Iranian president warns US it will regret quitting nuclear deal ‘like never before’
Donald Trump faces harsh words from Hassan Rouhani as British Foreign Secretary Boris Johnson appeals to the US president not to end the agreement
Tehran — Iranian President Hassan Rouhani warned that if the US quits the nuclear deal then Washington will regret it "like never before", as British Foreign Secretary Boris Johnson appeals to US President Donald Trump not to end the agreement.
Trump has threatened to withdraw from the agreement when it comes up for renewal on May 12, demanding his country’s European allies "fix the terrible flaws" or he will re-impose sanctions.
"If the US leaves the nuclear agreement, you will soon see that they will regret it like never before in history," reformist Rouhani said in a televised speech in northwestern Iran.
"Trump must know that our people are united, the Zionist regime [Israel] must know that our people are united," Rouhani said.
"Today all [Iran’s] political factions, whether they be from the right, the left, the conservatives, reformers and moderates are united," he added.
The nuclear deal was struck in 2015 between Iran and Britain, China, France, Germany, Russia and the US, then led by Barack Obama.
Under the pact, sanctions were eased in return for a commitment not to pursue a nuclear bomb, but Iran says it is not reaping the rewards despite complying with the deal.
A senior Israeli official said on Sunday that Trump had not informed Israel of whether it would withdraw from the agreement.
"In effect, I don’t know what Trump will decide because he hasn’t told me," the official said on condition of anonymity, making clear Israel had not yet been told of Trump’s decision.
Trump has consistently complained about the agreement, citing perceived flaws including "sunset" provisions lifting some nuclear restrictions from 2025.
In an attempt to salvage the deal, French President Emmanuel Macron has recently pushed to extend its scope to address this issue, as well as the absence of any limits on Iran’s conventional missile capabilities and Tehran’s role in the region.
Britain’s Johnson would begin a two-day visit to Washington on Monday, with the nuclear deal among issues on top of the agenda, the Foreign Office said.
He is due to meet US Vice-President Mike Pence, national security adviser John Bolton and congressional foreign policy leaders.
He said Britain — which remains committed to the agreement — the US and Europe were "united in our effort to tackle the kind of Iranian behaviour that makes the Middle East region less secure — its cyber activities, its support for groups like Hezbollah, and its dangerous missile programme".
Johnson wrote in an opinion piece for the New York Times that the deal had weaknesses but these could be addressed given time.
"Indeed at this moment Britain is working alongside the Trump administration and our French and German allies to ensure that they are," Johnson wrote.
He said he saw no advantage in losing the "handcuffs" the deal imposed on Iran’s nuclear ambitions and only Tehran would benefit from exiting the deal.
"At this delicate juncture, it would be a mistake to walk away from the nuclear agreement and remove the restraints that it places on Iran," Johnson wrote.
"I believe that keeping the deal’s constraints on Iran’s nuclear programme will also help counter Tehran’s aggressive regional behaviour. I am sure of one thing: every available alternative is worse. The wisest course would be to improve the handcuffs rather than break them."
Iran has said it will not renegotiate the nuclear agreement.
Iran’s support for Syrian President Bashar al-Assad, via the Lebanese armed group Hezbollah in Syria’s civil war, and its backing for Shiite Huthi rebels in Yemen have added to frictions between Tehran and western powers.
Rouhani vehemently reiterated his country’s opposition to curtailing its non-nuclear missile capabilities, in his speech on Sunday.
Tehran "will build as many missiles and weapons as needed" for its defence, he said.
"We are honouring our commitment, but we are telling the whole world we will not negotiate with anyone about our weapons and our defence."
Iran’s president also said that while he was open to discussing the country’s regional role, he would not abandon what he described as its fight "against terrorism".
"We want to talk to the world so that our region is safe" but "we will not allow you to create a new Daesh", he said, using an Arabic term for the Islamic State (IS) group.
While Rouhani did not elaborate on this point, Iran’s ally the Syrian government has consistently referred to all armed opponents as "terrorists" and accused the West of facilitating terrorism.
Iran has always denied it sought a nuclear weapon, insisting its atomic programme was for civilian purposes.
Rouhani did not specify how Iran would react if the US pulls out of the 2015 deal.
But he said he had given "the necessary orders", notably to Iran’s Atomic Energy Organisation, in anticipation of Trump’s decision.
As the May 12 US decision point nears, Iranian leaders have shuffled between placatory and hawkish comments, although the hardliners have taken a uncompromising stance.
On Thursday Ali Akbar Velayati, the foreign policy adviser to Iran’s supreme leader Ayatollah Ali Khamenei, warned Tehran would quit the nuclear deal if the US withdrew.
