Trump Bet Iran Would Capitulate Before Hormuz Closed. The Strait May Now Be His Biggest Strategic Misread
According to the Wall Street Journal, Donald Trump told aides he believed Iran would fold before seriously shutting the Strait of Hormuz. That assumption now looks like one of the most consequential bets of the war.
Wars are often remembered for the explosions people saw. They are more often shaped by the assumptions leaders made before those explosions began.
One such assumption now sits near the center of the U.S.-Iran war: the belief, reported by the Wall Street Journal, that Donald Trump thought Iran would capitulate before moving to close the Strait of Hormuz, and that even if Tehran tried, the United States could simply overpower it and reopen the waterway.
This is the sort of assumption that can sound reasonable in peacetime briefings. On paper, the United States is stronger. Its naval reach is wider. Its air power is overwhelming. Iran's navy is smaller, older and more vulnerable in a conventional fight. From a conventional balance-of-forces perspective, reopening a strait sounds like the kind of task empires tell themselves they exist to perform.
But Hormuz was never a conventional problem.
That is the first and most important lesson.
The strait is narrow, commercially vital, geographically hostile, and ideally suited to the kind of asymmetric disruption Iran has prepared for over decades. Mines, fast boats, drones, coastal launchers, anti-ship missiles, insurance panic, electronic confusion and the political reluctance of commercial operators can combine to create a form of closure that does not require Tehran to physically seal every mile of water. It only has to make passage unsafe enough, unpredictable enough and expensive enough that normal traffic collapses.
Reuters has already reported how severely flows through the waterway have been disrupted and how shipping confidence, not only physical passage, has become part of the battlefield. That distinction matters. A strait can remain technically open while commercially unusable. And for energy markets, that is often enough.
If Trump believed Iran would fold before reaching for this lever, then he misread not merely Tehran's tolerance for pain but its theory of leverage.
Iran cannot win a symmetric war against the United States. It can, however, try to make symmetric victory economically self-defeating.
This is where the debate becomes more interesting than partisan slogans.
Trump's defenders would argue that the mistake was not misjudging Iran's will, but failing to hit its coercive instruments harder and earlier. From that point of view, the answer is not restraint but sharper force: neutralize mine-layers, destroy coastal launch networks, devastate Kharg Island's military functions, and make continued disruption too costly for Tehran to sustain. In that reading, the problem is incomplete application of American power.
Trump's critics argue something different: that the administration treated Hormuz like a shipping-security challenge when it was actually a strategic trigger. Once the war began without a realistic diplomatic backstop, the closure of the strait was not an outlier. It was one of the most predictable consequences available to Iran.
Both arguments contain some truth. That is exactly why the strait has become so politically dangerous.
If you say the U.S. can reopen it easily, you create an expectation that any prolonged disruption reflects failure. If you say the U.S. cannot reopen it quickly, you admit that Iran possesses a degree of real leverage despite battlefield losses. Policymakers dislike both options, because each carries a cost.
One cost is economic. Oil does not wait for grand strategy to become clear. Traders price fear early and nuance late. Even rumors of restricted passage, conditional clearances, or widening tanker risk can move crude, freight, insurance and inflation expectations in ways that no White House communications strategy can easily contain. That is why Hormuz has always been more than a maritime chokepoint. It is an inflation machine with military consequences.
Another cost is political. A president who says he has won but cannot yet restore secure passage through the world's most important energy artery invites a damaging question: won what, exactly? Territory? No. Regime collapse? No. Full deterrence? Hard to claim if insurers, shipowners and allied governments still act as though the waterway is under strategic duress.
A third cost is allied confidence. Gulf partners, European importers and Asian buyers do not experience the strait as an abstract test of resolve. They experience it as an artery connected to fuel bills, industrial planning, sovereign budgets and domestic political stability. If Washington underestimated Tehran's willingness to use that artery as a weapon, allies will wonder what else was underestimated.
This is also why the public debate over escorts and reopening plans matters. Escorting a tanker is not the same as restoring commercial normality. A warship can accompany a ship through danger. It cannot, by itself, restore the insurance market, undo risk premiums, or guarantee that every civilian operator will resume routine passage. Military presence can lower tactical risk while leaving strategic fear intact.
That may be the central misreading.
Trump appears to have treated Hormuz as a physical obstacle to be overcome. Iran appears to treat it as a psychological and economic landscape to be poisoned.
In that contest, raw military superiority helps, but it does not settle everything.
There is also a deeper irony. The more Washington insists Iran is badly weakened, the more observers will ask why such a weakened adversary still holds the most powerful economic lever in the war. The strait has become a way for Iran to rebut the narrative of total defeat without needing a conventional breakthrough. As long as Hormuz remains unstable, Tehran can say: you may dominate the sky, but we still influence the price of your victory.
So was Trump irrational to assume Iran might capitulate? Not necessarily. Leaders gamble all the time on the belief that shock and pain will induce caution in an adversary. Sometimes they are right. But the quality of a gamble depends on whether the losing scenario is survivable.
Here, the losing scenario is global energy disruption, military overextension, allied anger, and an adversary that looks strategically bloodied yet not strategically broken.
That is a very expensive way to discover the difference between battlefield dominance and systemic control.
The Strait of Hormuz may yet reopen more fully. Traffic may normalize. Iran's capacity to sustain disruption may erode. Diplomacy may create off-ramps.
But the political damage to the original assumption is already done.
Trump appears to have believed the threat of American force would stop Iran from reaching for its strongest lever. Instead, the lever became the war's organizing fact.
And once that happens, every new strike, deployment and press conference has to answer the same question:
If the United States saw Hormuz coming and still could not prevent this outcome, was the war planned around the wrong measure of power from the start?
