When Isis comes home
The Islamic State’s pretence to nationhood was based on the holding of territory. With the battle for Mosul this week, together with the loss of the land that it controlled in Syria, that pretence is becoming harder to maintain. The area involved is now limited to a few shattered cities, and corridors between them. The decline of this terror organisation is to be welcomed. But this is a war which can have no neat ending. If Isis were a genuine state, it would by now be forced to consider unconditional surrender. That is not going to happen. More probably it will dissolve, its leaders and lesser agents making an escape
