South Africa is different. It is home to the White Tribe of Africa aka Afrikaners. They’ve been there for nearly 350 years and they’ve circled their wagons before and they’ll do that once again if necessary.
I spent a couple of months in Zimbabwe in 1985. The white Rhodies even then, a quarter century ago, were trying to liquidate their assets. Some went as far as Australia, others to nearby South Africa, and the majority went back to Europe (UK or Ireland). I shudder to think what’s happened to those that thought they could outlast Mugabe’s madness. Rather like those Jews who believed that the Nazis would eventually see the error of their ways and leave them alone.
