US president Barack Obama is leading an international effort to “degrade and ultimately destroy” the Islamic State in Iraq and the Levant, known as ISIS or ISIL, which has occupied large swathes of Syria and Iraq. The US has attacked the terrorist group in both countries; it will also train Iraqi Sunni forces, and support Syria’s moderate opposition. Success, however, could depend on the ability of the West and its Arab allies to co-operate – at least informally – with Damascus and Tehran.

ISIS poses a threat to Europe. The group has promised that some of the approximately 2,500 European fighters in its ranks will return to attack European targets. A number of ISIS-inspired plots in Europe have already been foiled. In July, eight EU states agreed to share intelligence and co-operate to apprehend returning fighters, and to stop ISIS from recruiting in European cities. At the European Council meeting in October, the remaining 20 member-states should also sign up.
