"South Africa, with US support, after the fall of the Portuguese empire, invaded Angola and Mozambique to establish their own puppet regime there. They were trying to protect Namibia, to protect apartheid, and nobody did much about it; but the Cubans sent forces, and furthermore they sent black soldiers and they defeated a white mercenary army, which not only rescued Angola but it sent a shock throughout the continent-it was a psychic shock-white mercenaries were purported to be invincible, and a black army defeated them and sent them back fleeing into South Africa."
