I don't think it's about the persecution of minorities. It's about the persecution of anybody who doesn't think like them. Unfortunately, it looks much worse to minorities because they cannot defend themselves. Not being able to defend yourself, you have to flee. That's what happened in Mosul. That's what happened in Qaraqosh in August where all those 120,000 people left. They had no way of protecting themselves. So it looks very bad. It looks like they're attacking minorities because they happen to be there. But the next day, it's going to be another group of people. Even many Sunni tribes that were supporting ISIS are now becoming the victims. Their mosques are being destroyed. That was not part of the deal.
