It is not the Arap Alawaites, but the Iranian faction of Shiite groups and elite groups that have been deprived of their "eliteness" that can finance mercenaries. They also don't refrain from hiring militias disguised as the armed forces of the new Syrian government and provoking local groups with the pressure.Sooner or later, the Alawaites (pro-Assad faction), will rebel against the current govt
It seems that they cant digest the fact that they arent the kings of Syria anymore
I expect more sabotage attacks within the Alawites community in co-ordination with Iran and the PKK in order to create chaos within Syria
Iran doesnt wanna leave completely defeated it seems and it will do so through its proxy, Hezbollah, who seems to have re-organised their ranks and began infiltrating Syria again after their failure against Israeli advancements
Iranian militias take shelter in YPG / SDF occupied cities and travel freely to any desired city, both Israel, US and West watch this happening and only for the sake of destabilizing the rest of Syria.
While the West can theoretically end Iranian influence in Syria / Lebanon and cut off all border access, in practice they are using their arch enemy as a balancing power against Turkey and related groups that favor them.
As it seems, for sake balancing power of a NATO member, they favor free reach-out of Iranian militias through YPG.
