Many whites in SA can trace their lineage back 300 years or more...it’s their home. Just like America is our home, regardless of who was here before us.
To avoid a ‘hot war’, the best they can do is start a slow, generational migration to the west. With new technology, living in the desert/savannah is easier than it once was. Of course, each family should have as many children as can be supported to keep the demographic needle moving in a more advantageous direction.
Wouldn't that sort of defeat the purpose of an outward migration?
