President Donald Trump announced he was pulling the United States out of the "defective" multinational nuclear deal with Iran
Washington (AFP) - President Donald Trump pulled the United States out of a landmark deal curbing Iran's nuclear program and reimposed crippling sanctions on Tuesday, defying European pleas and prompting international outcry.
Trump poured scorn on the "disastrous" 2015 accord, describing it as an "embarrassment" to the United States that does nothing to contain Iran's nuclear ambitions.
"The United States will withdraw from the Iran nuclear deal," Trump said in an address to the nation from the White House.
Slapping aside more than a decade and a half of careful diplomacy by Britain, China, France, Germany, Iran, Russia and past US administrations, Trump called for a "new and lasting deal."
That grand bargain, he said, would have to include not just deeper restrictions on Iran's nuclear program, but on its ballistic missiles and support for militant groups across the Middle East.
"We cannot prevent an Iranian nuclear bomb under the decaying and rotten structure of the current agreement," he claimed.
"We will not allow American cities to be threatened with destruction and we will not allow a regime that chants 'Death to America' to gain access to the most deadly weapons on Earth."
It remains far from clear if the international community, or Iran, will play along.
Iran's President Hassan Rouhani -- whose standing at home now risks being undermined by the deal's collapse -- was furious, accusing Trump of "psychological warfare."
Rouhani said Iran could resume uranium enrichment "without limit" in response to Trump's announcement, but that it would discuss its response with other parties to the deal before announcing a decision.
Trump's onerous demands and his warning that Iranians deserve better than their current "dictatorship" will only heighten suspicions his ultimate goal is regime change.
"If the regime continues its nuclear aspirations, it will have bigger problems than it has ever had before," he warned.
- 'We're out' -
Hawkish US officials believe that after 38 years in power, Iran's clerical regime is substantially weakened by domestic economic pressure, changing demography, public demonstrations, and costly foreign military adventures.
The decision marked a stark diplomatic defeat for Europe, whose leaders, repeatedly and in person, begged the mercurial US leader to think again.
In a joint statement, Germany's Angela Merkel, Britain's Theresa May and France's Emmanuel Macron voiced their "regret and concern" at Trump's decision.
European firms doing business in Iran now have a six month deadline to wind up investments, or risk US sanctions, Trump's hawkish advisor John Bolton said, while ruling out talk of reconsideration.
"We're out of the deal. We're out of the deal. We're out of the deal," he said.
And Treasury Secretary Steven Mnuchin made it clear that Washington was acting "under both our primary and secondary sanctions authorities," meaning that European firms with investments or operations in the United States could be targeted if they continue to trade with Iran.
In a sign of the depth of European displeasure, plans are already being drawn up in Brussels to introduce measures blocking US sanctions, an extremely rare move against an allied government.
But Bolton said that cooperation with Europe on Iran was not over, and that Trump had waited until the last minute -- "just before the speech, really" -- to make his final decision, listening to different views on the issue, including from American allies.
The US will "work with the Europeans and others not only on the nuclear issue but on Iran's ballistic missile development, its continuing support for terrorism and its military activities that jeopardize our friends," Bolton told Fox News.
- 'Bold decision' -
While Iran's arch foes in Israel and Saudi Arabia welcomed Trump's decision, signatories to the existing deal vowed to plow ahead without the United States.
The European Union's chief diplomat Federica Mogherini, who helped oversee the accord, insisted it was "delivering on its goal which is guaranteeing that Iran doesn't develop nuclear weapons."
"The European Union is determined to preserve it," she added.
Trump's decision offers him a domestic political victory, fulfilling a longstanding campaign promise and underscoring his no-nonsense political brand.
But the long term impact for American foreign policy and for the Middle East was less clear.
Former US president Barack Obama -- whose administration inked the deal -- made a rare public criticism of his successor, describing Trump's decision to abandon the Iran nuclear deal as "misguided" and a "serious mistake."
"The consistent flouting of agreements that our country is a party to risks eroding America's credibility, and puts us at odds with the world's major powers."
And Russia's foreign ministry said it is "deeply disappointed by the decision of US President Donald Trump to unilaterally refuse to carry out commitments" under the deal.
In contrast, Israel's Prime Minister Benjamin Netanyahu, who last week released a trove of intelligence on a pre-2003 Iranian plan to develop a nuclear weapon which Trump cited approvingly in his speech, was overjoyed.
"Israel fully supports President Trump's bold decision today to reject the disastrous nuclear deal," Netanyahu said, in a televised address.
