The Islamic State Stumbles

December 30, 2014

Last summer, there was widespread hysteria across Official Washington over the seemingly unstoppable expansion of the brutal Islamic State – and handwringing over President Obama’s limited military response – but the jihadist momentum now shows signs of stalling, writes ex-CIA analyst Paul R. Pillar.

The fortunes of the extreme and violent group known variously as ISIS/ISIL/Islamic State seem to have changed markedly during the past few months. This summer the group was commonly portrayed, amid much alarm, as a relentless juggernaut that was scooping up so much real estate that it was a threat to overrun Baghdad and much else far beyond.
But the progress that was so frightening to follow in maps in the newspaper has stopped. The juggernaut has stalled. There will be endless debate about the causes of this change of momentum, ranging from military measures that the United States has taken to the somewhat more enlightened policies of the Iraqi central government. These and other influences have their effects, but the larger phenomenon of the decline of ISIS — decline not just that has happened so far but is yet to come — can be explained most of all by the group’s own policies and practices.
