Iran’s parliamentary speaker has said that a possible US pullout from the nuclear deal will lead to more unity among Iranians. Ali Larijani said that “this loyalty in nuclear issue will [encourage] the great Iranian nation to continue on the path of the Islamic Revolution firmly behind the leadership of its supreme leader.” US President Donald Trump tweeted late on Monday night to say that he plans to announce his decision about whether to pull America out of the deal on Tuesday. Iran’s President Hassan Rouhani acknowledged the country could “face some problems” ahead of Trump’s planned announcement. At a meeting at a petroleum expo in Tehran on Tuesday, Rouhani said: “It is possible that we will face some problems for two or three months, but we will pass through this.”
