President Donald Trump and Iranian President Masoud Pezeshkian signed a memorandum of understanding Thursday to end hostilities in Lebanon and reopen the Strait of Hormuz, with the deal taking immediate effect despite lingering questions over its long-term durability.
Trump announced the agreement Wednesday after a meeting with French President Emmanuel Macron at Versailles, where he handed a physical copy of the document to Secretary of State Marco Rubio. The pact—brokered with Pakistani mediation—includes a 60-day window for formal negotiations, though its exact terms remain partially obscured by conflicting accounts from U.S. officials and Iranian state media. What is clear: the deal marks a dramatic shift in Middle East geopolitics, with oil markets reacting instantly and regional powers scrambling to assess its implications.
What the Deal Actually Says—and What It Doesn’t
The memorandum, confirmed by both Al Jazeera and AP News, includes three core commitments: an immediate ceasefire in Lebanon, the reopening of the Strait of Hormuz for two months without tolls, and a U.S. pledge to waive sanctions on Iranian oil exports. However, critical details—such as whether Iran will permanently dilute its uranium stockpile or how Lebanon’s territorial integrity will be enforced—remain unclear.
U.S. officials, speaking on condition of anonymity to AP News, described the agreement as a “framework” rather than a final deal. Trump’s signing at Versailles—captured on video by a White House aide—contrasted with earlier reports that he had digitally signed the document Sunday during the G7 summit. The discrepancy underscores the deal’s ad-hoc nature, with no official text yet released. Iranian state TV later aired a version of the agreement that aligned with the U.S. draft, though Tehran has not formally confirmed Pezeshkian’s signature.
The Timeline: From Digital Signature to Physical Ink
- Sunday, June 16, 2026: Trump and Pezeshkian digitally sign the memorandum during the G7 summit in Switzerland, per AP News. Pakistani Prime Minister Shehbaz Sharif, who mediated the talks, calls it “immediate effect” but notes a formal signing ceremony is planned for Friday.
- Wednesday, June 18, 2026: Trump physically signs the document at Versailles, handing it to Secretary of State Rubio amid applause. U.S. officials clarify the agreement is already active, though its enforcement mechanisms remain vague.
- Friday, June 21, 2026: Scheduled ceremonial signing in Switzerland, though the deal’s operational status is already in effect.
The rapid-fire timeline reflects the urgency of the crisis: Lebanon’s Hezbollah militant group has faced relentless Israeli airstrikes, while the Strait of Hormuz—through which 20% of global oil passes—has been a flashpoint for attacks by Iran-backed forces. The deal’s immediate reopening of the strait is a direct response to market fears over disrupted oil flows, with Brent crude prices dropping 3% on Thursday as traders reacted to the news.
Why Pakistan’s Role Matters—and What It Omits
Pakistani Prime Minister Shehbaz Sharif’s mediation role is the deal’s most underreported detail. As AP News notes, Sharif’s involvement reflects Islamabad’s delicate balancing act between Washington and Tehran. Yet the agreement’s silence on Iran’s nuclear program—despite Trump’s past rhetoric—has raised eyebrows. A U.S. official told AP that the memorandum requires Iran to “dilute its highly enriched uranium,” but does not mandate dismantling existing stockpiles.
This omission is critical. In 2015, the Joint Comprehensive Plan of Action (JCPOA) required Iran to reduce its uranium stockpile by 98%. The current deal’s language is far weaker, suggesting Trump’s priority was halting hostilities over long-term nuclear constraints. “It’s a memorandum of understanding,” Trump told reporters Wednesday. “‘If I don’t like it, we’ll go back to shooting at them, dropping bombs,’” he added, signaling the deal’s conditional nature.

The Strait of Hormuz: Oil Markets React Before the Deal Is Fully Tested
The Strait of Hormuz’s reopening is the deal’s most tangible immediate impact. As Al Jazeera reports, the two-month toll-free window is a critical lifeline for global energy markets, which have braced for disruptions since Iran-backed Houthi rebels in Yemen began targeting commercial ships in the Red Sea. However, the deal does not address the root cause: Iran’s support for militant groups like Hezbollah and the Houthis.
Analysts warn the pact’s durability hinges on two factors: whether Israel accepts Lebanon’s borders as final, and whether Iran’s Supreme Leader Ayatollah Ali Khamenei—who has not publicly endorsed the deal—considers it binding. “Nobody knows what it is, but it’s very strong,” one Iranian official told Al Jazeera, reflecting the uncertainty. The absence of a formal treaty means any party can walk away, leaving the region in a precarious standoff.
What Happens Next: The 60-Day Clock and Lebanon’s Uncertain Future
The next 60 days will determine whether the memorandum becomes a lasting ceasefire or collapses under unmet expectations.
- Friday, June 21: Formal signing ceremony in Switzerland, with Trump and Pezeshkian expected to attend. The event will test whether both sides can present a unified front.
- July 2026: Deadline for Iran to “dilute” its uranium stockpile, per U.S. officials. The lack of a clear verification mechanism raises questions about compliance.
- August 2026: Expiration of the Strait of Hormuz’s toll-free period. If no permanent agreement is reached, shipping costs could spike again.
- Lebanon: Hezbollah’s fate remains unresolved. Israel has not confirmed whether it will halt airstrikes, and the group’s armed presence in southern Lebanon—now a no-go zone for Israeli forces—could reignite conflict.
The deal’s biggest wild card is Israel. Prime Minister Benjamin Netanyahu has not commented publicly, but leaks suggest he views the agreement as a temporary pause rather than a permanent solution. “This is not a peace deal,” a senior Israeli official told Al Jazeera. “It’s a pause in the fighting.” The risk: if Israel perceives Iran or Hezbollah as violating the terms, it could resume operations, dragging the region back into war.
The Bigger Picture: How This Deal Compares to Past Attempts
This memorandum is the third major U.S.-Iran diplomatic effort in a decade, following the failed 2012 talks in Baghdad and the 2015 JCPOA. Unlike those agreements, this one lacks a formal verification process, making it vulnerable to backsliding. The 2015 deal included intrusive inspections by the International Atomic Energy Agency (IAEA), while today’s memorandum relies on trust—something both sides have historically struggled with.
Yet the current deal’s speed—negotiated in days rather than years—reflects the urgency of the moment. The Strait of Hormuz has been a tinderbox since 2019, when Iran seized foreign oil tankers and threatened to block shipping. The Red Sea crisis, exacerbated by Houthi attacks, has pushed global powers to act. “The market is breathing a sigh of relief,” said a trader at Vitol, one of the world’s largest oil traders. “But the real test is whether this holds.”
The deal’s success hinges on whether Trump and Pezeshkian can turn a fragile ceasefire into a framework for broader negotiations. For now, the focus is on survival: keeping the Strait open, halting the Lebanon war, and buying time for diplomacy. Whether that time is used wisely remains to be seen.
