In recent years, numerous analyses have been published on the increasing influence of the IRGC within the Iranian regime. Nevertheless, the rise in the power of the military should not overshadow the fact that in the Islamic Republic, not only the paramount position of supreme leader, but also many other key roles are held exclusively by clerics.

This system was designed to ensure the loyalty of key officials, but over time has given rise to growing concerns over the reliability of the next generation of clerics and the transfer of power.
