John Kerry knows that he has no influence over POTUS with regard to his decision on the Iran Deal, so what is Kerry doing in Iran? He's discussing the path forward post-POTUS decision.

Otherwise his visit doesn't make any sense and if Kerry wanted to influence the deal he would talk to POTUS, not Iran.

So what do we think Kerry is planning for the cabal? What's he whispering in Iran's ear? Blackmail reveal?
