A permanent military buffer zone would fundamentally undermine the Lebanese state's claim to territorial integrity. By physically occupying large swaths of southern territory, Israel effectively strips the central government of its ability to govern its own borders. This creates a vacuum where Lebanese security forces cannot deploy, leaving local populations under the de facto control of external military actors.
Such a reality alters the domestic balance of power. If the Lebanese Army cannot re-establish authority in these zones, non-state actors and armed groups gain further legitimacy. They can frame themselves as the only real protectors of the people, further weakening the central government's mandate. This erosion of state authority makes it harder for Lebanon to function as a unified political entity.
On the regional stage, this presence fixes a state of perpetual tension. It turns the southern border into a permanent frontline rather than a diplomatic boundary. Such a fixture invites constant friction and prevents the normalization of relations. Ultimately, it locks the region into a cycle of containment rather than coexistence, making any future political settlement much harder to reach.
