The damned Cubans tried to get a foothold, a few decades back,but since they couldn't speak much English, no Afrikaans, and NO tribal languages, they just managed to annoy everyone and got nowhere.
Wrong, the Cubans tried backing the Angolan communists and SA eventually
had to get involved resulting in huge Cuban losses and eventually defeat. The end will come not with farm land appropriations but when the gold and diamond mines are taken.
