Zarif Proposes Iran Peace Framework as Trump’s April 6 Ultimatum Looms

Mohammad Javad Zarif, Iran’s former foreign minister, published a detailed U.S.-Iran peace framework on April 2, marking Tehran’s first major diplomatic overture since the February 28 assassination of Supreme Leader Ali Khamenei—72 hours before President Trump’s April 6 deadline to reopen the Strait of Hormuz or face infrastructure strikes.

The proposal, detailed in Foreign Affairs, includes Iran capping uranium enrichment below 3.67% (the 2015 JCPOA threshold), reducing stockpiles under international supervision, and reopening the Strait to commercial traffic in exchange for sanctions relief and a U.S.-Iran nonaggression pact. Zarif framed the offer as Tehran “declaring victory” after five weeks of military escalation that has disrupted 20% of global oil supply and pushed Brent crude to $126 per barrel.

The Framework

Zarif’s proposal centers on reversible nuclear restraint tied to economic normalization. Iran would cap enrichment at 3.67%, eliminate stockpiles above that threshold, and submit to IAEA monitoring—stopping short of dismantling centrifuge infrastructure. In exchange, the U.S. would lift oil sanctions, unfreeze $7 billion in Iranian assets, and negotiate a formal nonaggression treaty.

The Strait component is explicit: Iran retains sovereignty but commits to unrestricted commercial passage, ending the March 4 closure. Oil markets reacted cautiously—Brent crude remains above $100, a level first crossed on March 8, according to Bloomberg, as traders await U.S. response.

Zarif’s phrasing—”as an Iranian, outraged by Donald Trump’s reckless aggression”—signals the proposal’s dual audience: hardliners in Tehran and a U.S. administration he describes as “completely illiterate on both geopolitics and nuclear technicalities,” referencing envoys Steve Witkoff and Jared Kushner, per Al-Monitor.

Timing and Credibility

The proposal arrives amid unprecedented military escalation. Iran launched its largest ballistic missile barrage of the war on April 1—approximately 10 missiles targeting central Israel, part of 1,215 total launches since February 28, according to NBC News. U.S. Central Command claims 90% of Iran’s missile and drone capabilities are degraded, while Israeli forces report 70% of launchers destroyed.

Yet Iran’s conventional deterrence remains functional. On April 3, Iranian air defenses downed a U.S. F-15E Strike Eagle—one crew member rescued, search ongoing for the second, according to CBS News. Hours later, Trump struck the B1 Bridge near Tehran, killing eight civilians, and reiterated threats to destroy power plants if the Strait remains closed past April 6.

Zarif would not have published without senior approval, analysts note. His alignment with reformist President Masoud Pezeshkian suggests the proposal reflects factional compromise rather than rogue diplomacy. Iran rejected a U.S. 15-point plan on March 25, demanding reparations and sovereignty guarantees, per NPR. The new framework omits reparations but retains the Strait sovereignty clause—a potential negotiating concession.

Signal or Stall?

Trump has extended his Strait ultimatum three times—initially March 23, then March 26, now April 6—while insisting “they want to make a deal more than I want to make a deal,” according to CNBC. Energy markets interpret the delays as evidence neither side can afford total escalation: U.S. gasoline prices exceeded $4 per gallon on April 1, the highest since 2022, while Iran’s economy faces collapse from weeks of airstrikes.

The proposal’s substance is weaker than the 2015 JCPOA—no centrifuge dismantlement, no hard cap on advanced enrichment research—but stronger than Iran’s March 25 position, which demanded war reparations and offered no nuclear concessions. Whether it represents genuine flexibility or tactical positioning to fracture U.S.-Israel coordination before the April 6 deadline remains unclear.

Israeli officials have not commented publicly, but the timing—immediately after the largest Iranian missile barrage and the F-15E loss—suggests Tehran is demonstrating sustained conventional capability while offering an exit. Zarif’s argument: Iran has survived five weeks of intensive strikes, proven the Strait closure economically viable, and can now negotiate from strength rather than desperation.

What to Watch

The April 6 deadline, now 72 hours away, is Trump’s third extension. Another delay would signal serious back-channel progress; strikes on Iranian power infrastructure would confirm negotiations have collapsed. Oil markets are pricing 60% odds of Strait reopening by mid-April, per futures positioning tracked by CNBC, which warns supply disruptions will worsen significantly without resolution.

The F-15E incident adds pressure: if the missing crew member is confirmed killed or captured, domestic U.S. politics may narrow Trump’s negotiating room regardless of economic incentives. Conversely, successful crew recovery could provide political cover for a deal.

The next 72 hours will determine whether Zarif’s framework catalyzes genuine negotiation or becomes another tactical feint in a conflict whose escalation logic—oil shocks, infrastructure destruction, proxy warfare—now operates independently of diplomatic signals. The proposal’s core test: whether Iran’s reformists can deliver hardliner buy-in on reversible nuclear restraint, and whether Trump can accept a deal that leaves centrifuge capacity intact while declaring victory on Strait reopening and oil price stabilization.
