Or could it be because African concerns do not reach out beyond their borders? No Africans have flown a plane into buildings, strapped bombs on themselves and blown up in marketplaces, etc., etc.
It is a shame indeed that terrible things happen in Africa and around the world. If you think of the planet as a physician taking care of patients then what is being done is nothing more than triage. Taking care of the worst case scenarios first and those that impact less later.
