Israeli forces have seized Beaufort Castle, the 12th-century Crusader fortress perched above the Litani River in southern Lebanon, in what correspondents are describing as the deepest Israeli military incursion into Lebanese territory in more than 26 years. The castle — known in Arabic as Qalaat al-Shaqif — commands panoramic views over both northern Israel and the approaches to the Beqaa Valley. It was the last position Israel evacuated when it ended its 18-year occupation in May 2000. Lebanese Prime Minister Nawaf Salam has described the Israeli advance as a “scorched earth policy,” and the move appears to have shattered the US-brokered ceasefire framework that has nominally governed southern Lebanon since November 2024. UN forces in the area have reported being unable to operate freely in affected zones.
The received wisdom
The mainstream framing is straightforward and, in its own terms, defensible: Israel is responding to ongoing Hezbollah provocations along the Blue Line, its military retains the right of hot pursuit under the laws of armed conflict, and a durable security buffer is a legitimate objective given Hezbollah’s history of rebuilding its military infrastructure whenever external pressure eases. The Guardian notes that Hezbollah’s military wing has not been fully disarmed under the 2024 ceasefire arrangement, and that Lebanese Armed Forces have struggled to deploy credibly south of the Litani. From this vantage point, what looks like aggression is actually enforcing a ceasefire that Lebanon’s government proved incapable of upholding. Progressive critics of Israel, the argument runs, need to explain what alternative security guarantee they would offer instead of Israeli force.
That is a real argument. It deserves to be answered, not dismissed.
A different read
The problem is that Israel has run this playbook before — and it ended badly even by Israel’s own assessment.
The first Lebanon occupation, from 1982 to 2000, began with identically plausible security logic: the PLO was shelling northern Israel from Lebanese territory; a buffer zone was needed; the Lebanese state was too weak to enforce order. What followed was 18 years of grinding insurgency, the creation of Hezbollah itself as a direct organisational response to the occupation, and a withdrawal that Israel’s own military analysts described as a strategic defeat. NPR’s reporting specifically notes that Beaufort Castle was a symbol of that occupation, held by Israeli forces throughout the 1982–2000 period. Re-hoisting the flag over it is not merely a tactical manoeuvre; it is a statement about the durability of Israeli presence.
The “Greater Israel” ideological thread that NPR identifies — fringe legislators and activists now arguing for permanent territorial expansion into Lebanon, Syria, and beyond — matters here. It is not that such voices control Israeli policy. They demonstrably do not yet. But Benjamin Netanyahu’s current coalition depends on far-right partners for whom the occupation’s end was always a humiliation to be reversed, and the logic of military momentum is notoriously difficult to reverse once established. The question is not whether Beaufort Castle falls to Israeli forces — it already has — but what happens in month 18 of occupation when the next generation of Lebanese militants has learned from Hezbollah’s 1980s textbook.
There is also the diplomatic wreckage to consider. The US-brokered November 2024 ceasefire was the Biden administration’s most significant Middle East legacy and represented an implicit American guarantee to Lebanon’s territorial integrity. By allowing — or failing to prevent — Israeli forces from advancing beyond the Litani, Washington has destroyed Lebanese state credibility in the south. Prime Minister Salam was a reformist figure with genuine goodwill in western capitals; his description of Israeli conduct as “scorched earth” reflects not rhetorical excess but the political reality that he cannot survive domestically if his government is seen as complicit in a new occupation. The moderate Lebanese political space that American diplomacy spent years cultivating has been substantially narrowed.
The Guardian’s analysis draws a pointed comparison: this is the deepest Israeli incursion since the 2000 withdrawal, a threshold crossed with no announced political objective beyond security. When military operations lack defined political endpoints, they tend to find their own — usually more expansive — ones. The historical parallel that should concern Western policymakers is not Gaza 2023–24 but South Lebanon 1982–2000: a war that began as a security operation, produced a new and more dangerous enemy, and ended only when Israel itself concluded the costs were unsustainable. The question is whether this iteration proceeds faster or slower to the same destination.
What to watch
- Whether the US formally protests the Litani crossing or provides diplomatic cover — the answer will reveal whether Washington views the ceasefire framework as still operative.
- Netanyahu’s domestic political calculus: if the Knesset’s far-right bloc formally demands permanence in southern Lebanon, the pressure on the coalition to deliver it will be severe.
- Lebanese state fragility: if Salam’s government falls or loses parliamentary confidence, the last institutional buffer between Israeli forces and Hezbollah’s reconstituting remnants disappears.
- Iranian reaction — Tehran has been negotiating with Washington over a nuclear framework; an Israeli advance of this scale tests whether the Iran deal trade-offs include Lebanon as a concession or a flashpoint.
