"Fear of the Islamic State of Iraq and the Levant (Isis, who now refer to themselves the Islamic State) is the new uniting factor for states in the Middle East and beyond who normally hate each other. The sudden emergence of Isis's still expanding caliphate, with its terrifying blend of brutality, bigotry and military effectiveness, provides a common enemy for the US, Iran, EU states, Saudi Arabia, Turkey and, in Iraq, Shia, Kurds and anti-Isis Sunni."
