The Idea shuld be clear if you place yourself as the Syrians here: With experience, the Syrian have always lacked trust in Israel. Syria would hardly place the extremly high risk on their current relations with these parties and Iran for a peace process which can possibly fail. Syria instead makes a bigger leap towards Peace and more of a proof of good intentions, which is having an embassy in Israel, usually one of the final steps in a peace process. Israel would also place its peaceful embassy in Damascus. This would have both parties obligated to move forward, with little chance for bad surprises. Meant to be hard to swallow, Israel will perhaps give part of the Golan, secured by the US (which Israel cant hit like UN forces) in return for embassy exchange... Then Negotiate a peace settlement with all these groups through Syria. A Peace agreement with Hamas, Hezbollah and Syria means an Iran without reason to attack or threaten Israel, hence chance for settlement with Iran.
