All this is pointless, as they are totally incapable of building an advanced society. The one and ONLY single thing those people know how to do, is slaughtering one another – unless they have a totalitarian regime (like in rwanda), which suppresses it. Look at south sudan – for decades we heard, how "those poor chistian people do only crave their independence from the evil muslims, to finally live in Peace"… but then, right after receiving their independence, THE FIRST THING THEY DID was starting to brutally slaughter each other.
Also, no wonder the rwandans are christians; which other faith could POSSIBLY have taught them to become mass-murderers, if not THE most blood-thirsty and genocidal faith this planet has ever known?
OF COURSE there is a way for them to prosper; BUT they shall never choose it. They shall forever insist upon bringing WAAAAAAAAAY more children into the world, than they could possibly support and spend ALL their money on weapons, while whining and blaming the "evil white colonialism" for their own inherent stupidity.
So, that ridiculous union shall amount to ABSOLUTELY NOTHING; just the same as the "african union" (remember it? It exists… theoretically… so???). Just, some power-crazy dictators, having their photo-op… and ABSOLUTELY NOTHING besides.
