Iran is entitled to gain benefits from the 2015 nuclear deal and no one can roll back the positive results of the accord, Iranian President Hassan Rouhani said here on Saturday."In the nuclear negotiations and the deal, we gained advantages that are irreversible. No one can reverse them, neither Mr. Trump nor anyone else," Xinhua cited Press TV that quoted Rouhani as saying."In negotiation, we showed that we are not just strong at war, but we are also strong at making peace," he said, adding that Iran established its right to peaceful nuclear energy during the talks and "this victory is not reversible."The Iranian president said that the US was claiming it has been shortchanged in the deal, "which is of course wrong, because the deal has been based on a win-win framework."The nuclear deal, known as Joint Comprehensive Plan of Action (JCPOA), reached between Iran and six world powers of Britain, China, France, Germany, Russia and the US in July 2015, now faces the risk of collapse amid a fallout between Washington and Tehran.Trump called the Iran nuclear deal, reached during former US President Barack Obama's administration, "an embarrassment" for the country.Rouhani has said that his country will not be the first to violate the agreement, but will respond "decisively and resolutely" to any violation by any party."It will be a great pity if this agreement were to be destroyed by rogue newcomers to the world of politics," Rouhani told the UN General Assembly, in response to Trump's attack.
