sentences:  During the war of 1975–1990, some right-wing militias were Israel's allies, and after the assassination of President Bachir Gemayel, Israel and Lebanon signed an agreement on 17 May 1983 which was a peace treaty in all but name.The Lebanese legislature ratified the treaty by a margin of 80 votes, but in a very weak and unstable domestic position president Amine Gemayel abrogated the peace treaty on 5 March 1984 under unrelenting Syrian pressure, after the U.S. Marines withdrew and after Israel had begun withdrawing from Lebanon.During the Syrian Occupation of Lebanon (1976–2005), it was highly unlikely that Lebanon would sign a peace treaty with Israel before Syria, as Syria's influence on Lebanese politics was strong; although Syria has withdrawn from Lebanon, the Iran–Syria–Hezbollah axis remains entrenched through the heavy arms presence.
