To be fair, "the Afrikaner" was hounded, badgered, sanctioned, excluded, pressured, pushed and boycotted into doing so, including by people like me. My own motive was that they abandon the racial discrimination that prevented black people from owning property, attending schools and generally living and working permanently in large portions of their own country. Apartheid laws were in force for 40 years -- from the Population Registration Act of 1950 to the de facto scrapping of apartheid by de Klerk in 1990 -- and that grievous injustice has become the rod with which we are being beaten today and will be probably forever, or until the Revolution. They knew what was happening elsewhere in Africa - that was the reason for apartheid. Their intelligence services certainly knew what the ANC and PAC cadres were, but local and international events overtook them. In the end, a combination of internal and international pressure and their own conscience that racial discrimination is morally wrong got the better of them, they capitulated, surrendered power, and the ANC swept into government.
