Part of the problem is that he isn't even internally consistent.
Sudan is too large, and should be split up. But also: "Africa can become economically viable only if its plethora of puny economies merge from more than 50 into just a few."
So what needs to happen? Merging Africa into a few gigantic balkanized states with no shared interests (like Sudan), or splitting it up into many small city states, a few of which will be well run?
A few of which will serve as an example for the rest.
But this: "Merging Africa into a few gigantic balkanized states [...] or splitting it up" is part of the reason they're doing badly. Being a battleground for foreign intervention has not allowed much in the way of economic development.
