One year after the signing of the comprehensive nuclear deal between Iran and the six world powers, a number of obstacles surrounding the landmark deal remain, most notably the remaining US sanctions on Iran that were not part of the deal. While Iran's top nuclear negotiators have been making media rounds selling the achievements of the deal to the Iranian public, which will be heading for voting booths in 10 months to elect a president, the delivery of the Russian S-300 long-range surface-to-air missile defense system stands out as one particular obstacle that has been removed as a result of the nuclear deal.
According to the Tasnim News Agency, the missiles for the S-300 have been shipped to Iran. In April, Iran's Foreign Ministry announced that the first phase of the delivery of the missile defense system had begun, just four months after implementation of the nuclear deal and one year after Russian President Vladimir Putin lifted the ban on the sale of the system as the result of the interim deal in the nuclear negotiations. On July 1, Brig. Gen. Farzad Esmaili, commander of the Khatam al-Anbia Air Defense Base, said the S-300 missile defense system would be fully operational by March 2017.
