Who determines Iran’s fighting and negotiating position amid US threats?

Negotiations aimed at preventing a further escalation between Iran and the United States have stalled, drawing attention to the power of Iran’s security and military establishment. President Masoud Pezeshkian said Supreme Leader Mojtaba Khamenei had granted his government certain powers to negotiate, but gave no details. Since US-Israeli strikes on February 28 killed Ali Khamenei and other senior officials, influence has increasingly shifted to Islamic Revolutionary Guard Corps commanders and other security officials. Tehran has put forward a seven-point plan demanding an end to the war and the reopening of the Strait of Hormuz.
