The ANC was Communist, allied with Communists-they were part of their ruling coalition, IIRC-and Mandela was a protege of Castro.

The Soviets were in constant contact with and overseeing the training of ANC leaders.
Fastforward to now: KGB Putin is using white Boer farmers as pawns by resettling them in *annexed* Crimea. Its Bolshevik land redistribution on his part and there are enough deceived Westerners willing to submit to the propaganda and view Putin aa a savior.
Putin is currently reviving Cold War antics of arming, aiding, and abetting with radical black govts all over Africa from Sudan to Central Africa Republic. Russia continue to seek lucrative nuke deals and ties with the current corrupt South African regime as well.
