Kian Tajbakhsh, an ex-political prisoner, was launched from Iranian jail in 2015 and is now a professor at NYU. He warns that in the Middle East what the negotiators are saying in personal in English is meaningless and it is just what they are saying in their very own language in public that’s truthful. Tajbakhsh says Iran is an skilled in utilizing ambiguity for its personal functions and that will occur in backchannel conversations about the settlement.
