Your quote is the crux of this article. Even after Machel recognized his error and warned Mugabe against it years ago, the destructive itch eventually got to him.
We have been lucky so far but how long will it be before the ANC develops this same itch. Perhaps JuJu will do it for us.
After 20 years, the economy is still controlled by whites in SA. We still have "White Suburbs" and "Black Squatter Camps". Nothing is changing and I don't see it changing in the next 20 years. I think the ANC realizes this and will eventually have to force a change to get the demographics into equilibrium.
Scary stuff.
