interesting bit of history:
Between Fatah and the Rejectionists
In 1974, the same year as the PDFLP changed its name into the Democratic Front for the Liberation of Palestine (DFLP), it acted as a strong supporter of the 1974 Ten Point Program. This document, which was accepted by the Palestinian National Council (PNC) after lobbying by Fatah and DFLP, cautiously introduced the concept of a two-state solution in the PLO, and caused a split in the organization leading to the formation of the Rejectionist Front, where radical organizations such as the PFLP, PFLP-GC, Palestine Liberation Front and others gathered with the backing of Syria, Libya and Iraq to oppose Arafat and the mainstream PLO stance.
In 1974 the organization perpetrated a major terror attack in Israel, when attacking a local elementary school in the village of Ma'alot. Taking the school-kids for hostage, 22 children aged 14–16 years-old were killed when an army commando engaged them.
In 1978 the DFLP temporarily switched sides and joined the Rejectionist Front after clashing with Arafat on several issues, but it would continue to serve as a mediator in the factional disputes of the PLO. In the tense situation leading up to the 1983 Fatah rebellion, during the Lebanese Civil War, the DFLP offered mediation to prevent the Syrian-backed formation of a rival Fatah leadership under Said al-Muragha (Abu Musa), the Fatah al-Intifada faction. Its efforts ultimately failed, and the PLO became embroiled what was in effect a Palestinian civil war.
