I don't know, probably a big one that can make a commitment. Have you tried using your own imagination?
Seriously though, I often don't think there is a solution. That entire ME region is thoroughly hooped and there's not a damn thing anyone can do about it. It'll just be a perennial state of hatred death and destruction - its just another big mess we'll have to leave to people in the future to figure out.
So what's your wish?
