For sure there are channels of covert western military and intelligence support for Boko Haram of the same sort that were served to the Libyan Islamist rebels NTC through Gulf Arab states. The objectives of the West are three-folds:
1- To divert and suppress the public growing hostilities and legitimate demands against western oil companies and their influences (which surprisingly Boko Haram is mute about them!! and no attacks reported against western interests and individual casualties. Those killed in August 2011 bomb attack on the UN House in Abuja were not; 11 were UN personnel almost all of them Africans, and 12 non-UN persons ).
2- To hold the Nigerian Government and corrupt wealthy clique hostages to internal insecurities and conflicts and hence weakening their bargaining position; and advance the need for the rejected U.S. Africa Command (AFRICOM).
3- To create a parallel invisible violent local hands to act as their armed agents for subversion and coercion and change as an alternative to western military base.
Most probably Nigeria is actually confronted by an “Unconventional” warfare with the West; which is in the form of insurgency of particular ethnic group in the north together with perverts from other regions seeking oil money and power.
The U.S. Special Forces Unconventional Warfare Training Circulars explain this policy quite clearly. They are being applied in north and west Africa and in Syria, Gaza, Iraq and Yemen.
Without western companies of oil, minerals, import of goods and export of cash crops (cocoa, groundnuts, rubber, palm oil and other lucrative commodities) there shall be no Boko Haram, no civil wars, and no coups in Nigeria, Ivory Coast, Liberia, Guinea, D.R. Congo, Senegal, Ghana or any other country.
