My point is: the civilian casualties are going to happen anyway. But the only party there I see interested in at least limiting them is the Western coalition. Russia/Assad and ISIS don't care.
And there are plenty of refugees to take in. But not from ISIS stronghold where they are forced to stay and executed for whatever reason on a daily basis.
Assad did what most dictators always do against protests- Push back hard. It's possible that if the western powers had stayed out of it, it would have played itself out with a lot less deaths and less damage to the infrastructure.
It's possible that engaging in the proxy war greatly expanded the misery and suffering to a lot more people.
After all, isn't that why we don't invade and liberate many other countries ruled by just as cruel dictators? The cost of life is high, and only when you can step into to stop an actual genocide- A mass slaughter like in Rwanda, where it has stopped being a civil war between actors fighting for control of their own country, it seems like outside influence doesn't have a positive effect.
