Trump cuts aid to South Africa over ‘racial discrimination’ against Afrikaners

Incorrect. If all black people were killed, then discrimination would end. Your scenario involves Afrikaner corpses, which are white and therefore worth 10^N with N -> \infty of "the blacks". Thus, you cannot trivially cancel 0 dead Afrikaners with anything except a similar number of Israelis.

Excuse me while I puke after typing that, but I live in SA.
