On June 28, 1999 Farid Abboud, the Lebanese ambassador to the US, addressed the Los Angeles World Affairs Council[24] to give an update on the peace process.[25] Finally, on May 23, 2000, the Israeli military carried out a withdrawal of Israeli troops from the south and the Bekaa valley, effectively ending 22 years of occupation. The SLA collapsed and about 6,000 SLA members and their families fled the country, although more than 2,200 had returned by December 2001. With the withdrawal of Israeli forces, many in Lebanon began calling for a review of the continued presence of Syrian troops, estimated in late 2001 at approximately 25,000.
