It’s going to be our fight, we have a lot more assets packing their bags right now.
They must have some broader plan in mind. There were enough SDF to take Raqqa, and enough ISF to take Mosul.
I guess that ISIS is just in for even more of a whipping, and quicker.
They might be going for the stabilization phase, after Raqqa falls.
They might be going elsewhere after jihadis as well.
