A short comment by Richard Barrett, ex-SIS (MI6), who argues we have so far refused to consider this option:
n the wake of Paris, it has become all the more important to determine which returnees present a risk and which do not. This is not only so that authorities can focus scarce resources where they are most needed. It also allows us to identify and seek the help of those that do not present a risk. Many argue that anyone who went to Syria deserves no understanding or mercy on their return; but some of them know that they have made a mistake. They will help us cut the flow of fighters to Syria by helping us understand why they go, why they stay and why they come back. It is these same people who can be more powerful influences than any other on those who may be inclined to join or act on behalf of Isil. Often they have tried it and seen it does not work. They have the credibility and understanding that the rest of us lack. They hold the key to victory.
