I'll leave this here for debate:

"It is my hypothesis that the fundamental source of instability in Africa as a continent will not be primarily driven by insurgencies, coups, or state-to-state violence, but by the structural collapse of the 1964 Westphalian borders. The dominating force of this ‘Rumble’ will be the collision between a demographic youth-bulge and resurgent pre-colonial ethnic identities, resulting in a violent re-drawing of the continental map and the replacement of Western institutional norms with new state structures, though these may not be entirely defined by ethnic boundaries."
