Well, the OP says either 19th or 20th century... so what if there's some kind of French collapse after a CP victory?The Maghreb was the target of Colonial desires from every Mediterranean nation, especially France. Uniting at all would be hard, as France and the Ottomans would try their hardest to stop it. Even if they united, I doubt that would do anything but delay France, and give them more land once they kick down the door.
