After years of revolutionary upheaval, the Arab world is in a state of flux. The old state system is on the verge of collapse. And an increasing number of non-state groups are using arms to achieve their aims.
Most have different ideologies; and some are being used as proxies by regional governments. But all of the region's armed groups have a common source of strength: their weapons.
