US Vice President JD Vance is being considered a key player in potential Iran talks, as Tehran indicates it wants to directly engage him in negotiations. The White House insists only President Trump can decide who negotiates for the US, not Tehran's. This position reflects Vance's growing influence inside the administration and Iranian officials' belief that he represents a different kind of American interlocutor. While Vance has been critical of past Middle East interventions, he has publicly backed President Trump on the Iran war. Negotiations between Iran and the US are currently under way, but any agreement would require approval from Iran’s supreme leader.
