I don't think the process of bringing in the Yazidi population is going to affect it one way or the other. I think what's going to affect it are the ongoing military operations and counterattacks by Daesh. Potentially, as Daesh is diminished, there is the potential for the various other groups in northern Iraq to start taking on each other as the situation becomes more fluid.
