Any of this sounds familiar?

------------
PLO attacks from Lebanon into Israel in 1977 and 1978 escalated tensions between the countries. On 11 March 1978, eleven Fatah militants landed on a beach in northern Israel and proceeded to hijack two buses full of passengers on Haifa - Tel-Aviv road, shooting at passing vehicles. They killed 37 and wounded 76 Israelis before being killed in the firefight with the Israeli forces. [1] Israel invaded Lebanon four days later in Operation Litani. The Israeli Army occupied most of the area south of the Litani River, resulting in the evacuation of at least 100,000 Lebanese (Smith, op. cit., 356), as well as approximately 2,000 deaths (Newsweek, 27 March 1978; Time, 3 April 1978; cited in Chomsky, Towards a New Cold War, p. 485 n115). The UN Security Council passed Resolution 425 calling for immediate Israeli withdrawal and creating the UN Interim Force in Lebanon (UNIFIL), charged with maintaining peace.

Israeli forces withdrew later in 1978, but retained control of the southern region by managing a 12-mile wide "security zone" along the border. To hold these positions, Israel installed the South Lebanon Army (SLA), a Christian-Shi'a proxy militia under the leadership of Major Saad Haddad. Israel liberally supplied the SLA with arms and resources, and posted "advisors" to strengthen and direct the militia.

Violent exchanges resumed between the PLO, Israel, and the SLA, with the PLO attacking SLA positions and firing rockets into northern Israel, Israel conducting air raids against PLO positions, and the SLA continuing its efforts to consolidate power in the border region.

In August (1981), Israeli prime minister Menachem Begin was re-elected, and in September, Begin and his defense minister Ariel Sharon began to lay plans for a second invasion of Lebanon for the purpose of driving out the PLO. Sharon's intention was to "destroy the PLO military infrastructure and, if possible, the PLO leadership itself; this would mean attacking West Beirut, where the PLO headquarters and command bunkers were located"
srael launched Operation Peace for Galilee on June 6, 1982, attacking PLO bases in Lebanon… Sharon described it as a plan to advance 40 kilometers into Lebanon, demolish PLO strongholds, and establish an expanded security zone that would put northern Israel out of range of PLO rockets.

UN resolutions:

After the invasion had begun, the UN Security Council passed a further resolution on 6 June 1982, UNSCR 509, which reaffirms UNSCR 508 and "demands that Israel withdraw all its military forces forthwith and unconditionally to the internationally recognized boundaries of Lebanon" [3]. Thus far the US had not used its veto. However, on 8 June 1982, the US vetoed a proposed resolution that "reiterates [the] demand that Israel withdraw all its military forces forthwith and unconditionally to the internationally recognized boundaries of Lebanon" [4], thereby giving implicit assent to the Israeli invasion.

On 26 June, a UN Security Council resolution was proposed that "demands the immediate withdrawal of the Israeli forces engaged round Beirut, to a distance of 10 kilometres from the periphery of that city, as a first step towards the complete withdrawal of Israeli forces from Lebanon, and the simultaneous withdrawal of the Palestinian armed forces from Beirut, which shall retire to the existing camps" [7]; the United States vetoed the resolution because it was "a transparent attempt to preserve the P.L.O. as a viable political force"

By September,… Israeli forces had pulled out from all but the southern security zone. The IDF would remain in this zone, in violation of UN Security Council resolution 425, until the 2000.

And this sounds like Harriri Lebanese Prime Minister recently assasinated by Syria)

The Taif Agreement of 1989 marked the beginning of the end of the fighting… The agreement provided a large role for Syria in Lebanese affairs. Returning to Lebanon, they ratified the agreement on November 4 and elected Rene Mouawad as President the following day. Military leader Michel Aoun in East Beirut refused to accept Mouawad, and denounced the Taif Agreement.

Mouawad was assassinated 16 days later in a car bombing…

Are we heading here, again? Not if the Israeli's get their way, and if they go all the way this time, regardless of UN resolutions. Why not ignore the UN? Everyone else does. And what has happens to them???
