Israel and Lebanon have no border dispute and no real quarrel. The wars on this front were never about Lebanon at all. They were about who kept seizing it: first the PLO, then Hezbollah, turning a weak neighbour's south into a firing line aimed at the Galilee.
This is the front the propaganda loves, because the timeline is rarely shown. Israel has no claim on Lebanese land, made peace gestures, and withdrew twice, once in 1985 and completely in 2000, a pullback the UN itself certified to the last inch. And still the rockets came. The reason is simple: two foreign-backed militias, the PLO and then Iran's Hezbollah, built states-within-the-state in the south and used it to attack Israel, whatever Beirut wanted.
The first launchpad. Expelled from Jordan, the PLO rebuilt in south Lebanon and turned it into a base for cross-border massacre. Every Israeli move north was a response. The history they skip →
1968–69 · The Cairo Agreement
Palestinian fighters move into south Lebanon and clash with the Lebanese army. The 1969 Cairo Agreement, brokered by Nasser, hands the PLO the refugee camps and the formal right to wage "armed struggle" against Israel from Lebanese soil.
1970–71 · Fatahland
Driven out of Jordan in Black September, the PLO relocates to Lebanon en masse. The south becomes "Fatahland," a state within a state: 15,000–20,000 armed fighters with their own taxes, courts and checkpoints, beyond Beirut's control, and a key trigger of Lebanon's own civil war.
11 April 1974 · Kiryat Shmona
Gunmen from Lebanon storm an apartment block in the Israeli border town and murder 18 people, eight of them children.
15 May 1974 · Ma'alot
A squad from Lebanon seizes a school full of teenagers on a field trip and murders 22 schoolchildren, wounding dozens more.
11 March 1978 · The Coastal Road
PLO fighters land by sea from Lebanon, hijack a bus and kill 38 civilians, 13 of them children. Days later Israel launches Operation Litani, pushing the PLO back from the border to the Litani river.
1981–82 · The first Lebanon war
Despite a US-brokered ceasefire, the PLO keeps shelling the Galilee, emptying towns. After the fire and the attempted assassination of Israel's ambassador in London, Israel launches the 1982 war and drives the PLO out; Arafat and his fighters are evacuated to Tunisia.
The PLO left, and Iran filled the vacuum. Out of the 1982 chaos it built its single most powerful proxy, and the launchpad reopened under new management.
1982 onward · Hezbollah is born
Iran's Revolutionary Guard founds and arms Hezbollah, a Shia militia sworn to Israel's destruction. In 1983 it bombs the US Marine and French barracks in Beirut, killing 300, and pioneers the suicide bombing the region would come to know. Iran's ring of fire →
1985 & 2000 · Israel withdraws, twice
Israel pulls back to a narrow security zone in 1985, then in May 2000 withdraws from Lebanon entirely. The UN certifies the pullback to the internationally drawn Blue Line: Israel holds not one inch of Lebanon. The pretext of "occupation" is gone. The attacks are not.
12 July 2006 · The Second Lebanon War
With no Israeli soldier on Lebanese soil, Hezbollah crosses the border, kills eight Israeli soldiers and kidnaps two, and starts a 34-day war, raining nearly 4,000 rockets on northern Israel. UN Resolution 1701 ends it and orders Hezbollah to disarm south of the Litani. It never does.
2006–2023 · The build-up
Shielded by the ceasefire, Hezbollah amasses an arsenal of over 150,000 rockets and missiles, embedded inside south Lebanon's villages, more firepower than most national armies, all of it pointed at Israel.
8 October 2023 · The second front
The day after Hamas's October 7 massacre, Hezbollah opens fire across the border in support, emptying Israel's north and displacing tens of thousands on both sides for a year.
2024 · The reckoning
Israel strikes back hard: the exploding-pager operation, the killing of Hezbollah's leader Hassan Nasrallah, and a ground campaign that guts the group's command. A ceasefire in late November 2024 again calls for Hezbollah to pull back beyond the Litani.
The cruelest part is that Lebanon itself is a victim here. A country that was once the "Switzerland of the Middle East" has been hollowed out by foreign militias stronger than its own state, first the PLO, then an Iranian proxy that drags it into wars it never chose. Lebanese civilians, Christian, Sunni, Shia and Druze alike, pay the price for fighters who launch from their towns and hide among their homes. Israel's quarrel was never with them. It was with the gun set up in their front yard.
