive decisiveness is useful during immediate emergencies; prolonged war requires something more than speed. It requires repeated examination of whether means still correspond to ends.
After more than a month of war, that relationship remains unclear. Iran’s military capability has been damaged severely and its leadership transformed, yet Hormuz remains constrained, oil prices remain elevated and Tehran has not accepted Washington’s broader demands. The United States has therefore demonstrated overwhelming tactical capacity without yet producing a stable strategic settlement. That is not the same thing as military failure. It is evidence that destruction and political persuasion operate through different mechanisms.
The Tuesday deadline could become useful if it produces negotiations in which reopening Hormuz is exchanged for a genuine de-escalatory step and eventually a verifiable nuclear settlement. It becomes much more dangerous if every failed ultimatum simply creates another target category and another deadline. Wars become open-ended when success is defined as the adversary finally deciding not to resist.
America has enough power to destroy Iran’s bridges and electricity infrastructure. Iran has enough geographic leverage to keep imposing costs on the wider economy. Neither capability by itself answers the political question beneath the conflict. The measure of power now is not which side can inflict more pain; it is which side can convert the leverage it still possesses into an agreement before the destruction required to demonstrate resolve becomes larger than the security either side originally hoped to gain.
