 But the country's supreme leader, Ayatollah Ali Khamenei, was sceptical, saying he did not trust Britain, France or Germany, and would need "guarantees" before continuing the nuclear deal. In his address on Tuesday, President Trump called the nuclear accord - or Joint Comprehensive Plan of Action (JCPOA) as it is formally known - a "horrible, one-sided deal that should have never, ever been made". He also said Trump's remarks threatened Iran's people and its theocratic government. The JCPOA saw Iran agree to limit the size of its stockpile of enriched uranium - which is used to make reactor fuel, but also nuclear weapons - for 15 years and the number of centrifuges installed to enrich uranium for 10 years. Iran insists its nuclear programme is entirely peaceful, and its compliance with the deal has been verified by the International Atomic Energy Agency (IAEA), who on Wednesday again said Iran was honouring its commitments. The six major powers involved in the nuclear talks with Iran were in a group known as the P5+1: the UN security council’s five permanent members – China, France, Russia, the UK and the US – and Germany. US National Security Adviser John Bolton is reported as saying that European companies doing business in Iran will have to stop doing so within six months or face US sanctions. In a statement, President Hassan Rouhani said: "If we achieve the deal's goals in co-operation with other members of the deal, it will remain in place."
– President Trump's decision to pull the US from the Iran nuclear deal drew a fiery response from conservative Iranian lawmakers Wednesday—during the opening session of the country's parliament, they burned a paper American flag and the text of the 2015 deal, chanting "Death to America." But they were scenes of celebration, not anger, the Guardian reports. Hardliners in Iran view the US pullout as an opportunity to gain power over moderates who pushed for the 2015 deal, analysts say. The commander of Iran's Revolutionary Guards issued a statement Wednesday congratulating the country over the US move, saying it "was proved once more that US isn't trustworthy in regards its commitments." Iran's supreme leader, Ayatollah Ali Khamenei, challenged Trump over the withdrawal Wednesday, saying "You cannot do a damn thing," CNBC reports. But while hardliners are calling for the country to immediately restart its nuclear program, Iranian President Hassan Rouhani says the deal can still be salvaged. He announced late Tuesday that he will send his foreign minister to visit the other signatories: China, France, Germany, Russia, and the UK. Jean-Yves Le Drian, France's foreign minister, said Wednesday that "the deal is not dead," the BBC reports. "There's an American withdrawal from the deal but the deal is still there," he said. Russian officials said they were "deeply disappointed" by Trump's decision, though it was cheered by Tehran foes Israel and Saudi Arabia.
