VIENNA (Dispatches) -- Russia’s lead negotiator at the Vienna talks said Sunday the aim of the negotiations is to restore the 2015 deal in its original form, rather than adding or removing anything to and from the historic agreement that was reached between Iran and six world powers. “The agreed aim of the #ViennaTalks is to restore the #JCPOA in its original form. Nothing more and nothing less,” Mikhail Ulyanov tweeted, referring to the nuclear deal by its official acronym.
