I believe this isn’t 4D chess in which he makes a snide remark about South Africa again, but Cyril Ramaphosa signed a controversial bill called Bela or Basic Education Law Act where the ANC wanted to give more state control and give less control to school governing bodies, in regards to languages being taught at schools. Many Afrikaners, myself included, ( just Google Pretoria girls highschool of you want to read a rabbit hole of government overreaction) felt this was a ploy to try and exert control to try and dictate which languages should be taught wat school, such as choosing English over native mother tongue languages (like suppressing Afrikaans for example). There are merit and drawbacks to the bill, but even if Trump is obsessed with us white Afrikaners in South Africa (sarcasm), I do not think this is what he meant, and if he did, we would like him to allow us to deal with our own issues through dialogue and democratic methods
