...what, than the current one which funds, trains and provides shelter for elements of Hamas? I'll also point out the more [relatively] democratic models of Egypt and Jordan who manage to be friendly with Israel.
IMO the danger is an Iranian-style hijacking of the country by fundamentalist nutcases - and Syria and Iran are very friendly - which could easily whip-up anti-Israel sentiment Hitler 1930s-style.
The difference between what we have now in Syria and what could come is Syria presently wants to stay a member of the world community; get some sort of Ahmedinajad/Chavez/Kim Jong-Il in character and it could get awkward, esp. as Iran has been giving Syria missile and possibly nuke technology.
