He studied at the Damascus University where he joined the radical, pro-Syrian Popular Front for the Liberation of Palestine – General Command (PFLP-GC) under Ahmed Jibril in 1968. In 1977, major disagreements arose between the PFLP-GC, the Palestine Liberation Organization (PLO), and other Palestinian factions based in Lebanon. Zaidan, who opposed Syrian involvement in the Lebanese war, left the PFLP-GC and created the PLF with Talaat Yaacoub, which eventually split into three separate factions (and then later re-merged). Zaydan's faction of the PLF, which was the largest of the three, moved its headquarters to Tunisia.
