The U.K. and the old U.S.S.R. didn’t meet the definition of “nation-state” but were considered “countries.”
And according to Wikipedia, the “Kingdom of the Netherlands [is not a nation-state but] consists of four countries.”
Speaking of Wikipedia, this clarification might be helpful:
I don’t think I’ve ever heard either of these referred to as countries. Lifelong USAian here. “Islands,” yes; “possessions,” I think so. But “countries,” I don’t believe so. I certainly wouldn’t call them that.
As others have said. In the US it really is very simple: country DOES equal nation-state.
You know, for all this page-long hijack about what is/isn’t country, can’t help but notice that nobody’s objected to my description of Glasgow, Scotland as “dreary”.
Well, it’s not a capital, jackass. Glasgow does indeed have its dreary elements, but I find it beautiful in its own way. One of my friends has a heart-felt photo documentation of the city called “Disappearing Glasgow”. Wonderful photos and chronicle of a changing city. Perhaps this has to do with my fondness for the place.
