One of the most popular American negotiators in Iranian social media was US Energy Secretary Ernest Moniz. The Massachusetts Institute of Technology (MIT) professor emeritus and former director of the MIT Laboratory for Energy and the Environment joined the nuclear talks between Iran and five permanent members of the UN Security Council plus Germany (P5+1) to discuss the technical aspects of the nuclear deal with the head of Iran’s Atomic Energy Organization, Ali Akbar Salehi.

In an interview with an Iranian newspaper, Salehi spoke about the negotiations and his relationship with Moniz. Just as Moniz was picked to lead the technical negotiations due to his nuclear expertise, Salehi, an MIT graduate, is one of the few individuals to have held important positions for three consecutive administrations — a sign that he has the trust of Supreme Leader Ayatollah Ali Khamenei.

Salehi first denied accusations that former hard-line nuclear negotiator Saeed Jalili was not a serious negotiator. Salehi was Iran’s foreign minister at the time and said that when he was at the meetings with the Supreme National Security Council, Jalili’s negotiating positions were in line with the country’s positions and that “he did not go rogue.”

According to Salehi, the reason for the deadlock during that time was the differences among the P5+1. Specifically, the EU3 (France, United Kingdom and Germany) saw their positions and interests separate from the E3 (US, Russia and China). He said that even when European Union Chief Catherine Ashton reached a point of agreement with Iran on one issue, one country would oppose it and throw everything off. This is why Iran agreed to bilateral talks with the United States in Oman.
