Africa's main problem is over-population, and this causes intense rivalry over food supply.
I've seen rival tribes in Africa living side by side without any social interaction, but without strife, also, as long as there is enough food to survive.
In ancient times if food supplies were limited, one tribe raided another tribe and killed off half of them and stole their food. That mechanism controlled the population.
The Western world abhors the wars of genocide, but it's always been a part of African life, much as it was for the American Indian before the white man wiped out most of them.
Another contributing factor to the problems of the Africans is the idea buried deep on their primal pons that they should be able to live off the land.
A case in point:
While I was driving my Fiat back to camp one night on a long board road in Nigeria, my driver who had reluctantly allowed me to drive, spotted a small animal crossing the road.
He became very excited and told me, "Stop, boss! Good chop!"
He jumped from the car and, with a small club, beat the animal to death. He brought it back to the car with the air of a mighty hunter. He showed it to me with, "Good chop, boss!"
Now, it didn't matter that he had all the food he could ever eat at camp. What mattered was that he had killed his own food from his own land.
The problem with that idea is that there are practically no animals left in Nigeria, and in many places in Africa.
They live on a high carbohydrate diet of tubers. If they're lucky enough to live by a river they have fish to supplement that diet.
When the Western world seeks to "help" Africa with donations of money and food it must be kept in mind that the tribal need for their own land will not be diminished simply by having enough to eat.
It will not stop genocidal wars; it will just make the warriors better fed.
