A woody betwixt the US and Iran is "scheduled to get signed" connected Sunday, President Donald Trump has said - though Tehran has expressed scepticism astir the timing.
Prior to Trump's comments connected Saturday afternoon, Iran's overseas ministry spokesperson Esmaeil Baghaei said: "We volition person to hold and spot astir the nonstop day of the signing of the memorandum of understanding, though it volition not beryllium tomorrow."
Either way, the statement could reopen the Strait of Hormuz successful instrumentality for the US lifting its blockade connected Iranian shipping.
While officials accidental the woody volition besides pb to the demolition and removal of Iran's enriched uranium stockpiles - a cardinal constituent of atomic weapons - the method details are inactive being worked out.
If and erstwhile an statement is signed, it volition apt beryllium judged against the 2015 atomic statement negotiated by the Obama medication and different nations, which was abandoned by Trump during his archetypal term.
Trump's 'nuclear dust' plans
Uranium is simply a people occurring radioactive element. It contains peculiar properties that tin beryllium utilized to substance atomic powerfulness plants, but besides assistance make atomic weapons.
However, it needs to beryllium "enriched" first, a process that involves expanding the attraction of uranium-235 isotope - the indispensable constituent of atomic fuel.
Since the warfare started connected 28 February, Trump has repeatedly said Iran needs to surrender its stockpiles.
He reiterated this successful an interrogation with NBC connected 7 June, saying: "If we marque a woody present we're friendly, we'll each spell together. It'll beryllium our equipment. We'll instrumentality it retired and destruct it, whether it's onsite oregon whether we instrumentality it offsite."

Trump has said Iran needs to manus implicit its "nuclear dust"
The destiny of Iran's uranium stockpile was cardinal to the 2015 atomic statement - the Joint Comprehensive Plan of Action (JCPOA) - which imposed strict limits connected Iran's enrichment activities.
"The fig 1 contented that was moving astatine that clip was whether Iran was going to spell for gathering a atomic weapon", erstwhile JCPOA pb negotiator Baroness Ashton told BBC Verify.
In exchange, the US agreed to assistance sanctions against Iran, including connected oil, commercialized and banking.
Under the deal, Iran could lone support a tiny magnitude of monitored, low-enriched uranium.
Low-enriched uranium - typically 3-5% purity - is capable to nutrient reactor substance required for a atomic powerfulness station, but weapons-grade uranium needs to beryllium astatine slightest 90% enriched.
The breakdown of the 2015 deal
"The woody was remarkably successful," argues Kelsey Davenport from the Arms Control Association (ACA), a nationalist nonpartisan rank organisation.
"Any determination to atomic weapons, immoderate deviation from the JCPOA's presumption would person been detected," Davenport told BBC Verify, noting that some the IAEA and US quality repeatedly assessed Iran was complying.
However, erstwhile President Trump announced the US withdrawal from the statement successful May 2018, helium called it a "horrible, one-side woody that should never, ever person been made".
He said it failed to code Iran's ballistic rocket programme, that the inspection requirements lacked mechanisms "to prevent, detect, and punish cheating" and that Israeli quality showed Tehran's "history of pursuing atomic weapons".
Jacob Olidort, main probe serviceman astatine the America First Policy Institute, says Trump was right.
"All of these issues were wholly pushed to the sidelines, wholly deprioritised and not included successful the arrangement", helium told BBC Verify.
Baroness Ashton, who negotiated the woody connected behalf of the UN Security Council, rejects this.
"There was ever a disapproval that we should person covered each benignant of things. But the captious question was, 'Could we forestall immoderate fearfulness that Iran was going to physique a atomic weapon?' And we did that."
"There was plentifulness of accidental afterwards to speech astir different issues, ballistic missiles, drones etc. And so the Trump medication successful its archetypal word could person done that," she adds.
"If President Trump felt that the woody was inadequate, past the reply was to physique connected it, not to rip it up."
Olidort says the time-limited quality of the woody meant Iran could person yet pursued a atomic weapon.
"It was ever made explicit successful the woody that the presumption of the woody would expire… The sunset clauses successful effect nullify their effectiveness," helium argues.
Davenport says that due to the fact that immoderate limits connected the uranium enrichment level and stockpile size were lone acceptable for 15 years, "by January 2031, Iran could theoretically grow its enrichment programme".
But galore different features were permanent, including IAEA safeguards, she said, adding: "There was inactive a full big of different provisions that would person provided assurance that immoderate determination successful that absorption [towards a atomic weapon] would person been rapidly detected".
Money has been a recurring taxable of Trump's criticism, taking purpose astatine erstwhile President Barack Obama aggregate times.
Under the JCPOA, Iran gained entree to billions of dollars successful antecedently frozen assets and benefited from the lifting of planetary sanctions.
Baroness Ashton, however, says authorisation alleviation was a indispensable request to unafraid the agreement.
"If you authorisation idiosyncratic due to the fact that they're doing immoderate behaviour and they alteration the behaviour, past by explanation the authorisation cannot stay."
Olidort argues lifting sanctions helped Iran money its accepted limb programmes successful summation to its atomic one.
In the years aft the US withdrew from the agreement, Iran began to accelerate its uranium enrichment programme.
The US and Israel attacked Iran's facilities successful June 2025, which American officials said importantly acceptable backmost the imaginable of Tehran gathering a atomic weapon.
The caput of the IAEA, Rafael Grossi, told the Associated Press successful April that the bulk of Iran's highly enriched uranium (roughly 200kg; 440lbs) was apt located successful underground tunnels astatine its Isfahan atomic complex, astir 273 miles (440km) southbound of Tehran.
Grossi said inspectors had been incapable to verify the tract since the struggle began.
"We haven't been capable to inspect oregon to cull that the worldly is determination and that the seals - the IAEA seals - stay there," helium said.
Grossi added the the IAEA besides wanted to inspect Iran's atomic facilities astatine Natanz and Fordo.
In a Truth Social station past month, Trump declared his envisaged woody would beryllium "far better" than the JCPOA.
While the nonstop presumption are unclear, Davenport argues Iran volition expect to payment economically from immoderate statement and that Trump whitethorn effort to defy immoderate examination with the JCPOA fixed his past disapproval of sanctions relief.
"Iran is not going to hold to a woody that does not see sanctions alleviation and assets oregon entree to its frozen assets. Tehran has made precise wide that those are cardinal issues", she says.
Trump volition apt privation to amusement helium secured concessions that Obama could not, she adds. That could see a impermanent suspension of enrichment and the disposal of Iran's existing stockpile.
"He's going to constituent to 2 factors to assertion victory, that helium cleaned up a messiness that he'll accidental accelerated nether Biden and helium got what Obama couldn't, which was a multi-year suspension".
However, Davenport besides points retired that Iran's atomic programme is precise antithetic from the 1 negotiators faced successful 2015 - owed to the evident demolition of astir of its enrichment capacities - making it hard to gully nonstop examination with the JCPOA.
Olidort believes the US is negotiating from a presumption a spot and does not spot a woody being weaker than the JCPOA.
Iran "is successful a overmuch much weakened authorities from... its capabilities perspectives, but besides the authorities of antithetic proxies successful the region".
While the details of immoderate statement stay unclear, Baroness Ashton argues that subject unit unsocial is improbable to unafraid a lasting settlement.
"All I tin accidental is successful my experience, the mode that negotiations enactment is that radical person to consciousness that they've got capable to marque it worthwhile participating successful that negotiation".
