Everything you said is true: Israel had withdrawn from Lebanon completely in 2000. There is nothing left to "liberate" in Lebanon. Lebanon had nothing to fear from Israel, but everything to fear from Syria and Iran. Iran, with the present regime in power, will never give up its proxy war against Israel, not unless it was forced to do so. Except: "The argument that if only Israel gave back the Golan to Syria, Syria would rein in Hezbollah, ignores all precepts of international law. Syria cannot use Lebanese territory and a terrorist proxy of a third country, Iran, to advance its strategic interests." Not true: Syria can, and proves it can everyday that passes. But Syria, under the present regime, has too, like Lebanon, everything to fear from a shiite fundamentalist Iran. The present partnership between these two, in activating Hezbollah against Israel, is only ad hoc and temporary. There is no real strategic and geopolitic Syrian interest to stay in a state of war against Israel, no more than Egypt had, or Jordan. The moment Syria gets its Golan back against a real peace and normalisation with Israel, it has no reason at all to go on playing the Hezbollah card against us. On the contrary, it has all the raisons in the world to stop giving it its blessings.
