Playing Ostrich about Islamic Extremism in Nigeria

In CSIS Richard Downie writes

The threat posed by Islamist militancy in Nigeria is first and foremost a threat to Nigeria itself. This is a large, chaotic, and badly governed country split along ethnic and religious lines. A predominantly Muslim north and a predominantly Christian south coexist in a permanent state of tension. Furthermore, the north is chronically underdeveloped and home to a mass of unemployed and restless youth, who, if the experience of other countries is anything to go by, tend to be vulnerable to extremist messages. Nigerians might be right when they dismiss the Abdulmutallab case as a one-off, but they would do well to guard against complacency.
