A state of terror: Islamic State longs to be left alone to establish its blood-stained utopia

The Sykes-Picot agreement will be 100 years old next year, but there will be no congratulatory telegrams winging their way to the Middle East from London, or from Paris on high alert. The Islamic State, the world’s most powerful jihadist group, has filmed its men bulldozing border posts between Syria and Iraq, dealing perhaps the final blow to those Anglo-French cartological ambitions of a century ago.

The ‘Caliphate’ is inhabited by some six million people and is now larger than the United Kingdom. In the words of Patrick Cockburn, ‘a new and terrifying state has been born that will not easily disappear’. Yet far from appearing out of the blue in 2014, IS was fostered for years by those who profess to oppose it, as this book argues convincingly.

Cockburn takes aim above all at Saudi Arabia for promoting Islamic fundamentalism; and at Turkey, so desperate to topple President Assad of Syria that it turned a blind eye to Gulf-backed foreign fighters crossing the Turkish border.
