officers who staged a coup in 1966 and for the first time placed Damascus in the hands of the Alawites." The Armed Forces were involved in the 1967 Six-Day War (against Israel). Since 1967 most of the Golan Heights territory of southwestern Syria has been under Israeli occupation. They then fought in the late 1960s War of Attrition (against Israel) and the 1970 Black September invasion of Jordan. During the Yom Kippur War of 1973 the Syrian Army launched an attack to liberate the occupied Golan Heights that was only narrowly repulsed with the help of the US. Since 1973 the cease-fire line has been respected by both sides, with very few incidents until the Syrian civil war. Syria was invited into Lebanon by that country's president in 1976, to intervene on the side of the Lebanese government against PLO guerilla and Lebanese Christian forces. The Arab Deterrent Force originally consisted of a Syrian core, up to 25,000 troops, with participation by some other Arab League states totaling only around 5,000 troops. In late 1978, after the Arab League had extended the mandate of the Arab Deterrent Force, the Sudanese, the Saudis and the United Arab Emirates announced intentions to withdraw troops from Lebanon, extending their stay into the early months of 1979 at the Lebanese governments request. The Libyan troops were essentially abandoned and had to find their own way home (if at all), and the ADF thereby became a purely Syrian force (which did include the Palestinian Liberation Army (PLA)). A year after Israel invaded and occupied Southern Lebanon during the 1982 Lebanon War, the Lebanese government failed to extend the ADF's mandate, thereby effectively ending its existence, although not the Syrian or Israeli military presence in Lebanon. Eventually the Syrian presence became known as the Syrian occupation of Lebanon. Occupation of Lebanon Syrian forces, still technically known as the Arab Deterrent Force, lingered in Lebanon throughout the Lebanese civil war (1975–90). Eventually the Syrians brought most of the nation under their control as part of a power struggle with Israel, which had occupied areas of southern Lebanon in 1978. In 1985, Israel began to withdraw from Lebanon, as a result of domestic opposition in Israel and international pressure. In the aftermath of this withdrawal, the War of the Camps broke out, with Syria fighting their former Palestinian allies. Following the end of the Lebanese civil war in
