The purpose of the ICTI would be to investigate and prosecute Israeli war crimes, crimes against humanity and genocide against the Peoples of Lebanon and Palestine--just as the ICTY did for the victims of international crimes committed by Serbia and the Milosevic Regime throughout the Balkans.
The establishment of ICTI would provide some small degree of justice to the victims of Israeli war crimes, crimes against humanity and genocide against the Peoples of Lebanon and Palestine--just as the ICTY has done in the Balkans. Furthermore, the establishment of ICTI by the U.N. General Assembly would serve as a deterrent effect upon Israeli leaders such as Prime Minister Olmert, Foreign Minister Livni, Defense Minister Barak , Chief of Staff Ashkenazi and Israel's other top generals that they will be prosecuted for their further infliction of international crimes upon the Lebanese and the Palestinians.
Without such a deterrent, Israel might be emboldened to attack Syria with the full support of the Likhudnik Bush Jr. Neoconservatives, who have always viewed Syria as "low-hanging fruit" ready to be taken out by means of their joint aggression. If Israel attacks Syria as it did when it invaded Lebanon in 1982, Iran has vowed to come to Syria's defense.
And of course Israel and the Bush Jr administration very much want a pretext to attack Iran. This scenario could readily degenerate into World War III.
