Is There a Diplomatic Off-Ramp? What a Hormuz Settlement Might Actually Look Like

Wars are started with objectives. They end with negotiations. The question of what a diplomatic resolution to the current Hormuz crisis might look like is not merely academic — it is, for the millions of people suffering economic damage from a closed strait, the most practically important question in geopolitics right now. Yet it receives surprisingly little serious analysis, partly because the belligerents are not publicly signalling any interest in talks, and partly because the gap between their stated positions appears unbridgeable. Apparent unbridgeability, however, has never yet been the last word in diplomatic history.

What Iran Needs

Iran's minimum requirements for any settlement are easier to identify than to satisfy. At the most basic level, Tehran needs a cessation of military strikes — it cannot reopen a strait while its infrastructure is being bombed. Beyond the immediate ceasefire, Iran needs some form of security guarantee or face-saving arrangement that allows its leadership to present the reopening of the strait as a strategic choice rather than a capitulation, without which no Iranian government could survive the domestic political consequences.

On the nuclear question — the ostensible casus belli for Operation Epic Fury — Iran's position is that it has the right to a civilian nuclear programme under the Non-Proliferation Treaty. Any settlement that requires Iran to permanently abandon all uranium enrichment will be rejected by every faction of Iranian politics, including the reformists. A settlement that caps enrichment below weapons-grade, subject to rigorous IAEA inspection, with sanctions relief as the quid pro quo, is the architecture of the 2015 JCPOA — which the U.S. withdrew from in 2018. Returning to something like that framework, with modifications, is the most plausible outcome — but it requires the U.S. to effectively acknowledge that the bombing campaign did not achieve permanent nuclear disarmament.

What the US and Israel Need

For the United States, the minimum outcome is the reopening of the Strait of Hormuz and a credible mechanism for preventing Iran from acquiring nuclear weapons. The first is a clear and testable condition. The second is where the divergence between Washington and Jerusalem is most acute: Israel's war aim was not to delay Iran's nuclear programme but to permanently eliminate it. Netanyahu has stated explicitly that he will not accept any settlement that leaves Iran with enrichment capability. The tension between what the U.S. needs (a strait reopened, a manageable deal) and what Israel wants (Iran disarmed and defanged) is the central diplomatic problem of any negotiated settlement.

The Potential Intermediaries

Direct U.S.-Iran talks are politically impossible in the current environment on both sides. The diplomatic history of this region, however, is rich with creative intermediation. Oman has served as the primary back-channel between Washington and Tehran for decades — it was Omani intermediaries who arranged the secret talks that preceded the 2015 JCPOA. Qatar has also played this role. Both are still diplomatically engaged with Iran, have strong reasons to want the strait reopened, and have the institutional knowledge to facilitate contacts.

China is the other potential intermediary of significance. It has relationships with both the U.S. and Iran, has already demonstrated its diplomatic capacity in the region through the 2023 Saudi-Iran reconciliation deal, and has a powerful economic motive — its own oil supply — to see the crisis resolved. The diplomatic prize of being the party that ended the Hormuz crisis would be significant for Beijing's global standing project. Whether Washington is willing to accept Chinese mediation is a separate, and more contested, question.

The Shape of a Deal

The most realistic diplomatic outcome — were one to emerge in the near term — would likely involve a simultaneous cessation of U.S. strikes and Iranian strait closure, a commitment to negotiations on the nuclear question with a defined timeline, and a package of sanctions relief structured to give Iran economic incentives to remain at the table. It would not resolve the underlying tensions between Iran and Israel, the question of Iran's regional proxy network, or the long-term nuclear ambition. It would be a ceasefire and a framework — not a peace.

That may be insufficient from the perspective of those who went to war. But it would reopen one of the world's most important waterways, stabilise the global economy, and create space for the longer and more difficult negotiations that the underlying issues require. In diplomacy, as in medicine, sometimes stopping the bleeding is the first and most urgent task — and treating the underlying condition comes later.
