Jeff Gettleman has a good piece in the Times about the decline in popularity of al-Shebab now that Somalis get a taste of the viciousness of that organization. I am not going to presume to have any idea how representative the sample of Jeff’s piece is, as he’s in Mogadishu and I’m not. But I note that in 2006, the Islamic Courts Union — which, to be extremely oversimplified, spawned the Shebab after the U.S.-backed Ethiopian overthrow of the ICU — demonstrated real popular appeal. So, not to give into wishful thinking, I’ll just point out that this is the right metric to evaluate the staying power of the Shebab: the demand for it. That’s obviously not a function of popularity, since that reverses the order of operations here: popularity is the indicator of the demand for an movement that can provide security, governance, opportunity, justice and liberty. It is, however, what you want to watch for, since it gives an indication of the durability of anything Shebab does or any anti-Shebab efforts that emerge.
