In the vocabulary of modern warfare, the word “buffer” carries a reassuring neutrality, as though the spaces being carved out between nations are merely empty margins of geography rather than places where people grow olive trees, raise children and have buried their dead for generations. Israel’s expanding military campaign in southern Lebanon depends heavily on this word, and on the bureaucratic language of security architecture that allows the elimination of hundreds of villages to be discussed in the same register as zoning regulations. What is actually being described, however, is something far older and far more brutal: the deliberate depopulation of sovereign territory under cover of a regional war that has already consumed every diplomatic norm within reach.

Israeli Prime Minister Benjamin Netanyahu announced the expansion of the military buffer zone inside Lebanon to “finally thwart the threat of invasion and to push the anti-missile threat away from our border,” words that were received with approval by residents of northern Israel who have lived under the threat of Hezbollah rocket fire for years. Their fear is real. Their desire for safety is entirely legitimate. And yet the mechanism being deployed to address that fear is one whose contours should, by now, be familiar enough to alarm anyone paying attention to what Israel has declared it intends to do with the land it is taking.

Defence Minister Israel Katz has laid out the governing principle with unusual bluntness: “where there are terror and missiles, there are no homes and no residents.” He described the planned destruction of villages in the south as proceeding “in accordance with the Rafah and Beit Hanoun model in Gaza,” invoking two neighbourhoods whose near-total destruction the Israeli military has already accomplished. This is not ambiguity. This is a government official publicly announcing that the template established in Gaza, which Human Rights Watch and multiple United Nations bodies have characterised as potential war crimes, will now be applied to Lebanese territory. The reference to Gaza was not incidental. It was deliberate, and it is important to treat it as such.

The geography of what is being proposed requires some clarity to appreciate its full scale. The government is targeting at least eighteen military positions across the area, with plans to control territory all the way up to the Litani River, roughly fifteen to twenty miles north of the Israeli border.  Then Israel ordered people out of an area ten miles north of that, north of another river called the Zahrani, extending the zone of anticipated depopulation well beyond what the initial announcements suggested. The buffer is, in practice, not a fixed line but a moving one, expanding with each announcement and driving displacement in waves. A school principal in the area described people fleeing north in waves with every new Israeli threat and every new strike, saying her school had filled up in the first wave and was now forced to turn people away. 

The human cost of this expansion has already reached a scale that demands serious attention from anyone who has not been paying it. More than eighty towns and villages have been emptied, more than fifteen percent of Lebanon’s population has been displaced, and more than 1,200 people have been killed by Israeli strikes, with thousands more wounded. That last figure encompasses Lebanese army soldiers, civilians caught in the advancing front lines, medical workers, and, most strikingly of late, United Nations peacekeepers serving with UNIFIL, the force established in 1978 specifically to monitor and contain exactly this kind of escalation between Israel and armed groups in southern Lebanon.

Three Indonesian peacekeepers were killed in two separate incidents in less than twenty-four hours, deaths that prompted France to request an emergency session of the UN Security Council and drew condemnation from the European Union, Indonesia, and the UN Secretary-General António Guterres. A UN security source confirmed to AFP that Israeli fire had killed one of the peacekeepers on Sunday, with debris from a tank round recovered at the site, a finding that contradicts the Israeli military’s claims of Hezbollah responsibility for at least some of the incidents. Israel and Hezbollah have traded accusations at the Security Council, with each blaming the other for the deaths, while the UN’s undersecretary-general for peace operations noted that the IDF had issued displacement orders for UNIFIL’s area of operations and had fired warning shots, and later a main armament round, at a UNIFIL patrol at a newly established checkpoint on March 28. 

The killing of UN peacekeepers is not, in the context of this conflict, a new development. During Israel’s previous war in Lebanon in 2024, UNIFIL personnel were struck multiple times. Since 1978, three hundred UNIFIL peacekeepers have been killed in the course of their mission. What distinguishes the current moment is the explicit Israeli ambition to reshape the territory in which UNIFIL operates, the declaration that an expanded buffer zone will remain indefinitely, and the public adoption of a doctrine that treats the civilian presence in an area as incompatible with Israeli security objectives. Speaking during the emergency Security Council session, the UN humanitarian chief Tom Fletcher asked the council directly: “Given the trajectory that some Israeli ministers have described and given what we have seen in plain sight in Gaza, how will you protect civilians?” Al Jazeera The question received no satisfactory answer, because there is none available within the current political architecture.

Israel’s stated justification for the invasion rests on the claim that Hezbollah launched its attacks on Israel in response to the killing of Iranian Supreme Leader Ali Khamenei, initiating a campaign of rocket fire into northern Israel that displaced tens of thousands of Israeli residents and killed Israeli civilians. That justification contains real elements. Hezbollah’s rocket fire from south of the Litani River did resume after the November 2024 ceasefire broke down, and the threat to Israeli border communities is not fictional. The IDF has claimed that Hezbollah was planning a ground offensive into Israel akin to Hamas’ October 7, 2023 attacks, a claim Israel has used to frame the invasion as preemptive rather than retaliatory.

What makes the current campaign categorically different from a conventional counter-terrorism operation, however, is the declared intention not to withdraw. Israel has not suggested that it will push Hezbollah back and then leave. Israel’s defence minister has said the buffer zone will remain until the security of Israel’s northern residents is guaranteed, a condition whose definition Israel alone controls and which could be maintained indefinitely. The objective, as described explicitly in Israeli planning documents and statements cited by Axios, is to transform the region south of the Litani into a demilitarized cordon under Israeli control, closely resembling the occupation regime Israel maintained through its proxy South Lebanon Army from 1978 until its formal withdrawal in 2000. 

That previous occupation, it is worth recalling, lasted twenty-two years, fuelled Hezbollah’s rise as a resistance movement, and ended not through any negotiated security framework but through a unilateral Israeli withdrawal that resolved nothing and left the conditions for future conflict intact. The lesson drawn from that history by Israel’s current leadership appears to be not that the occupation was strategically counterproductive, but that it was abandoned too soon.

The international legal framework that governs this situation is being comprehensively dismantled in real time. The declared strategy is tearing up UN Security Council Resolution 1701, which ended the 2006 war and required Israel’s withdrawal while placing limits on Hezbollah’s presence in the south. UNIFIL, which was mandated under that same resolution, is now operating in conditions where it cannot move freely, is being fired upon, and is being told by Israeli forces to evacuate the very area it was established to monitor. The force is, in the most literal sense, being pushed out of the way of an occupation it was created to prevent.

The UN humanitarian chief noted during the Security Council session that politicians in Israel are openly speaking of the intention of an extended security zone, with the destruction of villages along the Blue Line and several Litani bridges, language that has, for too long, been received by the international community as political theatre rather than operational planning. It is neither. The destruction of Rafah and Beit Hanoun proceeded exactly as announced. The destruction of southern Lebanese villages is proceeding on the same trajectory, with the same language, the same institutional impunity, and the same international paralysis.

Lebanon as a state, already among the most fragile political constructs in the Middle East after decades of civil war, Syrian occupation, economic collapse, and the Beirut port explosion of 2020, has no military capacity to resist this invasion. The UN special coordinator for Lebanon, Jeanine Hennis-Plasschaert, said that the humanitarian impact in southern Lebanon has reached devastating levels and warned that the longer this goes on, the harder it will be to come back from. More than a million people are displaced. Medical infrastructure, water stations, and power facilities have been damaged and destroyed. If the south is permanently occupied and its residents prevented from returning, the social and political consequences for Lebanon as a functioning state will be catastrophic and potentially irreversible.

The question that hangs over all of this, and that the Security Council’s emergency session on Tuesday could not answer, is whether any power or combination of powers has the will or the capacity to stop what is happening. The United States, which holds decisive influence over Israel and is simultaneously conducting its own war against Iran, has shown no inclination to constrain Israeli operations in Lebanon. The American delegate at the Security Council asked the world to reserve judgment and await the results of investigations into the deaths of UN peacekeepers, a position that, under the circumstances, functions as permission to continue. France, which has a long historical relationship with Lebanon and commands one of the largest UNIFIL contingents, is pressing for accountability through the very institution, the Security Council, whose effectiveness is neutralised by the American veto.

History will record that the invasion of southern Lebanon in 2026 was announced clearly, justified with familiar language, conducted under the cover of a larger regional war, and met with the same ineffectual international response that has accompanied every previous episode of mass displacement in this conflict. A “buffer zone” is being created. The buffer is made of rubble. The zone is made of absence. And the people who lived in the villages being dismantled have nowhere to go that is not also, eventually, at risk.
