Lebanon: a ceasefire without peace

International Institute for Strategic Studies

A US-brokered framework agreement signed on 26 June 2026 has failed to halt Israeli military operations inside southern Lebanon or enforce Hizbullah’s disarmament. Israeli forces have established a 620-square-kilometre security zone extending up to 13 kilometres across the border, leaving over 270,000 Lebanese citizens displaced. Tactical momentum has stalled completely.

Under the Trilateral Framework, the Lebanese Armed Forces are tasked with disarming non-state groups and occupying contested border zones, but systemic underfunding and political constraints leave them incapable of executing the mandate. Meanwhile, the upcoming expiration of the United Nations Interim Force in Lebanon mandate on 31 December 2026 threatens to leave a total security vacuum along the border. With Washington conditioning military assistance on strict performance milestones and Gulf states withholding financial support, Beirut lacks the leverage to compel an Israeli withdrawal or dismantle Hizbullah’s remaining infrastructure, perpetuating a fragile, asymmetric status quo across the region.

Comment

The Trilateral Framework places an unviable operational burden on the Lebanese Armed Forces by requiring local command structures to execute disarmament mandates without political consensus or enforcement capacity. Relying on pilot deployment zones creates fragmented sectors of control where LAF units risk direct tactical friction with both the Israel Defense Forces and covert Hizbullah elements. This operational ambiguity undermines LAF cohesion, forcing brigade commanders along the Litani River to prioritise internal force survival over state sovereignty.

As the United Nations Interim Force in Lebanon prepares for total mandate termination by late 2026, the structural absence of an effective inter-agency verification body leaves border monitoring entirely unanchored. The non-executory mandate of the EU Support Mission in Lebanon ensures that tactical coordination between Beirut and northern IDF units will remain unmediated, increasing the likelihood of unverified skirmishes along the yellow line.

Strategic Question for Discussion

If the United Nations Interim Force in Lebanon completes its planned drawdown without a binding verification mechanism, can the Lebanese Armed Forces maintain internal cohesion while attempting to manage border frictions with the Israel Defense Forces?

The available evidence points toward severe institutional fragmentation within the Lebanese Armed Forces if tasked with solo border management. Without external interposition from an empowered third-party entity, brigade commanders are likely to avoid direct confrontation with remaining Hizbullah networks to prevent internal sectarian fractures. Consequently, the operational environment along the yellow line will remain vulnerable to unmediated tactical friction and unilateral IDF cross-border actions.
