Botswana is reasonably successful, and I chalk that up to less focus on revenge plotics (the idea of making amends died alongside Mandela in South Africa).

What's truly heartbreaking is how almost the whole continent has been strong-armed into colonialism. In South Africa, that's Anglo-Plat. Zimbabwe (my birth country) has been completely colonialized by the Chinese and is being stripped of everything (with no expense, much of the beauty of the country is gone - e.g. the Chimanimani mountain range).

Revenge isn't worth it.
