I'm not an expert on the region. My opinion comes from the fact that Rhodesia fell in 1980 & SA held out until '94. I've been to SA and have Afrikkaner friends. I'm not condemning any african whites for what happened, it must be hard as hell to be outnumbered 10 to 1 at home and having the whole world against you as well.
I worked in eastern Africa for almost two years with a bunch of "Safricans" and people from Zimbabwe as well. They are incredibly frustrated at the lack of interest from the rest of the world...they would constantly complain that if this were happening to blacks by whites, the UN would be occupying Joberg and Capetown.
