Well, the thing is, Whites have a 100,000 year evolutionary head start on everyone else. While Africans were eating fruit out of the trees because Africa is *extremely* hospitable, Europeans were fighting, dying, breeding, fighting, dying, breeding, in continuity for millennia.
So in the current era of this World Dollar Empire thing, fighting ability doesn't really matter. But as soon as that collapses - which looks like it's gonna be pretty soon at this point - everything is gonna revert back to the pre-20th-century model where winning is the only thing that matters. And that's a model where Whites come out on top.
