Not a single country in the world. The ruling elite of all European-majority states, except maybe Orania (a small town in South Africa) are clearly against Whiteness as a concept. Even the third world is more pro-White than these "White" countries are. Seriously, if you go to India then you'll be treated as a God amongst men in certain places there. If you try to form a White identity today then you're a racist, bigot, oppressor etc. because (((Leon Trotsky))) said so 100 years ago in his Communist schizo rabbles. The closest you'll get is some European states like Hungary and Belarus which refuse mass immigration, are somewhat conservative and with a decent national identity (with a decisive European majority as well)
If you're only looking at the current demographics... Then I'll say the whole of Europe and some scarce parts of America are White countries since they maintain a European majority. Obviously America isn't a White country anymore though, since the amount of PURE Europeans is literally below 50% now (Ashkenazi jews and muttified non-pure Whites make pure-Whites an ABSOLUTE MINORITY in today's America) and more Whites die every day than are born in that dying shithole country we call "The United States of America"
