The Islamic Revolutionary Guard Corps (IRGC) has gained significant control over Iran's decision-making, sidelining civilian leaders and operating autonomously under Supreme Leader Mojtaba Khamenei. Key figures like IRGC commander Ahmad Vahidi and Parliament Speaker Mohammad Bagher Ghalibaf are now making crucial military and political decisions. The IRGC, established in 1979, has evolved into a powerful military and economic entity, influencing both domestic and international affairs. Recent leadership changes and the deaths of key commanders have further solidified its position, leading to a shift towards an IRGC-centric power structure in Iran.
