Ongoing US-Iran military conflict since February 2026, including strikes that killed prior Supreme Leader Ali Khamenei and reportedly injured Mojtaba Khamenei, has shaped diplomacy. Mojtaba, appointed in March, has issued statements but made no public appearances, prompting Trump comments on his health and injury status. Recent September UN talks involved US and Iranian officials, including indirect channels, yet Trump rejected Iranian proposals on sanctions relief and the Strait of Hormuz, with both sides signaling readiness for further negotiations or escalation ahead of US midterms. Direct leader-to-leader contact remains absent amid intermediary efforts and mutual demands.
