Pakistan has a basis for this role. It helped broker the June MOU and has kept channels open to Tehran and Washington, working with Qatar and other interlocutors. In October, army chief Field Marshal Asim Munir travelled to Tehran for renewed mediation and met Iranian leaders; the visit sustained engagement but produced no breakthrough. Pakistan’s border with Iran, security ties with Saudi Arabia and access to Western capitals give Islamabad a distinctive position. It should turn that access into a concrete initiative.Istanbul should establish an R4 E3 contact group to revive the MOU within a fixed period. Pakistan could present a revised text separately to Iran and the United States, then seek backing from the other six states. Türkiye can convene; Egypt and Saudi Arabia can bring Arab and Gulf perspectives; the E3 can shape nuclear and verification provisions. Oman and Qatar should join as facilitators with useful channels and direct maritime interests. The group must consult, not speak for, the parties.An updated MOU should preserve the original’s practical achievements while correcting its weaknesses.

Separate, parallel commitments or assurances would be needed to bring Israel into a de-escalation track. Any ceasefire must name the parties and provide a channel to address alleged violations.Second, the MOU should make safe passage through Hormuz an early, visible confidence-building measure and reaffirm freedom of navigation through Bab al-Mandab.
