Assad has been around for a long time, but now he’s a humbled and weakened Assad on life support from Iran and Hezbollah.
I say its a good situation for Israel. The Sunni states won’t care what Israel does to Hezbollah and Assad won’t be a threat for a long time.
Assad will totter on for a couple of years, but the divisions which were already present (and have been for centuries) are not going anywhere, so his best-case scenario is to maintain control over the enclave where most of the Alawites are clustered. And like all Muzzie despots, he’s leaving Christians to their own devices.
