Studying and explaining the managerial style of Hazrat Ayatollah Seyyed Ali Khamenei in the case of the core of the Islamic Republic of Iran

Ayatollah Seyyed Ali Khamenei (the Supreme Leader) in the dispute over the Islamic Republic of Iran's peaceful nuclear program and the long-term diplomatic engagement with the West, which eventually led to the formation of the so-called Borjam nuclear deal. They played an effective and decisive leadership role. The present study seeks to answer the main question, on what basis did the Supreme Leader of the Revolution manage the conflict over Iran's nuclear program and the processes leading to the nuclear deal - Borjam - and the so-called post-Borjam period? The hypothesis that has been tested in answer to this question is that His Holiness has guided the above process by combining the two models of hard leadership and soft leadership in the form of a new model of intelligent leadership style. He has implemented this process in two ways: institutional-structural (hard) and non-institutional (soft). The findings of the article show that institutional-structural management has been implemented through the Islamic Consultative Assembly, the Supreme National Security Council, the formation of the Borjam Supervision Team, and military institutions. The non-institutional management model also emphasizes the fundamental role of the people, avoiding excesses in the UN Security Council, clarifying the nature of the other side, encouraging negotiations, inviting national unity, emphasizing the need to fully lift sanctions, adopting strategic rationality and Ongoing monitoring of the other side's movements, resolving internal strategic weaknesses, determining the mission of the government and the negotiating team, and requiring the continuation of the nuclear industry have been implemented.
