They fight each other. There is no western influence or exploitation. Islam is responsible for many of the conflicts in Africa but greed, violence and lust for power are also causes.
The United States Bill of Rights and Constitution was the last serious attempt to form a government that accepts the nature of humans to turn into warlords, kings, queens, Princes, dictators, emperors and the carnage they bring.
These documents were the pinnacle of European thought and American Colonial desire for a government free from the shackles of totalitarian authority. It took centuries of experience and thought leading up to the writing of these documents. Read up on the English Civils Wars, French revolutions and countless other uprisings in Europe.
Sadly these timeless ideas are being forgotten and discarded.
Once Christianity and Western forms of government fail then it's going to be hell on earth like in ancient times.
