Boko Haram and Ansaru fought with AQIM & Ansar Dine in Mali. Some of these groups have spread to Senegal since the French intervention a few years ago since they view the French and any of their fellow travelers as infidels.
As I stated earlier, ISIS wants to gain more power on the African continent by allying with African terrorist groups.
It's preposterous to believe, for example, that Boko Haram is part of any agenda besides conquering Northern Nigeria and killing Christians.
So far, you and OP who have alluded to a conspiracy (that somehow you know since it isn't a well kept secret but you two are ON IT) that hasn't even been explained on this thread.
No, I'm not willing to entertain it.
