Okay, I will try to better explain my point. I am a foreigner, and what your country associates with in my view - something recognizable, that makes it different from the neighbours, something that has a historic value? The royals and the Victorian era. Having said that, I should admit that I don't care much about your royal buffoons and don't like some things that were common in the times of Victoria. But nevertheless, it is those things that make Britain 'British'.
Without them.. Palaces and old buildings? Germany, France, Austria and Italy have them more than enough. You don't have the seaside (I hope you understand in what context I use that), mountains, cuisine, national 'coloring'. In other words, the things that people look for in other countries they visit. Or okay, you have them, but Britain is a shadow of Europe without some 'original' images.
I hope I cleared up my point a little bit. And no offence meant, of course.
