Israel has attacked Syria a number of times, previously, and the same threat has been made. The only thing that has prevented such a Syrian response, to date, has been the Israeli nuclear capability. Until now, Assad has been reluctant to risk the destruction of Damascas as retaliation for a strike on Tel Aviv. The question is, does he care more about being in power than the survival of Damascas. Assad's successor will probably be either Hezbollah or Al Queda. Since both celebrate martyrdom, the survival of Damascas would not be a paramount issue, and the danger of an attack on Tel Aviv would be greater, if they ascend to power.
