Benjamin Netanyahu addresses the General Assembly on Thursday and has said he will "tell the truth" about Israel's conduct. Here is the argument he will make, stated as its defenders state it — and then the findings it has to answer.
What this piece is. This is not an endorsement and not a rebuttal. It sets out Israel's case on Lebanon as strongly and as fairly as it can be put, because most readers have only encountered it in caricature — and an argument you cannot state accurately is one you cannot assess. The final two sections give the countervailing findings with the same seriousness. Where a claim is one side's assertion rather than an established fact, it is marked.
What is actually being argued about
The live question this September is Lebanon, not Gaza. The Gaza ceasefire has held, in some form, for roughly six months. Israeli forces are in southern Lebanon.
The war resumed on 2 March 2026, when Hezbollah fired projectiles into northern Israel. That came two days after Israel and the United States attacked Iran on 28 February — an operation that included the killing of Iran's supreme leader, Ali Khamenei. Hezbollah said its aim was to force Israel to halt its aggression and leave seized Lebanese territory.
Israel's campaign has since produced an occupation of southern Lebanon, a declared "yellow line" forward defence zone covering 55 towns and villages, and more than 4,000 deaths.
Everything in the argument below turns on a document signed fifteen months before any of that.
The case, at full strength
1. The ceasefire had terms, and they were specific
The November 2024 agreement was not a vague cessation. It required Lebanon to prevent Hezbollah and all other armed groups from conducting operations against Israel, to dismantle unauthorised weapons production facilities, and to confiscate illegal arms, beginning in the south.
Most importantly, it established that in the area between the Blue Line and the Litani River, only Lebanon's official military and security forces, infrastructure and weaponry would be permitted. No other armed group. No other weapons.
Israel, for its part, agreed to cease offensive operations and withdraw south of the Blue Line within sixty days. The agreement expressly preserved each party's "inherent right of self-defence, consistent with international law."
The argument starts here: this was not an Israeli demand. It was a negotiated text, underwritten by a US-chaired monitoring mechanism, restating Security Council Resolution 1701. The zone south of the Litani was supposed to be free of Hezbollah. That is the baseline.
2. The zone was not cleared, and this is documented rather than asserted
On 8 January 2026 the Lebanese Armed Forces announced they had "achieved the objectives of the first phase" of disarmament between the border and the Litani. The announcement gave no figures for weapons confiscated or destroyed.
Israel's response was that this was "encouraging" but "far from sufficient," and from the Foreign Ministry: "Hezbollah is rearming faster than it is being disarmed." Israel published video of what it said were Hezbollah sites re-established in the town of Beit Lif, and the IDF said it had killed more than 390 Hezbollah operatives and conducted over 1,200 operations in southern Lebanon since the truce began.
What makes this plank of the case unusually strong is that it does not rest only on Israeli claims. Independent reporting through 2026 documents the same pattern. In March, three new underground shafts were found around a site previously cleared. In April, a tunnel over 140 metres long with living quarters and operational shafts. By September 2026, after the LAF declared operational control in three pilot zones, the reported haul was around 1,818 confiscated items — roughly 86 percent of it light ammunition, with no breakdown of Hezbollah depots or command centres dismantled.
And Lebanese officials have been candid about why. In August an LAF officer said troops "lacked a mandate independently to confront Hezbollah." In September the army's deputy commander, Raja Amer, told CNN the army would move "slowly" and "in a reasonable way" to avoid civil war.
Hezbollah's own leader, Naim Qassem, put it without ambiguity in June: "any project to disarm us will not pass."
3. Therefore the guarantee failed, and Israel says it cannot outsource its border
This is the heart of it. Israel's position is that it accepted a mechanism — Lebanese state control of the south, monitored internationally — and the mechanism did not deliver. The state that undertook the obligation has said plainly that it cannot enforce it. The armed group has said plainly it will not comply.
Defence Minister Israel Katz has framed the objective accordingly: operations continue until Hezbollah "no longer poses a threat to northern Israeli communities."
The argument is that a country cannot be asked to accept a rearming force on its border indefinitely on the strength of a guarantee that everyone involved concedes is unenforceable, and that the inherent right of self-defence preserved in the agreement is precisely the provision that covers this situation.
4. The distinction argument
On conduct, the case runs that Hezbollah's military infrastructure is embedded in civilian areas by design — the school in which weapons were found, the tunnel beneath a village, the position inside a town — and that under the law of armed conflict a civilian object used for military purposes may lose its protection. On this account, the resulting civilian toll is a consequence of where the weapons were put, not of indifference to who was near them.
5. The alternative on the table was rejected
In June, US Secretary of State Marco Rubio proposed a framework requiring Hezbollah to end hostilities and withdraw from southern Lebanon. Hezbollah rejected it, demanding a full ceasefire combined with full Israeli withdrawal.
Israel's point is that a diplomatic exit existed, was backed by Washington, and was refused by the party that resumed the fighting.
That is the case. Taken on its own terms it is coherent, it is grounded in a text both parties signed, and several of its factual planks hold up against non-Israeli sources. A reader who has only heard it dismissed should understand that it is not nothing.
What the case has to answer
On 22 July 2026, six UN special rapporteurs — Reem Alsalem, Morris Tidball-Binz, Koldo Casla, Paula Gaviria Betancur, George Katrougalos and Ben Saul — issued a joint statement alleging "systematic and widespread violations of international humanitarian and international human rights law."
Their specific allegations were forced displacement and prevention of return; destruction of health facilities and the targeting of medical staff; the use of white phosphorus munitions; indiscriminate attacks on residential areas.
Their figures, since 2 March 2026: more than 4,300 killed, including 392 women and 253 children; more than 12,000 injured; 620,000 displaced women and girls, among them 16,000 pregnant women. Total displacement has exceeded one million people — over a fifth of Lebanon's population. In April, UN experts separately condemned what they called unprecedented bombing following a ceasefire announcement; strikes on 8 April alone reportedly killed more than 350 people.
Four objections follow, and the case above does not dispose of any of them.
A breach does not license an unlimited response. That Hezbollah violated the agreement establishes a right to respond. It does not by itself establish that any particular strike was proportionate or that any particular target was lawful. Those are assessed one by one, and the ceasefire text does not pre-authorise them.
Some of the alleged conduct cannot be explained by embedding. White phosphorus use, prevention of return, and the targeting of medical personnel are not answered by the observation that weapons were stored in civilian areas. If substantiated, they are separate violations on their own terms.
Occupation is not self-defence. Holding a zone of 55 towns and villages, and demolishing within it, goes beyond degrading a military capability. And Finance Minister Bezalel Smotrich has proposed annexing territory up to the Litani — a proposal that is very difficult to fit inside a purely defensive frame, and which opponents cite as evidence that the objective has moved.
The trigger is contested. Israel's account begins with Hezbollah's rockets on 2 March. Lebanon's and Hezbollah's begins two days earlier, with the attack on Iran and the killing of Khamenei. Where you start the clock substantially determines who is responding to whom, and there is no neutral place to start it.
What is established and what is not
Established: the November 2024 ceasefire text and its terms. The LAF's January and September 2026 disarmament announcements and the figures in them. The statements quoted from Netanyahu's office, the Israeli Foreign Ministry, Katz, Smotrich, Qassem, Raja Amer and the LAF officer. The UN experts' statement of 22 July 2026 and the allegations in it. The Rubio framework and its rejection.
Contested: casualty totals, which come from Lebanon's health ministry and UN experts and are disputed by Israel, and whose combatant/civilian breakdown is not independently verified. Israel's characterisation of specific sites as military objectives. The extent of Hezbollah's rearmament, where Israeli claims, Lebanese claims and third-party reporting do not fully align.
Not yet adjudicated: every legal allegation above. A UN investigation into violations was announced in June 2026. Special rapporteurs make findings, not rulings. Nothing here has been tested by a court, and this piece does not pretend to substitute for one.
What to watch on Thursday
Whether Netanyahu argues the ceasefire text or the threat. The text-based argument is the stronger one and travels further with sceptical audiences. A speech built on the threat alone concedes the legal ground.
Whether he addresses the rapporteurs' specific allegations or the general charge. Answering "Israel is accused of war crimes" is easy. Answering "white phosphorus, in these villages, on these dates" is not, and the difference will be audible.
Whether annexation is mentioned. Smotrich's proposal is the single element hardest to reconcile with the defensive case. If it is disavowed from the podium, the case is more coherent. If it is not, the omission will be read.
Sourcing note: Ceasefire terms are from the published full text of the November 2024 agreement. The LAF's 8 January 2026 announcement and Israel's response, including the Foreign Ministry quotation and the IDF's operational figures, are from Times of Israel reporting. Rearmament specifics for March, April and September 2026, the LAF officer's remark, Raja Amer's CNN interview and Naim Qassem's statement are from FDD's Long War Journal, a think-tank source critical of Hezbollah — noted so readers can weigh it. The 22 July 2026 joint statement, the named rapporteurs and the casualty and displacement figures are from OHCHR. Conflict chronology, the yellow line, Katz's and Smotrich's statements, the Rubio framework and total casualty and displacement estimates are drawn from compiled reporting on the 2026 Lebanon war. Netanyahu's address is scheduled for Thursday 25 September 2026 during the 81st General Assembly's general debate; his "tell the truth" remark was made in advance of it.
