The real reason White South Africa fell was because it failed to uphold God's law of extermination of mongrel races. Unfortunately the British (jewish empire) run colonies forced integration of mongrels and recognized as "people" while the soft-hearted Boer Transvaal, in spite of their troubles with the niggers during the Great Trek, couldn't bring themselves to exterminate them either.
In humanist terms, it was the betrayal of fellow White countries at the behest of jewish media, combined with the betrayal of FW De Klerk which led to the White people of the country literally handing themselves over. The irony is that there was never any military threat to the South African Defense Force or the South African Police Service. In 1994, if they wanted to, they could have wiped all the niggers out no problem.
