Trump’s Iran War Is Becoming a Test of Political Will by Peter Rodgers

 Iran does not need to defeat the U.S. military if prolonged conflict can turn energy disruption and war fatigue into political pressure in Washington.

On August 31, renewed fighting between the United States and Iran pushed Brent crude above $91 a barrel. U.S. forces had struck Iranian launchers on Larak Island in the Strait of Hormuz, and Tehran said it retaliated against American bases in Jordan. The exchange came only days after President Donald Trump’s administration prepared to meet refiners and fuel retailers over rising gasoline prices ahead of the November midterm elections. Six months into the war, the contest is no longer only about military damage. It is increasingly about political endurance.

That shift points to the central vulnerability Iran can try to exploit. Tehran does not need to defeat the U.S. military in a conventional war, and it has little realistic prospect of doing so. What it can seek instead is to make the continuation of the conflict progressively more expensive for Washington—economically, politically, and electorally. The relevant contest is therefore not simply over who can strike harder, but over whose political system can absorb the costs of a prolonged confrontation for longer.

For Iran, that logic has a historical foundation. The eight-year Iran-Iraq War began when Saddam Hussein invaded Iran in 1980, at a moment when the Islamic Republic was still recovering from revolution and institutional upheaval. Iraq drew heavily on foreign weapons; the Soviet Union remained its largest supplier, while Washington eventually tilted toward Baghdad with political, commercial, intelligence, and other forms of support after 1982 as U.S. officials feared an Iranian victory. Iran suffered enormous losses and did not achieve a decisive victory of its own, but Iraq also failed to force the political settlement it had sought at the outset.

The lesson embedded in Iran’s political memory is not that a weaker state can always defeat a stronger coalition. It is narrower: survival can itself deny an adversary its political objective, and time can become an instrument of strategy. That experience helps explain why pressure intended to compel rapid Iranian capitulation can produce the opposite calculation in Tehran—endure the immediate damage, avoid a direct contest on American terms, and wait for the costs of the war to accumulate elsewhere.

The Strait of Hormuz gives that strategy an unusually powerful economic channel. According to the U.S. Energy Information Administration, about 20 percent of global petroleum liquids consumption passed through the strait in the first half of 2025. Iran does not have to shut the waterway completely to affect expectations. Threats to shipping, intermittent disruption, higher insurance costs, and uncertainty over energy flows can all move prices. The current war has already demonstrated how quickly a military exchange in the Gulf can reach consumers thousands of miles away.

That matters because American political will is tied to domestic economic conditions in a way battlefield calculations are not. By late August, U.S. regular gasoline was above $4 a gallon, roughly a dollar more than a year earlier. For voters, the strategic arguments over deterrence, nuclear risk, or regional order compete with a much simpler measure of the war’s cost: what they pay at the pump and how higher energy prices feed into transportation, food, and other household expenses. As those costs persist, foreign policy becomes domestic politics.

The political pressure is already measurable. A late-August Reuters/Ipsos poll found that only 31 percent of Americans supported U.S. military action against Iran, while 83 percent expected the war to continue for an extended period. Trump’s job approval stood at 33 percent. Those figures do not prove that the Iran war alone is driving American politics, nor do they guarantee that public frustration will force a change in strategy. But they show that the political cushion for a prolonged conflict is narrowing at the same time that its economic effects remain highly visible.

American history gives Tehran reason to take that vulnerability seriously. Vietnam, Iraq, and Afghanistan were very different wars, and none offers a simple template for the current conflict. Yet each illustrated a broader problem: military superiority does not automatically preserve domestic support for an open-ended mission. A government can continue to possess overwhelming military power even as public confidence in the purpose, cost, or attainability of the war erodes. In that sense, political exhaustion can arrive well before conventional military defeat.

This does not mean time automatically favors Iran. Attrition cuts both ways. Iran has absorbed severe military and economic damage, and prolonged disruption of Gulf trade also hurts its own economy and encourages regional states to develop routes that bypass Hormuz. The United States retains vastly greater military and financial capacity. If Washington can define a limited objective, sustain domestic support, and convert military leverage into a durable settlement, Tehran’s bet on political exhaustion can fail.

The danger for Trump is that a strategy built around maximum pressure can make that conversion harder if success is defined as Iranian surrender rather than a specific, attainable political outcome. Each additional strike can impose real costs on Tehran, but it can also prolong the period in which gasoline prices, inflation concerns, casualties, and the approaching elections shape the American debate. The more open-ended the objective becomes, the more the conflict begins to test political patience rather than military capacity.

That is the strategic logic Washington must confront. Iran does not need to destroy American forces or match U.S. firepower to benefit from a war of attrition. It needs only to remain capable of resistance while the costs of continuing the war become harder for an American administration to justify at home. The renewed fighting around Hormuz shows how quickly those costs can move from missile sites and naval routes into energy markets and electoral politics. If Washington wants to deny Tehran that advantage, it needs more than military superiority; it needs a credible end state. The longer the war continues without one, the more its decisive battlefield risks shifting from the Persian Gulf to American politics.
