Assad is not stupid enough to retaliate to something like this because the last thing he wants is for things to escalate and he will be having to fight Israel as well. After Israel bombed his nuclear reactor in 2008 he wanted a diplomatic solution so he could save face but not take on Israel so if he is not going to retaliate to something as serious as that there is no way he is going to retaliate to this especially considering how unlike in 2008 he is now fighting for his survival.
4. AS LONG AS THE IRANIAN MULLHAS ARE ON ISRAEL BORDER,
IRANIAN JEW ,
there will not be peace for Assad and his masters. Anyway, the show in Syria is created by Russia in order to milk the mullahs fro guns. If they atrat the fight with Israel, they know fight is going to be over very very soon.
