War and imperialism, on one side, and the growing reach of jihadist terrorism, on the other, are said to be locked together in a mutually reinforcing embrace of violence and destruction. “Imperialist cruelty and Islamist cruelty feed each other,” the French Nouveau Parti Anticapitaliste (NPA) argued shortly after the Paris attacks. In order to break this nihilistic death grip, we need to oppose foreign intervention, put an end to imperialist violence, and halt the ongoing plunder of wealth from countries in the Middle East, Africa, and elsewhere.

The basic logic of this argument is undoubtedly sound. But in terms of explanatory value, this kind of analysis does not go far enough. It suffers from too much generality and abstractness — telling us little about the specificity of this particular moment, or the nature of ISIS as a movement. By attributing a kind of automaticity or natural mirror between ISIS and imperialism, we can miss the all-important context and history that has shaped the remarkably rapid rise of the organization.
