When I was saying we had no business getting involved in Syria when this was floated by Obama, the reason was that Assad was the typical badass ruler over there who kept the tribal factions jostling for power tamped down by being the meanest mother in the valley.
One of the benefits of this, though, was that Christians were as protected as any other group. Everyone play nice or heads get knocked (or lopped, or whatever), but they were going to tolerate each other or he'd kick their butts.
Unlike the MB inspired Muslims that took over other Middle Eastern countries after they were destabilized (likely with help from our Department of State under Hillary, et. al.) where Christians were being beheaded, herded into their churches, sealed in and burned with the church--in Syria, Christians were relatively safe under Assad if they weren't causing trouble.
