Putin's clients include Assad, a secular Muslim who protects Christians (as did Saddam, another secular Muslim who was overthrown by the Neocons).
Assad has zero money to offer Putin.
He’s supported just to rent a destabilizing force.
But, yes, there are zero “good guys” in Syria at the moment, I fully agree. Just various shades of crap. Maybe the Druze are OK, but that even depends on the tribe.
