The African Alliance did not have a unifying figure or a protector figure that could stand up to protect all the interest of the Alliance
African Alliance do not lack heroes. All over Africa there are great talents. But these talents all fight for their own interest and they care about their own like and dislike
The world had changed but certain tribal hatred could not be forgotten. Past mass murder is repeated again
The oppressed now become the oppressor, not learning from past example.

To have someone like that, it would require a virtuous person.
The thing is, politics is like a poisonous swamp for virtuous people. They could not last long because politics is not for sane people.
