A sweeping interim agreement between the United States and Iran was signed Wednesday, June 17, 2026 and the world exhaled. For a few hours, at least. The deal promises a ceasefire, open oil lanes, and a 60-day window to hammer out permanent peace. But the closer you look at it, the more it resembles a patch job on a crumbling wall rather than a finished building.
Here’s everything you need to know including the three things that could blow it all up before the month is out.
A Deal Signed Remotely, With the World Watching
U.S. President Donald Trump signed the agreement from the G7 summit in France. Iranian President Masoud Pezeshkian signed from Tehran. The document, a 14-point memorandum of understanding now known as the Islamabad Memorandum was exchanged digitally, with world leaders watching closely.
French President Emmanuel Macron and the broader G7 bloc quickly praised it as a critical win for global economic stability. And on paper, it’s easy to see why. The deal covers an enormous amount of ground.
What the Deal Actually Says
The agreement establishes a 60-day ceasefire to halt active hostilities and open the door for a final, permanent peace settlement. Within those 60 days, both sides commit to several immediate, concrete moves:
Strait of Hormuz reopens immediately. Iran has agreed to reopen the vital maritime chokepoint, toll-free for the entire 60-day window. This single clause alone could prevent what economists were calling an imminent global economic depression. At the height of the conflict, oil shipments through the Strait had slowed to a trickle from the usual 15 million barrels a day.
Immediate sanctions relief for Iran. The U.S. Treasury is issuing waivers that allow Iran to freely export crude oil, petroleum products, and access international banking services. The U.S. has also lifted its two-month naval blockade on Iranian ports.
Iran dilutes its uranium stockpile. In one of the most significant nuclear concessions in years, Iran has agreed to down-blend its 440kg stockpile of 60%-enriched uranium reducing it to a lower purity level under direct supervision from the International Atomic Energy Agency (IAEA).
Hezbollah is expected to stand down. The deal calls for an immediate and permanent end to military operations on all fronts, explicitly including Lebanon. In practical terms, this means Iran is being asked to rein in Hezbollah.
Frozen assets and a massive reconstruction fund. The U.S. has signaled it will release frozen Iranian funds “as they behave,” and the deal proposes a $300 billion international reconstruction fund for Iran contingent on a final agreement being reached.
The Political Firestorm It Immediately Sparked
Not everyone was celebrating.
Trump called it a “major win” that pulled the world back from the brink of a global depression. But the backlash was swift. Hardline Republicans in Washington and Israeli officials immediately pushed back, arguing that the administration gave away too much leverage upfront handing Iran immediate oil export waivers without first securing a permanent dismantlement of its nuclear program.
The criticism isn’t just political noise. It reflects a real structural tension baked into the deal itself: the U.S. gave concrete, immediate relief in exchange for a promise of negotiations that haven’t even started yet.
Three Scenarios When the 60 Days Run Out
The Islamabad Memorandum is not a peace treaty. It’s a temporary framework, a diplomatic waiting room with a ticking clock. When those 60 days expire in August 2026, one of three things will happen.
If a Final Deal Is Reached
A successful negotiation triggers a cascade of long-term shifts. Broad U.S. sanctions against Iran would be permanently lifted, including pressure to remove relevant UN Security Council resolutions. The proposed $300 billion reconstruction fund would become a fully operational mechanism. The U.S. would also commit to withdrawing all naval and military forces from Iranian proximity within 30 days of a final signing. And the Strait of Hormuz, currently open on a temporary basis, would transition into a permanent maritime framework negotiated with Oman and Gulf states under international law.
If Both Sides Need More Time
The deal includes a mutual extension clause. If negotiators are making genuine progress but can’t resolve every technicality like the precise 10 to 20 year timeline for Iranian nuclear restrictions both sides can agree to extend the window by another 30 or 60 days. During any extension, all interim terms stay active: the Strait stays open, oil waivers continue, and both sides maintain the military freeze.
If the Talks Collapse
This is the scenario keeping defense analysts up at night. If 60 days pass with no deal and no extension, everything snaps back.
The U.S. Treasury waivers vanish. The naval blockade on Iranian ports would likely be reinstated. The “permanent termination of military operations” clause loses its legal weight, meaning the Israel-Hezbollah front in southern Lebanon could reignite almost immediately. And Iran would no longer be bound by IAEA oversight meaning it could rapidly resume high-purity uranium enrichment from scratch.
The uncomfortable truth is that comprehensive nuclear deals historically take years, not months. The 2015 JCPOA took nearly two years of intensive diplomacy to finalize. The idea of resolving decades of military confrontation, proxy conflicts, and nuclear brinkmanship in 60 days is extraordinarily ambitious which means the threat of a collapse is very real.
The Biggest Hole in the Whole Agreement: Israel Didn’t Sign It
Here’s the structural flaw that critics seized on immediately.
The Islamabad Memorandum is a bilateral agreement between the U.S. and Iran. Israel had no seat at the table and is not legally bound by it. Israeli Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz have already stated explicitly that Israel “preserves its freedom of action” and that Israeli forces will remain in southern Lebanon for as long as necessary.
This creates a chain reaction risk that looks something like this:
Israeli strike on Lebanon → Hezbollah retaliates with rockets → Iran declares the U.S. “failed its commitment” → Iran freezes nuclear down-blending and closes the Strait of Hormuz → U.S. snaps back its blockade and sanctions → the 60-day window collapses into open conflict.
Iran’s Foreign Minister Abbas Araghchi has already made Tehran’s position clear: if Israel keeps troops in Lebanon and continues its operations, Iran will hold Washington responsible, since the U.S. is Israel’s primary backer. Meanwhile, Washington’s position is that any Israeli action in Lebanon would be a separate conflict between sovereign nations, an argument Iran has flatly rejected.
What makes this even more precarious: limited Israeli strikes in southern Lebanon have already continued even after the electronic signatures were exchanged on Wednesday.
Tehran’s stated position is that it will refuse to sign a final nuclear deal if Israeli troops don’t fully withdraw from Lebanese soil. Jerusalem has flatly refused Washington’s request to scale back IDF presence. The U.S. and Iran, in effect, signed a peace deal that depends entirely on the restraint of a third party that openly opposes it.
Three Eggshells That Could Shatter This Week
Even setting aside the Israel question, the deal has three immediate pressure points, any one of which could crack the framework before it finds its footing.
The Lebanon front is the most immediate threat. If the IDF launches heavy airstrikes in Beirut or significantly advances its ground position, Hezbollah’s response would be automatic. Iran would then declare the U.S. in breach of the agreement, and the entire framework falls possibly within days of being signed.
The $12 billion upfront payment is already a political firestorm. According to leaked details from the 14-point MoU, the U.S. reportedly agreed to release $24 billion in frozen Iranian assets over the 60-day period with $12 billion to be released upfront, before nuclear negotiations even begin. If Trump delays or freezes this transfer due to domestic political pressure, Iran will almost certainly halt its uranium down-blending and walk away from the table.
Shipping companies aren’t buying it yet. Even with Trump announcing the naval blockade is lifted and Iran promising open passage through the Strait of Hormuz, commercial shippers and insurers are waiting. They know that if talks collapse, Iran could re-mine the Strait or the U.S. Navy could reinstate the blockade within hours. Defense Secretary Pete Hegseth openly stated the U.S. can “reimpose the blockade at any point”, a comment that, while transparently true, effectively told Iranian hardliners that the pause isn’t something they should fully trust either. Both sides are keeping their hands close to their weapons.
What This Deal Really Is
Strip away the diplomatic language and the press conference optimism, and what the Islamabad Memorandum really represents is a mutual agreement to stop shooting long enough to have a conversation.
That’s not nothing. Preventing a global economic depression is genuinely significant. Reopening the Strait of Hormuz even temporarily matters enormously to oil markets, supply chains, and every country that depends on Gulf energy.
But the deal’s durability rests on a stack of conditions, each one fragile: Israel holds back, Trump withstands domestic pressure on the asset transfers, Iran’s hardliners don’t sabotage the negotiations from the inside, and two nations with decades of deep mutual distrust somehow agree on a comprehensive nuclear framework in 60 days.
The world isn’t at peace. It’s just holding its breath.
