The Christians are bound to support continued Syrian interference. Number one, once the Syrians are out, Hizbollah is going to run wild in Lebanon, as the proxy of Syria, and bring on another civil war. The last one didn't go well for Lebanese Christians. Number two, Walid Jumblatt and his Druze militia helped dismantle the pluralistic state that was pre-PLO Lebanon (acknowledging of course that the Moslem terrorist paramilitary -- such as it was -- with Syrian assistance helped bring down the similar arrangement during the 1950s) and had no intention of allowing any Christian voice in the post-Syrian Lebanese gov't.
Civil war it is.
Syria is in bad shape today. No way to send troops or weapons to Lebanon which is under international scrutiny.
Hizbollah could not go wild, they are contained in a political process which will define their whole future, though they created lately an unsolvable piece of puzzle. They claimed, besides Shebaa farms , seven villages in the Northern part of Israel that are legally and historically out of the internationnally recognized border of Lebanon. I think that this is a deceptive maneuver aimed at gaining internal support in front of the UNSCR1559. So if this maneuver comes to execution, they will have to face anihilation, nothing less.
