People do this kind of underhanded passive aggressive thing all the time, why would it not be the case for the British government to basically “neg” the VP that has on several occasions now dressed them and all the Europeans down and embarrassed them?

You seem to have a “police state” model in your mind that is akin to a North Korea and less what it will most likely be in the west, far more manipulative and sophisticated, as depicted in Orwell’s 1984.

Spend a few months in Azerbaijan if you want to experience a police state. I have :)
