Mearsheimer: Iran Will Not Give Up Strait Control — ‘We’ve Basically Lost This War’
Reflecto News | Geopolitics | Iran-US Conflict
CHICAGO — Prominent international relations scholar Professor John Mearsheimer has delivered a stark assessment of the Iran-US war, arguing that Washington has “basically lost” the conflict and will ultimately be forced to make significant concessions to Tehran because the Iranian leadership will never relinquish control of the strategic Strait of Hormuz.
“The Iranians are not going to give up control of the strait… that’s their leverage. They’d be crazy to give up control of the strait. We’ve basically lost this war. You’re going to end up making concessions to the Iranians.”
— Prof. John Mearsheimer, University of Chicago
🎯 The Strait of Hormuz: Iran’s ‘Golden Lever’
Mearsheimer identified the Strait of Hormuz as the single most important asset in Iran’s strategic arsenal—and one that Tehran has proven it can effectively close at will.
The strait normally carries approximately 20% of the world’s oil supply and roughly one-third of global LNG shipments. Since the war began on February 28, Iran has effectively blocked the passage, causing global energy prices to spike to approximately $110–115 per barrel.
According to Mearsheimer, the ability to cut off this waterway is a trump card that Tehran will never surrender in any negotiation.
Iran has demanded a “new legal regime” in the strait that would formalize its ability to regulate transit and levy fees on passing ships—a demand the US has flatly rejected.
The US has demanded that Iran return to the pre-war legal status quo, with unimpeded freedom of navigation—an outcome that would strip Tehran of its most potent leverage.
The impasse over the strait is the central reason peace talks have stalled. Iran’s latest proposal—to reopen the strait and agree to a ceasefire, but postpone nuclear negotiations—was rejected because it left open the possibility that Iran would retain effective control of the waterway even after the war ends .
⚔️ ‘We’ve Basically Lost This War’
Mearsheimer’s claim that the United States has “basically lost” the war is striking given that Iran has not achieved a decisive battlefield victory. However, his assessment focuses on political objectives rather than territorial control.
Key Indicators of US ‘Defeat’ in Mearsheimer’s Framework:
| US War Objective | Current Status | Mearsheimer’s Assessment |
|---|---|---|
| Regime change or capitulation | Regime standing; no mass uprisings | Failed |
| Iran surrenders nuclear program | Iran continues enrichment; stockpiles intact | Failed |
| Iran yields control of Strait of Hormuz | Iran blocks passage; US has not reopened | Failed |
| US re-establishes deterrence | Iran has absorbed strikes and continued fighting | Failed |
Mearsheimer also argues that the US entered the war without an exit strategy and without the ability to achieve its maximalist objectives.
European leaders have echoed this frustration. German Chancellor Friedrich Merz recently stated that the US had launched the conflict without consulting allies, that he did not see a “convincing negotiating strategy,” and that Tehran had proven “clearly stronger than one thought.”
💣 The Bombs vs. Leverage Debate
Mearsheimer’s analysis directly contradicts President Trump’s recent claim that Iran is in a “state of collapse” and urgently seeking to reopen the strait.
In Mearsheimer’s view, the US naval blockade is economically painful for Iran, but Tehran’s ability to close the strait in response is equally painful for the global economy—and that pain is what gives Iran negotiating leverage.
President Trump has told advisers that “all [Iran’s leaders] understand is bombs,” but Mearsheimer argues that the opposite is true: what they understand is leverage. As long as Iran can block 20% of the world’s oil supply, it can force the global community to pay attention to its demands.
🔮 What Comes Next: Concessions
Mearsheimer’s prediction—that the US will “end up making concessions to the Iranians,” suggests that the current stalemate will not end with Iranian capitulation but with a negotiated settlement that falls far short of the administration’s initial war aims.
Potential concessions could include:
- Accepting Iran’s phased proposal – Ceasefire and strait reopening first, nuclear talks deferred.
- A “new legal regime” for the strait – Codifying Iran’s role in regulating transit.
- Sanctions relief – Gradual lifting of the blockade and economic restrictions.
The concessions, if they come, will not be announced as defeats. Instead, they will be framed as “peace with honor,” “creative diplomacy,” or “a deal that puts American interests first.” But in Mearsheimer’s assessment, the underlying reality will be the same: a war that began with maximalist ambitions will end with a settlement that looks much like what could have been negotiated before the first shot was fired.
📋 Key Takeaways
| Aspect | Summary |
|---|---|
| Mearsheimer’s Claim | Iran will not give up control of the strait — “They’d be crazy to” |
| US War Outcome | “We’ve basically lost this war” |
| What Loss Means | US cannot achieve maximalist war aims (regime change, nuclear surrender, strait control) |
| What Comes Next | US will be forced to make concessions to Iran |
| The Leverage Factor | Control of 20% of world oil supply gives Iran enduring negotiating power |
| The Strait Impasse | US demands pre-war status quo; Iran demands “new legal regime” |
| Likely Outcome | Negotiated settlement that restores Iranian oil exports in exchange for strait reopening — with nuclear program intact |
