At this point, it should be pretty obvious to white people that the time to get out was yesterday. Seriously, why would any white person still remain in Zimbabwe?
Really, there is probably no long term safe place for whites anywhere in Africa. South Africa will be the new Zimbabwe in a few years.
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.
