The centre of ISIL is Raqqa. Whilst its unfortunate -it needs to become a place where life doesn't exist . So rather than small targetted strikes - its more a case for multiple B-52 strikes. We cannot remain in this dream that ISIL have any ideas of meeting at conferences or adopting standards .
If we do not deploy overwelming force - they will become a continual threat
to the Middle East and the West.
