The Islamabad Accord offers specific terms for the first time in six weeks of conflict, but Iran's military council holds the veto.

Key takeaway

Pakistan produced the terms; Iran's military council holds the veto.

Pakistan has produced the first concrete ceasefire framework of the war . The two-tier plan, negotiated overnight by Field Marshal Asim Munir, calls for an immediate ceasefire followed by a 15-to-20-day comprehensive settlement period. Iran would commit to abandoning nuclear weapons pursuit. In return: sanctions relief, frozen asset releases, and immediate Strait of Hormuz reopening. The memorandum of understanding would be finalised electronically, with Pakistan as the sole channel.

The key players in the room: Vice President JD Vance, Special Envoy Steve Witkoff, and Foreign Minister Abbas Araghchi. Ynet News reported the ceasefire could take effect as early as Monday 7 April, though this is a single-source claim that should be treated with caution.

Iran's civilian government, which might accept terms, cannot reach the Supreme Leader . The IRGC military council that controls access to Mojtaba Khamenei benefits from continued conflict. The Islamabad Accord asks the IRGC to negotiate away its own wartime authority. No ceasefire framework in history has succeeded when the veto holders profit from the war it would end.

China pledged strategic coordination with Pakistan on the mediation effort. Beijing's backing gives the accord geopolitical weight that previous mediation attempts lacked. But weight is not leverage. The accord exists because five empty deadlines created a vacuum. Whether it can fill that vacuum depends on actors in Tehran who have spent six weeks proving they answer to no one.

Deep Analysis

In plain English

Pakistan put forward a peace plan with specific terms for the first time in six weeks of war. The plan says: stop fighting immediately, then negotiate a full deal over the next two to three weeks. Iran would give up its nuclear weapons programme and get sanctions lifted in return. The problem is that the people who would need to agree to it in Tehran are the same people whose power depends on the war continuing.

Deep Analysis
Root Causes

The ceasefire vacuum exists because US coercive diplomacy required credible escalation, which five deadline extensions destroyed.

Pakistan's mediation opportunity is a direct consequence of Washington's inability to enforce its own threats. The IRGC's wartime power consolidation means the actors who could accept peace are not the actors who hold the veto.

Escalation

De-escalatory in intent, but the framework's existence does not change structural barriers. Iran's non-response is itself an escalation indicator: silence preserves optionality for the IRGC while the civilian government lacks authority to commit. If the accord collapses, the diplomatic space it briefly opened closes harder than before.

Different Perspectives
Israel
Israel
IDF Chief Eyal Zamir declared on 3 June there was no ceasefire for his forces, and strikes killed at least 10 civilians and one Israeli soldier on 4 June. The IDF killed Hezbollah's chief engineer and warned three south Lebanon villages to evacuate on 5 June, advancing into ground the unsigned Washington framework has not caught.
Hezbollah / Lebanon
Hezbollah / Lebanon
Naim Qassem rejected the Washington Lebanon framework on 4 June as "absurd, humiliating and insulting", blocking a ceasefire instrument that required Hezbollah to withdraw north of the Litani before any Israeli withdrawal. Over one million Lebanese remain displaced; the framework's collapse prolongs that toll.
Iran
Iran
Foreign Minister Araghchi publicly coupled the Lebanon ceasefire to the Iran-US nuclear track on 4 June, carrying IRGC authority rather than his own civilian mandate. The IRGC delegation has sent no HEU counter-proposal since Araghchi confirmed no progress that same day; Mojtaba Khamenei's 21 May order to keep the 440.9 kg stockpile inside Iran remains operative.
United States
United States
Rubio placed the Iran-US deal at 95 per cent complete on 4 June while the administration signed no Iran instrument and OFAC designated only Cuban targets. Trump separately disclosed and rejected an airlift plan to collect Iran's HEU stockpile, claiming the material is "entombed", a claim the IAEA cannot verify.
China
China
Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.
Bahrain
Bahrain
The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.
