The Jordanian city of Maan is boiling. Three hours of bad road south of the capital, Amman, this underdeveloped and economically depressed tribal town of 60,000 has long been a locus of anti-government protest. But lately the natives have been particularly restive. Last June, so many locals were firing automatic weapons at the downtown police station that a decision was made to move the headquarters out of town. More recently, violent clashes between Maanis and the gendarmerie have become so ubiquitous that a tank has been stationed along the highway at city limits. Endemic unemployment—believed to be more than 30 percent—is a big part of the problem. So is criminality and hair-trigger hostility toward the central government. Worse, the city’s residents are armed to the teeth, and misunderstandings routinely escalate to Hatfield-McCoy proportions. Perhaps most troubling, however, has been the unprecedented growth of the Salafi jihadist movement in Maan.
