President Trump has given Iran's warring factions a short window to unite, or the ceasefire he extended ends. Negotiators believe a deal to end the war and address Iran's nuclear program is still achievable, but worry they may not have anyone in Tehran empowered to say yes. Supreme Leader Mojtaba Khamenei is barely communicating with the IRGC generals, who have been at odds with Iran's civilian negotiators over strategy since the March assassination of Ali Larijani. The split emerged when Foreign Minister Abbas Araghchi announced the reopening of the Strait of Hormuz, and Iran refused to implement it and publicly attacked him. The White House has been frustrated by the division, particularly as Vice President Vance had planned to lead a second round of peace talks.
