A frequently asked question in Lebanon has been how the Iranian nuclear agreement might affect Iran's ties with Hezbollah. But party officials and independent Lebanese observers paint a picture of an unbreakable bond between the two. They believe the geopolitical dynamics taking shape in the region and beyond, now that the Joint Comprehensive Plan of Action is being implemented, further strengthen Hezbollah.

Anyone who thinks Iran's return to the national stage will decrease its support for Hezbollah "doesn’t know how Iran thinks,” a Hezbollah official told Al-Monitor, noting that the group is widely considered to be Tehran’s staunchest ally.

Speaking from his office in Dahiyeh in southern Beirut, an area commonly referred to as Hezbollah’s stronghold, the official, who asked not to be named, underscored that “Hezbollah is more than just an ally for Iran.” The relationship is similar to “that between father and son,” he said, going on to emphasize the ideological factor by saying that any success for Iran means success for Hezbollah and for the velayat e-faqih.

The official added that Hezbollah had credible information that Iran did not agree to discuss any issues other than the nuclear dossier during its talks with six world powers, citing this as evidence that Tehran will not budge regarding its support for the Lebanese movement.
