<p class="title rtejustify">Iranian President Hassan Rouhani warned that if the United States quits the nuclear deal then Washington will regret it "like never before", as British Foreign Secretary Boris Johnson scrambles to save the agreement during talks with the Trump administration Monday.</p>.<p class="bodytext rtejustify">US President Donald 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.</p>.<p class="bodytext rtejustify">"If the United States 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.</p>.<p class="bodytext rtejustify">"Trump must know that our people are united, the Zionist regime (Israel) must know that our people are united," Rouhani said.</p>.<p class="bodytext rtejustify">"Today all (Iran's) political factions, whether they be from the right, the left, the conservatives, reformers and moderates are united," he added.</p>.<p class="bodytext rtejustify">The nuclear deal was struck in 2015 between Iran and Britain, China, France, Germany, Russia and the United States, then led by Barack Obama.</p>.<p class="bodytext rtejustify">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.</p>.<p class="bodytext rtejustify">A senior Israeli official said Sunday that Trump had not informed Israel of whether it will withdraw from the agreement.</p>.<p class="bodytext rtejustify">"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.</p>.<p class="bodytext rtejustify">Trump has consistently complained about the agreement, citing perceived flaws including "sunset" provisions lifting some nuclear restrictions from 2025.</p>.<p class="bodytext rtejustify">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.</p>.<p class="bodytext rtejustify">Britain's Johnson will on Monday begin a two-day visit to Washington, with the nuclear deal among issues on top of the agenda, the Foreign Office said.</p>.<p class="bodytext rtejustify">He is due to meet US Vice President Mike Pence, National Security Advisor John Bolton and Congressional foreign policy leaders.</p>.<p class="bodytext rtejustify">He said Britain -- which remains committed to the agreement -- the United States 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".</p>.<p class="bodytext rtejustify">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.</p>.<p class="bodytext rtejustify">Rouhani vehemently reiterated his country's opposition to curtailing its non-nuclear missile capabilities, in his speech on Sunday.</p>.<p class="bodytext rtejustify">Tehran "will build as many missiles and weapons as needed" for its defence, he said.</p>.<p class="bodytext rtejustify">"We are honouring our commitment, but we are telling the whole world we will not negotiate with anyone about our weapons and our defence."</p>.<p class="bodytext rtejustify">Iran's president also said that while he is open to discussing the country's regional role, he would not abandon what he described as its fight "against terrorism."</p>.<p class="bodytext rtejustify">"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 group.</p>.<p class="bodytext rtejustify">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.</p>.<p class="bodytext rtejustify">Iran has always denied it sought a nuclear weapon, insisting its atomic programme was for civilian purposes.</p>.<p class="bodytext rtejustify">Rouhani did not specify how Iran would react if the US pulls out of the 2015 deal.</p>.<p class="bodytext rtejustify">But he said he had given "the necessary orders", notably to Iran's Atomic Energy Organisation, in anticipation of Trump's decision.</p>.<p class="bodytext rtejustify">As the May 12 US decision point nears, Iranian leaders have shuffled between placatory and hawkish comments, although the hardliners have taken an uncompromising stance.</p>.<p class="bodytext rtejustify">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 United States withdraws.</p>
