The only thing Hezzbollah is good for is gunning down civilians, selling drugs, and extorting money
Now Assad has his two main backers either rendered useless or occupied in Ukraine.
The Russian Navy won't be showing up in the Med, the Kuzentzov is in drydock.... Possibly forever, and the Russian military is down ~115 helicopters and ~90 jets vs 2015/16 and every cruise missile they make is earmarked for Ukraine or domestic reserves.
The Alawites lost BADLY in the Civil war so far. They're not going it be dying in Aleppo, id doubt most will leave the Alawite stronghold provinces. Syria is an economic disaster zone so Assad can't bribe them, or ANYONE to fight for him.
Iran is also and economic basket case and can't pull the same number of Basiji, IRGC and Afghan/Iraqi Shia volunteers as they were burned through from 2011 till 2020
