The only time the continent has seen stability is during the European colonial period. . . but that was via the sword. It's just the way it is.
Have you ever considered how a few tens of thousands of Europeans (a lot of them women and children) could manage to conquer most of Africa? When the odds were thousands to one?
Yes, they had guns, but as the Russians showed when fighting the Germans in WW2, if you throw enough bodies at the guns, you'll eventually win. And the African settlers didn't have machines guns, tanks, airplanes, or bombs.
I think it went down like this: A small group of Europeans conquered a very small area in a country (as we know it now). Then they set up a city as a European would. With laws, infrastructure, modern medicine, education, and the--then--modern conveniences.
Then those that hadn't been conquered saw that the blacks in that city lived a better life than free blacks had
ever lived. Then those free blacks migrated to the city to get away from the typical Africa level of living. The saw it was better to be second class in a Westernized world, than first class in an African world.
It wasn't until many generations of black Africans had lived under European rule that they forgot how bad it was without the Europeans. Then they tried, and succeeded, in ousting the European rule. Largely because most of the Europeans didn't want to live there anymore (read up on the Belgian colonies).
Then what happened? It fell right back to being the shit hole it had always been when Africans were left to themselves. Look at what happened to South Africa. After the European rulers were ousted, it became the murder and rape capital of the world (the murder capital has since moved to Juarez, Mexico).
And now it's "Oh, great Westerners, come save us!"
Fuck that, and fuck them.
