Iran Submits De-escalation Proposal Via Pakistan: Reopen Strait of Hormuz in Exchange for Lifting Naval Blockade; Nuclear Talks Deferred

On April 28, 2026, Iran submitted a de-escalation proposal through Pakistan — the back-channel intermediary that has served as conduit since Islamabad Round 1 (April 11–12) — offering to reopen the Strait of Hormuz to commercial shipping in exchange for the US lifting its naval blockade of Iranian ports. The proposal explicitly defers resolution of Iran's nuclear program until after the immediate military conflict is resolved, a sequencing that the Trump administration has publicly signaled it opposes. Senior US officials expressed skepticism: accepting Iran's proposal without securing nuclear commitments first would surrender crucial bargaining leverage, potentially allowing Iran to reopen its key strategic chokepoint — through which approximately 20% of global oil trade flows — without meaningful constraints on its enrichment program. Iran's position was conveyed through Pakistani diplomatic channels, preserving the same indirect format established after Tehran's Foreign Ministry publicly denied any direct US–Iran talks during the April 25 Islamabad visit. Al Jazeera reported that both sides expressed deep distrust, with Iran stating 'Washington could no longer dictate terms' while US officials feared a 'frozen conflict' outcome. Axios confirmed Pakistan's mediator role in conveying the proposal, which arrived just two days after Trump cancelled Witkoff and Kushner's Pakistan trip (April 26) calling Iran's previous offer 'not enough.' The Hormuz proposal represents a tactical pivot after two collapsed Islamabad rounds: Iran shifts the first-order demand from nuclear enrichment sequencing to economic and maritime de-escalation, hoping to ease the blockade pressure while preserving its nuclear program from immediate constraint. The indefinite ceasefire extended by Trump on April 21 remains technically in force; the core enrichment gap (US demands 20 years, Iran offers 5) is unchanged.
