Iran should never have signed the 2015 nuclear deal, known as the JCPOA, Secretary of Iran's Supreme National Security Council Ali Shamkhani said.
In an interview with NBC News, Shamkhani said that there were people in Iran who felt that signing the JCPOA was a mistake.
Asked if he was one of those people, the official said, "Yes. … I'm just following the viewpoints of my nation, the people of Iran."
