Iran's new president, Massoud Pezeshkian, traveled to the U.S. last week to present a moderate, rational face of the regime to the world. He claimed in a speech at the United Nations General Assembly (UNGA) that Iran did not want to be a source of instability in the Middle East, and only wanted peace. The president spoke of a 'new era of cooperation' with the West and made an overture to engage in nuclear talks. Experts say Iran is sending Pezeshkian out to project a moderate front on the global stage - but behind the scenes he holds little power. Supreme Leader Ayatollah Ali Khameini pulls all the strings.
