Shehbaz Sharif, the high minister of Pakistan, which served as the important thing negotiator between the U.S. and Iran, introduced on June 14, 2026, that the 2 aspects had agreed on a deal to finish the warfare. It is going to be formally signed on June 19 in Switzerland.
President Donald Trump introduced it on Reality Social as a triumph, claiming that the Strait of Hormuz is open for everybody, the U.S. blockade has been lifted, and the oil is flowing once more. What Trump didn’t point out used to be Iran’s nuclear program and what occurs to its enriched uranium stockpile, some of the major causes cited for beginning the warfare.
The nuclear factor – in conjunction with core problems reminiscent of ballistic missiles and Iran’s proxies – has been deferred for 60 days.
This raises two necessary questions: What used to be the warfare in truth for? And what did the U.S. reach?
As a world and nuclear safety professional, I imagine the solution is not anything – and within the procedure the U.S. misplaced credibility as a negotiating spouse.
Why the nuclear query is the toughest
The “rationalist theory of war,” as advanced by way of political scientist James Fearon in 1995, identifies 3 issues that force states to warfare after they would favor to succeed in a deal: incomplete details about every different’s get to the bottom of; the lack to credibly promise a deal or dedication; and what world family members students name the indivisibility drawback – when the object in dispute can’t be break up or shared, as it leaves no center flooring to choose.
The warfare clarified the primary reason why. Each and every facet noticed what the opposite would in truth do – how a lot power the U.S. used to be keen to make use of and what Iran may soak up whilst nonetheless staying within the struggle.
What the warfare may now not clear up used to be the nuclear dedication drawback. And this is going some distance again between the U.S. and Iran.
Iran adhered to the 2015 Joint Complete Plan of Motion, the landmark nuclear deal that limited Tehran’s nuclear program. The Global Atomic Power Company verified that Tehran stored uranium enrichment to a few.67% and its stockpile below 300 kilograms – a focus used to gas an influence reactor however some distance too low for a guns program.
However the U.S. walked away in 2018, and Trump later referred to as it “the worst deal ever” over its sundown clauses and on its silence on Iran’s ballistic missiles.

Iran returned to negotiations in 2025, and the U.S. and Israel bombed Iran whilst the ones talks had been nonetheless happening. In a similar way, in February 2026 the negotiations had been ongoing and a deal used to be inside of succeed in when Israel and the U.S. struck Iran – killing Perfect Chief Ali Khamenei and lead negotiator Ali Larijani.
The U.S. has demonstrated a report of reneging on its offers and breaking the negotiating procedure. Which is why Iran now insists on promises and calls for sanctions reduction ahead of signing a deal, and now not simply just right religion.
A state that in the past stored its commitments and used to be nonetheless bombed has little reason why to simply accept guarantees of reduction sooner or later. Because of this, I imagine the 60-day deferral is a window for Tehran to look at whether or not the U.S. and Israel will grasp the ceasefire on all fronts, together with Lebanon.
The 3rd drawback of indivisibility – when the object or factor in dispute can’t be break up or shared – is why the nuclear query is the toughest.
Maximum disputes may also be break up. Sanctions, for instance, may also be lifted by way of levels. Even a nuclear program may also be break up, which the arena noticed within the Joint Complete Plan of Motion deal, with centrifuges counted, enrichment capped and a stockpile metered.
What can’t be break up is the U.S. call for for 0 uranium enrichment and Tehran calling uranium enrichment a sovereign proper.
A deal, a warfare and a ceasefire
The 2015 nuclear deal additionally restricted Iran’s centrifuges – the machines that do the enriching – and positioned Iran’s nuclear program below essentially the most intrusive inspections, all in alternate for sanctions reduction.
The nuclear query used to be now not a part of the 2015 deal – it used to be the true deal.
All over the June 2025 negotiations with Iran, and once more in February 2026, the U.S. place used to be in regards to the nuclear program, however in the wrong way from the Joint Complete Plan of Motion. It used to be now not about limits however the general removal of Iran’s nuclear program.
In each rounds of talks in 2025 and 2026, Washington’s envoy, Steve Witkoff, demanded 0 enrichment and the dismantling of Natanz, Fordow and Isfahan – Iran’s 3 maximum necessary nuclear websites. Iran referred to as enrichment a sovereign proper and refused.
Each rounds of negotiations led to bombings.

The present deal to be signed on June 19 does now not put a cap on Iran’s enrichment, nor does it speak about the removal of its nuclear program. It ends the combating, reopens the Strait of Hormuz and consigns enrichment, the stockpile, missiles and Iran’s regional proxies to 60-day negotiations.
In a contemporary New York Instances interview, Trump mentioned he used to be in no rush to take away the near-bomb-grade gas nonetheless buried below the bombed websites. He claimed Iran would droop enrichment for 15 or two decades and enrich just for nonmilitary functions.
Within the Joint Complete Plan of Motion deal below President Barack Obama, the nuclear query used to be addressed the place 97% of Iran’s stockpile used to be shipped abroad and the cap used to be a verified reality.
As it doesn’t cope with any of those problems, the Trump deal is a ceasefire settlement, now not a nuclear settlement.
A expensive go back to the established order
Going again to the bargaining idea, we all know the warfare settled the tips drawback – it published what every facet would bear.
The dedication drawback stays. Neither facet can but make a promise the opposite believes, least of all an Iran whose negotiators had been killed.
And I imagine the indivisibility drawback is now worse. The query of 0 enrichment as opposed to a sovereign proper can’t be break up. The present 60-day deferral isn’t a answer. It’s the identical unsolved drawback with a clock hooked up.
The only factor that would alternate is American restraint. If Washington holds Israel from placing Iran and Lebanon, it might slowly rebuild its credibility that used to be destroyed by way of the 2 wars. And that could be a actual problem for the Trump management.
Even because the deal used to be being finalized, Israel struck Beirut, the type of motion that may derail any talks.
Personally, the 60-day window must be learn now not as the trail to a agreement however because the period or pause ahead of the following one fails.
I argued in April that this warfare would now not lead to a blank agreement however in a sequence of contested pauses. The deal to be signed on June 19 is the primary of them.
Iran emerges with its enrichment wisdom intact, its stockpile buried and contemporary reason why to imagine that just a nuclear weapon would have deterred the U.S.-Israel assault.
However Iran additionally is aware of that it stood its flooring and used to be in a position to strike U.S. bases and allies within the area. It has came upon leverage it didn’t up to now comprehend it held. The Strait of Hormuz has proved a greater deterrent than the nuclear bomb.
The strait is open, the oil is flowing, and the query the warfare used to be fought over sits precisely the place it all started. Hundreds of lives had been misplaced to reach again to sq. one. No person has received, although all sides will say they did.
