The warnings have already begun. UN peacekeeping chief Jean-Pierre Lacroix says discussions over what replaces the force must begin urgently. Lebanese officials want some form of continued UN presence. Supporters of UNIFIL warn that its departure could create a dangerous security vacuum. But after 48 years, there is a more basic question worth asking: What exactly did UNIFIL prevent? The force was established in March 1978 after Israel invaded southern Lebanon. Its original mission was to confirm Israel’s withdrawal, restore international peace and security, and help the Lebanese government restore its authority in the south. Forty-eight years later, Israeli troops are again inside Lebanese territory, Hezbollah remains armed, the Lebanese state still does not exercise an uncontested monopoly over weapons, and southern Lebanon has repeatedly become a battlefield. That makes it difficult to describe UNIFIL as a strategic success. Israel invaded Lebanon again in 1982 despite the force already being there. Israeli troops remained in southern Lebanon until 2000. Six years later, Hezbollah and Israel fought another major war. The Security Council then dramatically expanded UNIFIL's role through Resolution 1701, which called for an area between the Blue Line and Litani River free of armed personnel and weapons other than those belonging to the Lebanese state and UNIFIL. The mission was tasked with assisting the Lebanese Army toward that objective. That objective was never achieved. Hezbollah rebuilt and expanded its military capabilities after 2006. Weapons, fighters and military infrastructure remained in southern Lebanon. Then, beginning on October 8, 2023, Hezbollah and Israel again exchanged fire across the border, ending what UNIFIL itself describes as roughly 17 years of relative calm. Further major conflicts followed in 2024 and 2026. UNIFIL remained in place throughout. This does not mean peacekeepers personally failed to perform their assigned duties. It means the mission was never capable of solving the problem it was supposedly helping contain. UNIFIL was not given a mandate to wage war against Hezbollah and forcibly confiscate its arsenal. It depended heavily on cooperation from the Lebanese state, and its mandate emphasized monitoring, supporting the Lebanese Army and reporting violations rather than independently imposing Resolution 1701 by force. That distinction is important. But from Lebanon's perspective, the outcome is what ultimately matters. A peacekeeping force can submit reports documenting violations for decades. If the weapons remain, the border remains unstable and another war eventually begins, those reports have limited strategic value. The same applies to Israeli violations. UNIFIL has repeatedly documented Israeli crossings of the Blue Line, air activity and military operations inside Lebanese territory. In February, it said an Israeli drone dropped a stun grenade near one of its patrols. During the March escalation, it documented Israeli movements inside Lebanon alongside rockets and missiles being launched toward Israel from Lebanese territory. It could report those events. It could condemn them. It could communicate with both sides. It could not stop them. That is the central limitation of UNIFIL. Its presence provided observation without enforcement. And that is why predictions of a dramatic security vacuum should be treated cautiously. The forces actually determining whether southern Lebanon goes to war are not UN peacekeepers. They are Israel and Hezbollah. If Hezbollah retains an independent arsenal and decides to use it, UNIFIL cannot stop the decision. If Israel decides that military action is necessary, UNIFIL cannot prevent Israeli aircraft or troops from acting. If the Lebanese state wants sovereignty, the only institution capable of establishing it permanently is the Lebanese state itself. That reality has become even clearer in 2026. The current U.S.-backed process for Israeli withdrawal and Hezbollah disarmament is being negotiated largely outside UNIFIL. The first pilot withdrawal zone showed that implementation depends on direct arrangements between Israel, Lebanon, the United States and the Lebanese Army, not on blue helmets independently imposing a settlement. Europe appears to recognize the same reality. The EU has just established a three-year mission designed to strengthen the Lebanese Army and Internal Security Forces in border security, maritime surveillance and anti-smuggling operations. It is explicitly intended to help Lebanese institutions take on greater responsibility as UNIFIL withdraws. That is a more sustainable model. Lebanon should not require thousands of foreign soldiers indefinitely to patrol its own territory. UNIFIL was called an “interim” force when it arrived in 1978. It is still here almost half a century later. An interim mission lasting 48 years is itself evidence that the underlying political problem was never solved. Its withdrawal will therefore matter operationally. There will be fewer international patrols. A useful liaison mechanism will disappear unless replaced. Humanitarian and monitoring functions will have to be transferred elsewhere. But strategically? Very little changes unless Lebanon changes. The same questions remain whether UNIFIL has 7,500 troops, 3,000 troops or none at all. Will Hezbollah surrender its independent weapons? Will Israel withdraw from Lebanese territory? Will the Lebanese Army control the border and the area south of the Litani? Will the Lebanese government finally possess a genuine monopoly over decisions of war and peace? Those questions determine whether southern Lebanon is secure. UNIFIL never could. After nearly five decades, its departure may finally force Lebanon and the international community to stop treating peacekeeping as a substitute for sovereignty.
