A War Looking for an Exit
The conflict between the United States and Iran that began on February 28 2026 with the launch of Operation Epic Fury — the joint US-Israeli campaign of airstrikes targeting Iranian military infrastructure nuclear facilities and senior leadership including a strike that killed Supreme Leader Ali Khamenei — has now entered its fourth month in a state of suspended animation. A nominal ceasefire declared on April 8 2026 following intensive mediation by Pakistan has been violated repeatedly by both sides through proxy attacks naval confrontations drone strikes and public ultimatums yet has not formally collapsed into resumed full-scale warfare. As of May 21 2026 the diplomatic track — led by Pakistan and supported by China following the Beijing summit between Trump and Xi Jinping — represents the world's best and perhaps only realistic path to a resolution that avoids a return to the kind of intensive combat operations that characterised the opening weeks of the conflict and caused enormous destruction across Iran and significant casualties on all sides.
The issues under active discussion in the Pakistan-mediated framework are well defined even if agreement on any of them remains elusive. Freedom of navigation through the Strait of Hormuz — the narrow waterway between Iran and Oman through which approximately 20 percent of the world's oil trade normally passes and which remains effectively closed with approximately 1600 commercial ships stranded — is the most economically urgent item on the agenda and the one most directly linked to global oil prices and inflation in major economies. Iran's nuclear and ballistic missile programme is the issue of greatest strategic importance to the United States and Israel and the one on which the gap between the two sides' positions is most fundamental. Post-war reconstruction assistance and the lifting of US economic sanctions are the items of greatest importance to Iran domestically and the ones that Tehran's negotiators have consistently placed at the centre of their proposals for a comprehensive peace agreement.
The Ceasefire That Has Held Despite Everything
The durability of the April 8 ceasefire — however imperfect and however frequently violated — is itself a significant diplomatic achievement that should not be underestimated. The agreement was reached after President Trump had set three successive deadlines for Iran to accept his terms — March 21 then March 23 then April 7 — threatening attacks on Iranian energy infrastructure and bridges if a deal was not concluded by each deadline. On each occasion the deadline passed without full agreement and without resumed American strikes as Pakistan worked to keep the channels of communication open and to find formulations that could bridge the gap between Washington's demands and Tehran's red lines. The eventual April 8 agreement involved a two-week ceasefire — subsequently extended — linked to Iran agreeing to allow safe passage through the Strait of Hormuz and to engage in direct negotiations in Islamabad.
Trump initially described Iran's 10-point proposal as workable before later calling it fraudulent — a characterisation shift that reflected both the genuine difficulty of the negotiating positions and the domestic political dynamics in Washington where hawks within the administration and in Congress were pushing for harder terms than the diplomatic process was producing. The Islamabad talks themselves lasted 21 hours and concluded without a comprehensive agreement with US Vice President JD Vance stating afterward that Iran had refused to accept American terms. Yet the ceasefire endured and Pakistan continued its mediation role. By May 21 2026 the Pakistani prime minister had confirmed that his government remained in contact with both Washington and Tehran day and night — a description of diplomatic engagement that if accurate reflects an extraordinary level of sustained effort by a country playing a mediating role between two nuclear-armed adversaries in a conflict affecting the global economy.
What a Deal Would Need to Include
For a durable peace agreement to emerge from the current diplomatic process it will need to bridge several fundamental gaps that have defined the negotiating positions of the two sides throughout the war and its aftermath. On the Strait of Hormuz both sides nominally agree that commercial navigation should resume — a position affirmed in the joint US-China statement at the Beijing summit — but they disagree about the conditions under which that resumption would occur and about the long-term status of Iranian maritime authority in the strait. Iran's proposal for international recognition of its sovereignty over the Hormuz waterway is something the United States categorically rejects as incompatible with established principles of international maritime law and as representing a precedent that would give Tehran permanent leverage over global energy trade.
On the nuclear programme the United States and Israel require verifiable limits on Iran's uranium enrichment activities dismantlement of the most sensitive components of Iran's nuclear infrastructure and an inspections regime that would provide high confidence that Iran is not pursuing weaponisation. Iran's position has consistently been that its nuclear programme is peaceful and that it has the sovereign right to develop nuclear technology for civilian purposes — a position enshrined in the Nuclear Non-Proliferation Treaty to which Iran remains a signatory despite its estrangement from the international community on nuclear matters. Bridging these positions would require Iran to accept limits on its programme that it has previously rejected as incompatible with national sovereignty and would require the United States and Israel to accept a level of verification assurance that falls short of the complete dismantlement they have publicly demanded.
China's Role and the Post-Summit Landscape
The Trump-Xi summit in Beijing in mid-May produced one concrete commitment relevant to the Iran situation — a bilateral agreement by both the United States and China that the Strait of Hormuz must remain open to commercial traffic. That commitment while framed in general terms represents the first formal alignment of American and Chinese positions on the Hormuz question and potentially gives Chinese diplomats leverage to press Iran — which values its economic relationship with China as a lifeline against the effects of US sanctions — to accept conditions for reopening the strait that fall within the range of what the United States would find acceptable. Whether Chinese diplomatic pressure on Iran has actually materialised and with what effect is not fully visible from public reporting but the structure of incentives suggests that Beijing has reason to push for a resolution given the severe disruption that the Hormuz closure has caused to Chinese energy supplies and the significant additional cost Chinese importers are paying for oil sourced from alternative suppliers during the blockade period.
Iran's new supreme leader Mojtaba Khamenei — who succeeded his father Ali Khamenei following the latter's death in the Israeli strike that triggered the war — has maintained a posture of defiance in his public statements while permitting the diplomatic process to continue. The combination of severe military damage to Iran's defence infrastructure and energy facilities the economic cost of sustained US sanctions and the Hormuz closure and the death toll of more than 1400 Iranians in the conflict creates genuine pressure on Tehran to find a resolution but also creates domestic political constraints on a leadership that cannot be seen to capitulate to American and Israeli demands. The path to a deal if one exists runs through a formulation that allows both sides to characterise the outcome as a victory — Iran as having defended its sovereignty and extracted economic concessions and the United States as having secured meaningful limits on Iran's nuclear programme and the permanent reopening of Hormuz. Whether such a formulation can be found with Pakistan's continued help and China's background pressure remains the defining diplomatic question of this extraordinary and consequential moment in Middle Eastern and global history.
