Senior Chief Petty Officer. Starfleet is in my blood, and I've spent my entire adult life in service to boldly going.
Keiko and Molly are my favorite humans, but Transporter Room 3 will always be my favorite.
Just don't ask who what's in the pattern buffer.
Tldr: Long winded way of saying "is he wrong to assume that?"
American here, I can assure you that the majority of the people around me have absolutely no idea about anything involving the UK government.
In the last month I have overheard two separate conversations in different states, asking if the UK has a "president", and at least one got the answer "no, they have a queen".
I'm not even sure most Americans are aware the queen died. I'm not sure how they could possibly have missed it, but our country is collectively under a rock, so...
I have heard many people over the years trying to argue US law for things happening in the UK.
I have had to inform a great many people that the UK includes Wales, Scotland, and Northern Ireland. Most people have been surprised to find out Ireland isn't united as a single country.
Americans in general are not smart. Even less informed about anything that happens outside the US than I assume most people in the EU know about the US state Ohio.
