Netanyahu is not interested in peace with Syria. He showed it time and again when he ignored Syria's suggestion to have Turkey mediate. Netanyahu continued to ignore Syria's moves even after Syria stated that peace negotiations should be conducted WITHOUT PRECONDITIONS. To this Netanyahu replied by imposing a precondition: Syria should state that it would detach itself from Iran and Hizballah under a peace agreement. A funny reply, considering what Netanyahu thought of Syria's past preconditions. Considering this attitude, I don't believe anything will come of this visit in Damascus, even if it is conducted under Netanyahu's initiative.
