Iran's policy in Syria has always been a free election under U.N observation, if your info about 80/20% is true, then why F$A wont accept it, why their condition for accepting election is removing Asad from the list of candidates? please refer to your mind, and not your ears. Syrian government accepted changes in political system long time ago, so the Iran's 6 step peace plan, but F$A has no support in syria, from shiah, sunni and christian all support him. and look at his statements about Bahrain, Sadi arabia sends his military to suppress the protestors in Bahrain (I hope you know what it mean) and again he talks about sectarian stuff and supports the dictatorship which even arrested and tortured and ... doctors who were accepting injured protestors.
did you the report from Jordan newspaper about the role of KSA and wahhabis in sectarian incitement in Jordan? this is their job and it wont change, their support for Israel isn't new, and I assure you they will continue it no matter if Iran or Syria existed or not. U.S wouldn't choose them as their number one ally in ME if they had any policy against Israel.
