Hezbollah leads fight to retake Syria’s south

 "The south is one of the last remaining areas where mainstream, non-jihadi rebels fighting President Bashar Assad have a foothold."

 That's why Assad gets Hezbollah to fight them, not Jabhat al-Nusra in the North or ISIS in the East. They are murderous scum. The quote does underestimate how much the mainstream rebels are in almost all parts of Syria, and have support greater than their numbers. And the south is quite a foothold. And the Syrian government and its partners lie constantly about how succesful their military operations are, and who the targets are, so we'll have to wait and see if they can reduce any more of Syria to rubble which seems the only success they ever achieve.
