The real victims are the Boers (Afrikaners). The British can return to the UK or the white Commonwealth nations; the Jews can go to Israel. The Boers, descendants of 17th Century Dutch, German, and French settlers, are too long removed from their ancestral homelands. They have lost their native land and will be lucky to find refuge anywhere.
While stationed in Ryadh I delt with a very large number of young South African nurses. Aside from being delightful and good-looking, most were saving their money and planning on settling in Australia. It's a shame, because they'd fit in so well with the US culture.
