Hanf writes that once Jisr al-Pasha fell on 1 July the Palestinians struck in the north, taking coastal Chekka from Tripoli by way of the Koura, with massacres, looting and arson. A Lebanese Front counter-attack with army tanks reached Tripoli's outskirts.

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).

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.

Probably the text Picard lists as President Sarkis's 'Fourteen Points' (March 1980), one of the drafts that fed into the Taif Accord. Traboulsi notes that in that same month an American spokesman called on Lebanon to sign up to the Camp David accords.

According to Ménargues, Syria's foreign minister Abdel Halim Khaddam brought a five-page paper to Baabda on 5 May. In effect a Lebanese–Syrian accord on institutions, politics, the economy and culture, down to school curricula, it was rejected by the Kataeb leader Pierre Gemayel.

The raid targeted PLO offices in the Fakhani district of West Beirut. Tolls differ: Ménargues gives 191 dead and over 730 wounded; Fisk and Picard about 300 dead; Hanf hundreds killed and over a thousand hurt, chiefly civilians.
