The EconomistThe self-proclaimed caliphate of Islamic State (IS) is weakening fast. In June the jihadists were kicked out of Fallujah by the Iraqi army, then pounded by air strikes as they fled. American-backed rebels in Syria have surrounded the group's fighters in the northern city of Manbij and are eyeing Raqqa, its de facto capital. In total, IS is now thought to have lost half of the land it seized in Iraq and 20% of its territory in Syria. It is on the verge of losing its main stronghold in Libya, too.
