Formed in September 1975 through Syria's foreign minister Abdel Halim Khaddam, the National Dialogue Committee of some twenty leaders debated secularism and ending sectarian quotas; Hanf says it broke up empty-handed.

Parliament used the truce to amend Article 73 of the constitution so that Frangieh's successor could be elected early: on 9 April according to Hanf, 10 April according to Yara El Khoury. The truce had coincided with the arrival on 31 March of the US envoy Dean Brown.

Its unprecedented powers spanned planning, funding and running reconstruction. It replaced the Planning Ministry in 1977; Picard calls it the economy's 'superministry'.

Historians date the start of Operation Litani to 14 March (de Clerck and Malsagne, Traboulsi, Quéméner; de Clerck's chronology gives 15 March) and its end to 21 March. Up to 25,000 Israeli soldiers and 120 tanks took part (de Clerck and Malsagne). Estimates of the dead range from about 300 Palestinian fighters (de Clerck and Malsagne) to about 2,000 people, mostly civilians (Fisk; de Clerck and Malsagne; Picard). Estimates of the displaced range from 150,000 (Hanf's refugee table) and more than 200,000 (de Clerck and Malsagne, Picard) to 285,000 (Lebanese government figure cited by Fisk). On 15 March Israeli aircraft bombed the Palestinian camps of Beirut, Tyre and Damour.

Colonel Jean Germain Salvan was badly hurt in both legs in early May, Fisk writes, when dissident PLO gunmen fired on the Fatah jeep carrying him, killing a French soldier and his Palestinian driver; Arafat called it a crime. Hanf adds that such losses made the French unit much more careful.

De Clerck and Malsagne have Iranian clerics and activists settling in the Bekaa, and then in Tyre, from 1980, before 500 to 2,000 Revolutionary Guards entered Lebanon in June 1982.

Officially no killer was named, but al-Lawzi's murder was widely blamed on his criticism of Syrian rule (Fisk; Picard). Fisk: he was seized near a Syrian army checkpoint heading for the airport.

Historians date the battle of Zahleh from this day, when Lebanese Forces fighters beat off a Syrian attack on the town and a siege of some 90 days began. Ménargues says Syrian heavy guns killed 50 and wounded over 200 that day in Zahleh and the Christian zone north of Beirut.

The cease-fire came from separate talks with Israel and the PLO, helped by Saudi diplomats (Hanf), with the UN relaying to the PLO (Ménargues, Fisk). Border fire was to stop; Syria could keep its Bekaa missiles unused, and Israeli overflights continued. In Ménargues's account a last Israeli demand held up Israel's public acceptance for two days.
