It's a matter of tactics and strategy. Immediate mass murder would have been a fun tactic (per Alinsky, use tactics your people enjoy) but a failed strategy as it would invite foreigners to intervene.
So, Mandela put on a winning face, and went for the slow route. Put blacks in all positions of power, and then ignore any atrocities that might happen to whites. Sort of like how Eric Holder ignores any crime sprees against whites in this country.
Having the lowest and meanest of your followers do your dirty work leaves clean hands for Mandela, and for Holder/Obama.
That’s a good description of all this Mandela business. Whites who were in the know cleared out of SA as fast as they could, leaving behind the people who believed Mandela’s lies about being safe.
I know people in the “cleared out” category, and they are sad for the homeland and friends murdered in the pogrom.
