The war widens into Lebanon

What does it mean when a state's own inquiry finds against its own minister?

Option B7 · The Middle East: conflict, crisis and change, 1917–2012 › Key topic 4 · Diplomacy, peace then wider war, 1973–83 — one of 2 lessons in this key topic. Paper 2 Section B — breadth study in change: The Middle East: conflict, crisis and change, 1917–2012, key topic 4 (30 marks: 6 · 8 · 16).

Learn the war widens into Lebanon, teach it to an AI pupil, then defend it in a marked debate — this lesson carries all three.

What the specification asks for

“Widening of the conflict into Lebanon (1982-83), including the role of the PLO.” — examined through consequence. Incandio is aligned to specification 4HI1; it is not published by, endorsed by or affiliated with Pearson.

1 · Understand it

Why Lebanon

The PLO's expulsion from Jordan in 1970–71 moved its leadership and forces to Lebanon, a country whose political system distributed power between religious communities on the basis of a census taken decades earlier and whose balance was already under strain. Civil war broke out there in 1975, drawing in Syrian forces the following year.

By the early 1980s the PLO operated in effect as an armed authority in parts of Lebanon, including the south, from which attacks were mounted across the Israeli border and to which Israel replied. A ceasefire negotiated in 1981 held imperfectly.

The Israeli government, with Ariel Sharon as Defence Minister, planned an operation to remove the PLO from Lebanon and, beyond that, to install a friendly government in Beirut. The stated objective at the outset was more limited than the operation that followed, which is one of the criticisms subsequently made within Israel.

1982

Israel invaded in June 1982, advanced far beyond the initially stated line, and besieged Beirut through the summer. The siege ended with an internationally supervised evacuation: the PLO leadership and thousands of fighters left Lebanon for Tunis and other Arab states, with guarantees given for the safety of the civilian population remaining in the refugee camps.

In September the Lebanese president-elect, an ally of Israel, was assassinated. Israeli forces entered West Beirut, and Lebanese militia allied to Israel were permitted into the Sabra and Shatila refugee camps. Over about two days they killed a large number of Palestinian and Lebanese civilians; estimates range from several hundred to over three thousand and remain disputed.

The consequences inside Israel were immediate and are the reason this strand carries the weight it does. A very large demonstration was held in Tel Aviv, and the government appointed a commission of inquiry under the president of the Supreme Court.

The Kahan Commission and after

The Kahan Commission reported in 1983. It found that the killings had been carried out by the Lebanese militia, and that Israeli ministers and commanders bore indirect responsibility for having permitted the militia into the camps when the risk was foreseeable. It recommended that the Defence Minister be removed from that office; he resigned it while remaining in the government.

That finding is unusual evidence and should be used as such. A state investigated its own conduct in a war it was fighting, published the result, and named its own minister. Whether the finding went far enough is argued about; that it exists at all is what makes it citable, and a candidate who can quote a state's own inquiry against its own actions has a stronger argument than one relying on an opponent's claims.

The wider consequences ran for years. Israeli forces remained in southern Lebanon until 2000. Hezbollah formed in the years after the invasion, in the conditions the war created, and became a more capable long-term opponent than the PLO had been in Lebanon — so an operation intended to remove one adversary contributed to the emergence of another. The PLO, meanwhile, was in Tunis, far from the territories, which is part of why the initiative passed to the population of the West Bank and Gaza in the Intifada of 1987.

2 · Learn it — the notes

The dates that earn marks

1975
Civil war begins in Lebanon, with Syrian intervention the following year. Why this date: The Israeli invasion entered a war already running, which is why the situation could not be controlled by removing one party.
June 1982
Israel invades, advances beyond the stated line and besieges Beirut; the PLO leadership leaves for Tunis. Why this date: It removes the PLO from Israel's border and places its leadership a thousand miles from the territories it claimed to represent.
September 1982
The Sabra and Shatila massacres. Why this date: It produced the largest protest in Israeli history to that point and a state commission of inquiry.
1983
The Kahan Commission reports and finds indirect responsibility. Why this date: A state naming its own minister in its own inquiry is unusually strong evidence for a candidate to deploy.

The figures, and how far to trust them

  • Disputed, from several hundred to over three thousand — Those killed at Sabra and Shatila in September 1982. (No agreed count exists; the range should be given rather than a single figure.)
  • 1982 to 2000 — The period Israeli forces remained in southern Lebanon after the invasion.
  • Thousands of fighters — PLO personnel evacuated from Beirut to Tunis and other Arab states under international supervision. (Figures vary between accounts of the evacuation.)

The people to place

  • Ariel Sharon — Israeli Defence Minister; found to bear indirect responsibility by the Kahan Commission and removed from that office.
  • Yasser Arafat — Left Beirut for Tunis with the PLO leadership under the evacuation agreement.

How historians disagree

Attributed interpretations, never voiced — the AO4 seam.

  • The 'counter-productive operation' reading: The invasion removed the PLO from Lebanon and produced an eighteen-year occupation, a new and more capable opponent in Hezbollah, and a massacre for which Israel's own commission found its ministers indirectly responsible. Contested by The reading that the operation achieved its principal aim — the PLO's removal from Israel's northern border, which ended attacks from that quarter — and that Hezbollah's emergence owed as much to the Lebanese civil war and to Iran as to the invasion..

What students say — and what is actually the case

Not this: Israeli forces carried out the Sabra and Shatila massacres.

This: The Kahan Commission found that Lebanese militia carried them out and that Israeli ministers and commanders bore indirect responsibility for permitting the militia into the camps. The distinction is the commission's own and should be stated precisely.

Not this: The invasion of 1982 ended Israel's problems on its northern border.

This: Israeli forces remained in southern Lebanon until 2000, and Hezbollah formed in the conditions the war created and proved a more capable opponent than the PLO had been there.

Two things students merge

Blurred: Direct and indirect responsibility.

The distinction: The Kahan Commission's finding was of indirect responsibility for permitting a foreseeable risk. Overstating it as direct responsibility loses the precision that makes the source powerful.

Blurred: The PLO in Lebanon and the PLO in Tunis.

The distinction: After 1982 the leadership was a thousand miles from the West Bank and Gaza, which is a large part of why the initiative in 1987 came from the population of the territories rather than from the organisation.

What a Grade 9 answer holds here

A Grade 9 answer uses the Kahan Commission rather than describing it. A government that appoints a judge to investigate its own war, publishes a finding of indirect responsibility against its own defence minister and removes him from that office has produced evidence about itself that no opponent could have obtained — and quoting a state against itself is the strongest move available on a contested topic.

3 · How it is examined

This strand is genuinely set through: Paper 2 Section B (a) (6 marks — “Explain TWO ways in which … was different from ….”); Paper 2 Section B (b) (8 marks — “Explain TWO causes of ….”); Paper 2 Section B (c)(i) or (c)(ii) (16 marks — “How significant was … in …, in the years …? / How far were … responsible for …, in the years …? You may use the following in your answer: • [prompt] • [prompt]. You must also use information of your own.”).

What earns marks: The Kahan finding stated exactly — indirect responsibility, by Israel's own commission, followed by a resignation. Precision here is worth more than emphasis.

The cap that bites here: The 8-mark question is held at 4 marks if only one cause is explained.

4 · Prove it — the questions

Answered inside Incandio, where a marker checks what a correct answer must contain and tells you which half was missing. The marking stays in the app; the questions are here.

  1. Explain TWO ways in which the war in Lebanon was different from earlier Arab–Israeli wars. [6 marks · Paper 2 Section B (a)]
  2. Explain TWO causes of the Israeli invasion of Lebanon in 1982. [8 marks · Paper 2 Section B (b)]
  3. Explain TWO causes of the criticism of the Lebanon war inside Israel. [8 marks · Paper 2 Section B (b)]
  4. How significant was the Lebanon war of 1982 in the Arab–Israeli conflict, in the years 1917–2012? [16 marks · Paper 2 Section B (c)(i) or (c)(ii)]
  5. How far did the invasion of Lebanon achieve its aims? [16 marks · Paper 2 Section B (c)(i) or (c)(ii)]

Think you understand it?

Reading is the start. On Incandio a topic counts as mastered only once you have taught it and defended it — the two things a revision guide cannot ask of you.

Incandio this topic → Prove it. Teach it. Defend it. What does “Incandio it” mean?

  1. Prove it — five questions on the war widens into Lebanon, marked on the spot, that tell you what was missing rather than just what was wrong.
  2. Teach it — Explain the war widens into Lebanon — what happened, why, and what it made possible — to Ember, an AI pupil who asks the awkward question. Understanding is credited; wording is not required.
  3. Defend it — Argue the war widens into Lebanon against the historical mind with the strongest claim on it — three rounds, marked against descriptors you can read before you begin.
  4. Then the exam — 15 authored exam-style questions on this option, marked on Incandio with the mistake you actually made named.
