Should Assad of Syria sign a peace treaty with Israel, he would sign a death sentence for his own regime and for himself. Why would he do that? None of Israel's hostile neighbors want peace with Israel. It's a MUST for them to unite in their hatred towards Israel and the west, in order to keep their own dictatorships intact and keep their own population down. Only if the regimes should fall and their populations would be allowed free expression and human rights, there could be a possibility for peace talk.
