"Whilst regimes [in southern Africa] have been prepared to declare themselves Marxist and practise Marxian economics, it has often been an excuse to pursue tribal aims. In [Marxist] theory, African society is too underdeveloped to produce Marxist revolution. But the concept of a one-party state provides the perfect ideological cover for asserting tribal (i.e. racial) supremacy. This can be seen in the Soviet Union where the Russians use Marxism-Leninism to justify the repression of what they generally regard as racially inferior groups: the unrest in the south of the Soviet Union epitomises these problems."
