A better example would have been: "England" and India were never 'the same country' despite the British control of India.
I will concede that I tend to agree with you on that one.
Wales, on the other hand, very clearly was 'legally' annexed by England, but culturally maintains a very clear sense of itself as a separate people, some would even say a conquered nation.
Some would say that the American south was conquered by
northern aggressors, and there are significant cultural differences
between the north and the south. This is neither here nor there,
the way I see things.
We have one government, free movement, extensive intermarriage, ...
we are functionally one country. The rest of the world certainly
can't be expected to see these nuances; to them we're *all*
Yanks, even those who are actually from Georgia.
It was not my intention to offend the English. (Umm. Or the
Welsh, or the Scotch or Irish.) But from the other side of the
ocean you look very much like one country (excepting the Republic
of Ireland, and I don't care to discuss the question of Sealand).
And I'm not clear on exactly why that should be offensive.
On the other hand, China and Taiwan look very much like two
countries (albeit with some cultural things in common),
and I'm still trying to figure out why that's offensive to them.
