How long will the US-Iran war last?
American war strategy is hostage to the American electoral calendar. President Trump will be asking: what does this war do to my numbers in the mid-term election in November? Yes, the war cabinet is speaking the language of national interest and regional stability, but the real map on the wall is not the Middle East — it is the swing states. History is unambiguous on this: Nixon prolonged Vietnam negotiations to win 1972. Bush declared “mission accomplished” with one eye on 2004. Obama’s withdrawal timelines from Afghanistan were written by pollsters as much as generals.
It is not in President Trump’s interest to prolong the conflict, particularly with November approaching.
For the record, Tehran enters this war not from strength but from defiant weakness. The economy was already on life support before the first missile was launched — decades of sanctions, a collapsing currency, inflation above 40 percent, and a middle class out protesting. Yes, the IRGC can absorb punishment but the Iranian bazaar cannot – no more.
A prolonged war would not only strain military logistics, it would accelerate an economic collapse already underway. The regime understands this arithmetic. A short war may be survivable. A long war risks finishing what sanctions began — an economic implosion that threatens the regime itself.
Beijing rarely telegraphs its hand, but in this war its interests are clear. China is the world’s largest importer of Gulf oil, and the Strait of Hormuz is the artery feeding its factories, power grid and growth. A prolonged disruption does not just raise Beijing’s energy bill; it threatens the economic stability on which the Communist Party’s legitimacy rests. China has spent two decades building energy partnerships and the Belt and Road across the Gulf. A long war would put that investment at risk. Beijing will not say this loudly, but its message is clear: end this quickly.
Riyadh’s position in this war is simple. A short conflict that pushes oil prices higher is a fiscal windfall. Yes, every extra dollar per barrel flows into Vision 2030 and the sovereign wealth funds. But there is a hard ceiling. The moment instability becomes a security threat, the calculus changes. The Gulf monarchies want this war short — not because of oil, but because they live in the neighborhood.
Israel is a country of nine million people that has been on a war footing since October 2023. Reserves mobilized. Economy under strain. Diaspora support no longer as automatic as it once was. For Israel, the real question is not military capability. For Israel, the real question is whether Israel’s domestic politics can sustain a long war.
Europe has not forgotten 2022. LNG panic. Emergency price caps. Governments shaken by energy bills families could not pay. Another Gulf disruption would reopen that wound. Higher gas prices would not just strain budgets — they would shake politics. Populist parties are already close to power, and nothing fuels them faster than a heating bill that doubles overnight. European leaders will stand with Washington in public. In private, they will be searching for an exit ramp.
To be certain, elevated oil prices are inflationary, and inflation means central banks cannot cut rates. Half the world is sitting on debt that needs cheaper money to refinance. A long war keeps rates higher for longer, and that pain is felt from Buenos Aires to Nairobi to Jakarta. This gives the IMF, the World Bank, and the G20 a quiet but powerful interest in a short war.
And yet, wars have a logic of their own. Once started, they rarely end on the schedule that rational actors would prefer.
So how long will this war last? Every major stakeholder — China, the Gulf states, Japan and Europe — quietly prefers an exit. The United States and Iran face domestic political clocks that a long war would strain. Wars usually end when the cost of continuing exceeds the cost of stopping. That moment, for many players in this conflict, may not be far away. The real question is not whether an exit ramp appears — but who claims credit for building it.
