israel can continue as far as they want till they can take whole damascus if they want. damascus beyond government bunkers aren't like those in gaza and even that they can just indiscriminately bomb the whole place.  hts doesn't have neither an airforce nor airdefence to resist. pickup trucks can get you so far (especially if you meet someone that is willing to fight this time).  also israel would love to connect with the kurds and also block the qatar turkish pipeline so they can shill the east med pipeline.
