“They will never have a nuclear weapon, and they understand it,” Trump told voters in Tennessee. In the Fox interview, Trump said the United States and Iran had held “some very good talks”. “Well, that’s all we discussed because they’ll never have a nuclear weapon, they understand that.” “We took out their nuclear sites, and we’ll have to take out Pickax if we don’t make a deal,” Trump said. Iran and six world powers concluded a nuclear agreement in 2015 that restricted Tehran’s nuclear programme in exchange for sanctions relief.
