I’m not at all sure about Vlad Putin’s faith, but it is a very clever tactical move. Russia desperately needs to reverse the population decline, improve the bloodstock AND provide a sturdy buffer between the Russian heartland and the Muslim south. Boers will do all of that, with ease and competence, and they have money. It makes a lot of sense for both parties. Africa as a whole, from the top to the bottom, is heading back to where they were before colonization.
The world is a sad place right now. Only Western Civilization transcended a brutal human existence, and it is now consuming itself (almost has) in an orgy of PC, feminist, global warming, vegan BS. The vegans will signal the end of the Age of Smugness by fighting over dead rats.
Meanwhile the planet has entered a new ice-age. Nature has myriad ways of solving overpopulation problems.
