As the negotiations proceeded in Geneva, the Israeli premier, Binyamin Netanyahu, warned against any agreement that left the Iranian nuclear programme in place. He said: “I believe adopting the proposals is a mistake of historic proportions. They must be rejected outright.”
Asked about Netanyahu’s comments, Zarif said: “I don’t think he’s an authority on mistakes because he’s been making mistakes for his entire life. He’s been calling the Iranian programme six months away from a nuclear weapon since 1991, so I don’t consider him a credible authority.”
