I’m not British myself (well, technically I am; I do have a British passport - but I was not born in Britain, and can’t take credit for whatever they did for good or bad in the past). Also, Canadians came to the rescue of this island many times, so the appreciation for your people (even the unapologetic separatists) is mutual.
I hope you get what you are looking for, and that all your certainties and convictions about what the world is or isn’t, and what your friendly southern neighbours will or won’t do when world leaders go insane and war-time military conscriptions begin, turn out to be true. The world would certainly be a much better place if rich “farms of the world”, be it in Canada, Australia, Brazil, Europe, the Middle East, etc. couldn’t be bullied in times of need (or at any time, really).
I’m nowhere near as certain of my own convictions or my ability to predict how people will act when push comes to shove. As far as I’m concerned, if I could bring my family members out of Canada at the moment, I would (not that the UK is doing any better at the moment). Unfortunately, I can’t.
