You can give your info to the registrar and then make it anonymous to whois domain.tld
searches so it’s not public. Cloudflare is the registrar I use these days because it’s a one-stop shop and used the company address but, at least in the U.S., they need your info for both credit/debit card processing. (Processing fees are cheaper the more info they provide but usually any address with the same zip code is enough.)
If you have nefarious plans, I don’t have a good recommendation. But if it’s just about privacy, I don’t know if it’s really possible to be completely anonymous anyway. I guess you could use a gift card or something but at least in the U.S., if you own or buy a house, your address is public info already anyway. Shit, city hall will probably give you blueprints of any house.
At this point, I don’t think Russia could win a conventional war with France, much less one they attack France first and it triggers Article 5. I might not have thought that before Ukraine but once you start relying on North Korea for bullets and personnel, you’re down bad.
