This isn't just protocols, though. At least to me it sounds like an announcement that they plan to "cut the lines" to countries that don't adhere to the standards of the current American administration. A new protocol won't allow you to communicate with people in the United States if you're on a "blacklisted" comms company's network.
Well that's not how the Internet works. Perhaps they can blacklist prefixes from being accepted by American ISPs, but as long as ISPs peer with any ISPs from outside of the country, those advertisements will be coming in.
It sounds like "clean" American ISP's won't be allowed to peer with arbitrarily "unclean" service providers of any kind or else risk losing their "cleanliness" designation.
