Iran has entered a new political phase as Mojtaba Khamenei has been appointed the country's new Supreme Leader following the death of Ali Khamenei during the ongoing conflict involving Israel and the United States. The decision was taken by Iran's Assembly of Experts, marking a historic leadership transition in the Islamic Republic. The appointment comes at a time when tensions in the Middle East remain extremely high. US President Donald Trump has already issued sharp warnings over Iran's leadership choice, saying he is unhappy with Tehran's decision and cautioning that the new leader may not "live in peace" if tensions escalate further. Mojtaba Khamenei, long viewed as an influential figure behind the scenes, has strong ties with Iran's powerful security institutions, including the Islamic Revolutionary Guard Corps. His elevation now places him at the center of one of the most critical moments in Iran's modern history, as the country navigates war pressures, international sanctions, and internal power struggles.
