As a sidenote, I remember that UK has an odd and ancient “law” stating something in the lines “” (i.e. being anti-monarchy and advocating for the end of monarchy, even without any violent language/means but a pacific defense of anti-monarchy). I couldn’t find it, nor I can remember the exact phrasing, but such a “law” threatens prison time for those who “dare” to “offend” the crowniness of UK Crown. Also, I’m not sure to what extent this law is applied in practice.

Given there’s an active pro-republican campaign site I’d wager not at all.

If countries are capable of passing draconian laws against their own citizens, don’t expect that those same countries couldn’t go further to impose these laws beyond their own lawns, especially in times of interconnectedness.

UK against the USA? I think the UK isn’t winning that.
