I'd like to test the assertion that (impliedly many) of the kidnapped schoolgirls are Xtian. AFAIK the school that was primarily raided is an Islamic school and the pupils there were observant and in Islamic dress.   This I have from some Nigerian friends one of whom went to university not far from the school.

What MAY come out of this, when Boko Haram attack more Yoruba, is a tribal war. The majority (not all, but, I am told, a majority) of Boko Haram are Fulani. Keith will have a handle on the colonial history but AFAIK the three main tribes at the colonial time were Yoruba, Ibo, and Hausa. When rule was handed over on decolonialisation the Hausa got most of the plum jobs and power. The Fulani got, I think, the shitty end of the stick. Hence, perhaps, their search for a pathway to power - but none of which explains the sources of their funding.
