This analysis proceeds from the view that durable stability requires enforceable sovereignty — the ability of a state to exercise exclusive control over the use of force within its territory. It evaluates Hezbollah through that lens while engaging competing interpretations of its origins and role within Lebanese society.
Introduction: A Pattern Without Resolution
Over the past two decades, multiple agreements have attempted to stabilise southern Lebanon. Each has followed a similar trajectory: a period of conflict, an international framework for disarmament or control, and a return — sooner or later — to renewed confrontation.
This recurring pattern suggests something more than failed implementation. It points to a deeper problem: the requirements of these agreements have consistently exceeded the capacities of the system expected to enforce them.
Origins, Legitimacy, and Constraint
Hezbollah emerged in the early 1980s at the intersection of two forces: the Israeli military presence in southern Lebanon (1978–2000), and the ideological model of the Iranian Revolution under Ayatollah Ruhollah Khomeini.¹
For many Lebanese Shia, Hezbollah was initially a resistance movement — filling a security vacuum left by the state. That perception remains central to its domestic legitimacy.
At the same time, Hezbollah’s 1985 manifesto articulated goals that extended beyond resistance: the destruction of Israel, the establishment of an Islamic political order, and alignment with Iran.² Its 2009 political document softened some of this language, particularly regarding the imposition of an Islamic state in Lebanon, but did not alter its strategic orientation.³
The result is a hybrid identity — locally rooted, but externally aligned — and it is this combination that produces the central constraint.
Hezbollah functions as a veto actor: an organisation capable of preventing the Lebanese state from acting against it while remaining embedded within that state’s political system. Its coercive capacity is reinforced by social legitimacy within parts of the population, meaning that disarmament would not be experienced as a neutral administrative step, but as a politically destabilising shift in the balance of power and security.
2006 and Resolution 1701: Design Without Capacity
The 2006 war led to United Nations Security Council Resolution 1701, which required Israeli withdrawal, deployment of the Lebanese Armed Forces and United Nations Interim Force in Lebanon (UNIFIL), and the disarmament of Hezbollah south of the Litani River.⁴
The framework assumed enforcement by actors who were, in practice, constrained. UNIFIL operated under a limited mandate and the political caution of troop-contributing countries unwilling to confront Hezbollah directly, while the Lebanese Armed Forces lacked the capacity to act without risking internal fragmentation.⁵
The issue was not simply that the agreement was not enforced. It was that it required actions the system could not sustain. This misalignment is visible in the role assigned to UNIFIL; a force mandated to support the disarmament of a heavily armed non-state actor, but neither authorised nor structured to compel it. Operating under restrictive rules of engagement and dependent on the consent of the host state — itself unable to confront Hezbollah — UNIFIL functioned less as an enforcement mechanism than as a stabilising presence within the limits imposed upon it.
Syria and the Expansion of Constraint
Hezbollah’s intervention in Syria in support of Bashar al-Assad marked a further shift.
It demonstrated that Hezbollah had evolved into an expeditionary force integrated into Iran’s regional strategy, with expanded logistical networks and operational depth.⁶ This transformation strengthened its military position while further reducing the feasibility of Lebanese state enforcement.
Hezbollah was no longer only embedded domestically. It was structurally connected to a wider military system.
Deterrence Is Not Enforcement
The period following 2006 is often described as one of relative stability. A more precise description is that deterrence substituted for enforcement.
Hezbollah expanded its arsenal significantly — widely estimated, prior to the 2023–2024 conflict, at over 150,000 rockets and missiles, with subsequent Israeli operations reducing portions of that stockpile.⁷ Some analyses, including Israeli military assessments and UN reporting, indicate that elements of this infrastructure have been embedded within civilian areas, though the extent and intent of this practice remain contested.⁸
Deterrence shapes behaviour without eliminating capability; enforcement alters the underlying condition.⁹
The events of October 2023 illustrate this dynamic. Hezbollah’s decision to open a northern front — likely coordinated at least at a strategic level within Iran’s network, though the degree of operational synchronisation remains debated — demonstrated how quickly deterrence can erode once conflict resumes.
The underlying capability had never been addressed.
From Enforcement Gap to Systemic Constraint
The recurring pattern is clear: agreements mandate disarmament; enforcement is assigned to constrained actors; rearmament continues; conflict returns.
This is often described as an enforcement gap.
A more accurate formulation is that enforcement is structurally constrained to the point of impracticality under current conditions.
Why the Constraint Persists
Meaningful enforcement would require changes across three domains: Lebanese political realignment, a revised international mandate, and reduced Iranian reliance on Hezbollah as a forward deterrent.
These conditions are not merely absent. They are interdependent in ways that make sequential progress unlikely: Lebanese political realignment is blocked by Hezbollah’s coercive capacity and external backing; that backing persists because Hezbollah functions as a core component of Iran’s regional deterrence strategy; and altering that strategy would likely require broader regional accommodation involving the United States and its allies — a process constrained by competing strategic interests and domestic political limits across multiple actors.¹⁰
This interdependence is what makes the problem systemic rather than procedural.
It is not that solutions are unknown. It is that the conditions required to implement them cannot be generated within the current configuration of incentives.
Conclusion: The Structure That Remains
The history of Hezbollah does not show that enforcement was neglected.
It shows that enforcement, as envisioned in international agreements, has been consistently incompatible with the system expected to deliver it.
As a result, deterrence continues to substitute for enforcement. Capability accumulates beneath periods of calm. And when conflict returns, it does so on a larger scale.
This is not a failure of understanding. It is the persistence of a structure.
