Davidbfpo,

Personally I cannot see African governments agreeing to an African NATO, nor would the UN take responsibility. Africa does have a number of professional militaries, equipment is another matter, let alone having the airlift, mobility and more to act.
Paul Collier hasn't asked the most important question: why do these rebellions occur in the first place?

Africa isn't Europe, with fully formed states & an established order. Africa is a continent of failed states & states on the verge of failure.

Let's consider Nigeria - it has too full blown insurgencies, one in the Niger Delta & another in the North East. How would an African NATO address the conditions that led to these insurgencies in the first place?
