Countries don't turn their backs, people do, and I don't even think they are. No one wants to spend 10M sats on a first class Delta ticket to ATL while rectally inspected by pmarca's spy AI and then ultimately detained at the gate because according to their twitter feed they're not in the business of sucking orange pipi.

Just a few days ago there was a TV warning not to travel to the US as new visa rules come in requiring applicants to disclose their last 5 years social media posts. Commentators were comparing this to the rules applied in autocracies...not democracies. You can even get approved the US visa but then have it withdrawn once you are in the US on your travel and so then have to immediately return home. This new rule appears to apply to countries previously considered friendly toward the US.
