There doesn't seem to be a solid purpose to driving every successful African state to chaos & poverty. Expanding communism may have once been the goal, supplying bodies & resources to fuel more communist expansion. But that (as far as I know) was contained to Africa.
The three objectives I can see are: denying other nations the resources of Africa, a powerful source of destabilization that can "used" by dragging nations in or moving people out and building upon the results, a massive wealth theft & "redistribution" mechanism through which individuals & organizations gain power & wealth and unsustainable governments are funded.
This can't be random, not with the U.N. and communist countries doing the exact same things, over and over.
Have we witnessed large-scale socialist experimentation ?
According to them, the only thing holding back African countries is Colonialism and Racism.
Therefore, when Black African leaders repeatedly fail, and drive their countries into pre-colonial poverty and violence, it *must* be caused by colonialism and racism.
So they just keep on doing the same stupid things, over and over.
