What should be noted is this: US/Israeli preference for the Asad's regime preservation of "protected and peaceful" border with Israel is gone, no matter what happens. If the regime survives, it will be a weakened regime with a more weakened security apparatus. And if the Ikhwan (under different names, and hiding behind civilian suits and skirts) seize power, they will be dealing with a most determined and vicious campaign of violence by survivors of the old regime aided by Lebanese supporters of the Asad regime. Either way, Syria will be undergoing a "Lebanese" phase of sorts.
