I think the United Kingdom is the most culturally rich, historically valuable place in the world. They've definitely earned their place at the zero point of longitude, latitude, and time zone divisions. I believe they've outshone even the Roman Empire. If they could have held onto Australia, Canada, India, and Ireland, they would probably be a superpower to this day.
It wouldn't be much of a stretch to say that they are probably the best nation ever to walk the face of the Earth, and that many of their former colonies are a close second. They leave thriving civilizations in their wake, they've worked to spread capitalism, democracy, and the English language all over the world, and they are one of the most generous countries with foreign aid. I really don't see how anyone couldn't like them or their culture.
I think that every nation in the world should strive to be more like the UK. It should be considered the standard against which all future nations are compared. The world should look to it as a role model, essentially. Pretty much every country they've ever colonized has been left better than they found it, except maybe some of the African ones... but aside from South Africa, there aren't really any successful nations on that continent anyway.
Actually, yes... all of that is contained in my first thought. I've read so much history that just hearing the name mentioned causes all of that to enter my mind at once.
