The New Yorker's Alexis Okeowo reports on the social and political factors that have allowed this mass kidnapping to occur. 

The circumstances of the kidnapping, and the military’s deception, especially, have exposed a deeply troubling aspect of Nigeria’s leadership: when it comes to Boko Haram, the government cannot be trusted. Children have been killed, along with their families, in numerous Boko Haram bombings and massacres over the past five years. (More than fifteen hundred people have been killed so far this year.) State schools and remote villages in the north have borne the brunt of Boko Haram’s violence this year. The group is believed to be at least partly waging a campaign against secular values. The kidnapped girls were both Christian and Muslim; their only offense, it seems, was attending school.

Last June, I visited Maiduguri, the capital of Borno state and the birthplace of Boko Haram, to report on the insurgency and the Nigerian government’s counteroffensive, a security operation that placed three northeastern states, including Borno and Yobe, under a state of emergency as troops launched attacks on terrorist hideouts and camps. The military cut phone lines and Internet access, and, while residents were glad for the intervention, there was a sense of living in the dark. Gunshots, a bomb blast: was it Boko Haram or a military attack? Were the hundreds of men disappeared by the military actually terrorists—even the young boys? And was the government, as it claimed, really winning the war?
