What is likely to happen is Zulu and "Boer" versus the Communists, with the world press cheering the Communists on. My money's on the Zulu.
Both the Zulus and the Boers fought each other in the past. They have respect for each other based on that conflict. They are natural allies against the ANC. The chief does have a point. The food supply of South Africa is being threatened by government policies. The nation is slipping into civil war.
