I just can't see how both Syria and Israel would support the same side in Lebanon. It doesn't make sense.
I know that sounds odd - and it conflicts with our view of Syria as an enemy (AND THEY ARE AN ENEMY) but I want to point out that things are not simple and clean in the Middle East. Syria may be a repressive regime - but as you saw from my Pope post above to you - it is the only Arab country where Arab Christians not only feel free from persecution but feel they are equals with Muslims.
Again, I know this confuses the Syria is an enemy issue - and I stress again Syria is an enemy - but beware what our actions against Syria will mean for Syrian Christians and secular Muslims.
