I’m expecting them to support a new “legitimate” government which will turn out to be worse than ISIL and join up with aliens to commit a multidimensional extermination of humans.

If the US can become the common enemy that finally unites all the various factions then that seems like a real improvement for the region. Maybe not for the US, though.

I don’t think there is any entity alive big or small that could find a way to bring peace to the middle east.
