There is a 100% link. Hezbollah was created by the Revolutionary Guards. As I said, Hossein Dehghan, who was the former defence minister of former so-called reformist president Hassan Rouhani in the late 1980s, wrote the Hezbollah charter. The Islamic Republic via the IRGC has been the biggest supporter for Hezbollah ideologically in terms of training, militarily in terms of the supply of arms, and in terms of logistics and coordination.
Hezbollah is the Islamic Revolutionary Guard Corps' proxy. It is Iran's proxy group. The group vows allegiance, complete and absolute, to Ayatollah Khamenei as their supreme leader as well as leader of the Islamic world.
