This ADG Consult Insight Paper examines Hezbollah’s evolution from a Lebanese Shiite resistance movement into a powerful political, social and military organisation operating alongside—and frequently beyond—the authority of the Lebanese state. It assesses Hezbollah’s leadership, ideology, relationship with the Islamic Revolutionary Guard Corps (IRGC), current military position, Israeli pressure, the role of the Lebanese Armed Forces and the increasingly serious debate over disarmament.
The paper argues that while Hezbollah’s Lebanese political and social constituency would survive major political change in Iran, the organisation’s defining role as an autonomous strategic military force is fundamentally dependent on Iranian sponsorship. If IRGC rule in Tehran ends and a successor government abandons the revolutionary external-support model, Hezbollah would face progressive financial, military, ideological and organisational decline. The likely result would not be its immediate disappearance, but its eventual transformation, fragmentation or absorption into Lebanon’s political and state structures—creating a historic opportunity for Beirut to restore exclusive national authority over war, peace and armed force.
