In light of the escalating tensions between the United States and Iran, with diplomatic efforts continuing in Oman, Ali Khamenei, the Supreme Leader of Iran, has appointed Ali Larijani as the acting head of state in the event of his assassination. This choice highlights Khamenei's concern over the country's stability amidst external pressures and domestic unrest. Larijani, a seasoned national security official at 67 years old, is seen as a potential successor to Khamenei following protests that erupted in Iran in January following threats from the US.

Ali Larijani has been described as a deeply enigmatic figure who operates largely in the shadows of Iranian politics. His dual identity allows him to present himself as either a reformist or a hardliner, depending on the situation, which raises questions about his true intentions and policies. With a background in government and security, Larijani's appointment signals a significant shift in Iran's political dynamics as the country navigates its complex relationships with both domestic opposition and foreign adversaries.

As Iran seeks to strengthen ties with Russia, particularly under Vladimir Putin's leadership, Larijani's role could prove pivotal in shaping Iran's response to ongoing geopolitical challenges. His ability to maneuver in a shifting political landscape will not only influence Iran's internal affairs but also its external relations, particularly within the context of US-Iran tensions and Iran's alignment with Russia. This raises implications for regional security and international diplomatic relations, affecting not just Iran and the US, but also the broader Middle Eastern geopolitical landscape.
