The whites in SA really need to do some extermination-level fighting back down there if they want to live and survive down there.
Problem is, whites are only around 9% of the RSA population. About the same in Zimbabwe. Can't win any wars with those numbers. So they're in a real tough spot -- very difficult to get visas outta there to safety, and can't win a civil war due to relatively meager numbers and no political power.
