You're right, and they're quite effective. Look at the letter the BBC published in its webpage the day after the concerts: "Africa needs a period of 40 - 50 years of re-colonization. This time it should be done right and in such a manner that Africa is left in the same condition at the negotiated end of colonization as Europe is today. This time round the borders of the states of Africa should reflect the Geography and Ethnicity of Africa and not the shape of the coffee stains on a map in a drawing room a la Berlin conference. It is possible. But improbable given the amount of jingoistic "anti-colonialism" bandied about the capitals of Africa.
