The National Movement's call for a general strike, supported by the leading Sunni politicians, Mufti Hassan Khaled, Musa al-Sadr and Raymond Edde, brought down the military cabinet on 26 May; on 28 May Frangieh appointed Rashid Karami Prime Minister.

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.

Hanf has the Syrian army moving again only once Tal al-Za'tar had fallen, increasing pressure on the encircled Palestinian and leftist forces in the Upper Metn; these were expelled at the end of September.

Ratified by an Arab summit in Cairo on 25 October, the Riyadh decisions required all parties to surrender heavy weapons and the Palestinians to return to the zones granted by the 1969 Cairo Agreement, and created a 30,000-man Arab Deterrent Force under President Sarkis, its largest contingent by far, 25,000-27,000 men, being the Syrian troops already in Lebanon. Saudi Arabia had sent the invitations on 15 October; the leaders of Saudi Arabia, Kuwait, Egypt, Syria and Lebanon met the PLO chairman in Riyadh on 16, 17 or 18 October, depending on the historian. The cease-fire's start is dated 16 October (Hanf), 21 October (Traboulsi) or 15 November (de Clerck and Malsagne).

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.

Hanf writes that the Lebanese Front was left with an enclave of roughly a tenth of Lebanon once Syrian troops had moved into the northern Christian mountains, Koura, Batroun and the coast as far as the Madfoun bridge. Frangieh gave Kataeb members in the north until the month's end to give up their weapons and quit the party, or else leave.

Fisk adds that the Syrian shelling slackened around this time after sonic booms from a pair of Israeli jets flying low over West Beirut.

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.
