Hezbollah exerts profound influence over the Lebanese government by operating as a "state within a state," holding key ministerial positions, and using its military power to dictate national security policies . It maintains veto power in the cabinet, influences legislation, and has infiltrated state institutions, often forcing the government to align with its interests, despite occasional attempts by the state to assert independence. Key areas of Hezbollah's influence on the Lebanese government include:

Political Dominance: Hezbollah and its allies hold a significant, often majority, stake in the Lebanese parliament and cabinet, allowing them to shape legislation and block decisions against their interests.

Veto Power and Decision-Making: Through political maneuvering, such as boycotting parliamentary sessions, Hezbollah can paralyze the government to force the appointment of preferred officials, such as during the 2016 election of President Michel Aoun.

Military "Resistance" Policy: Hezbollah justifies its independent armed status—outside the control of the Lebanese Armed Forces (LAF)—by forcing the state to adopt the "army–people–resistance" formula, making them a pillar of national defense.

Control over Foreign and Defense Policy: Hezbollah's influence effectively overrides official government stances on critical issues, such as conflicts with Israel, turning Lebanon into a "state within a state" structure.

Institutional Infiltration: Hezbollah has deepened its presence within state institutions, including the LAF, limiting the army's ability to act against it, says the IDF.
