"Countries" or "Regions" 

From American Heritage Dictionary of the English Language for "country":  "1. a. A nation or state. b. The territory of a nation or state; land. c. The people of a nation or state; populace... 2. The land of a person's birth or citizenship..."  And "nation":  "1. A relatively large group of people organized under a single, usually independent government; a country.  2.  The government of a sovereign state."  Thus the word "country" in American English at least is bound up in the notion of sovereignty.  The use of "country" in this title by a single editor is a legal artifact of the wording used to bind Scotland, Wales, etc. to the United Kingdom.  It is not a term in general use for administrative divisions, but a term of sovereignty for the majority of English speakers as evidenced by the dictionary definitions of "country" and "nation".  There is no insult intended for Scotland et al. by referring to them as Regions.  Actually, I think that "Administrative Division" might be an even more accurate term for this section since non-administrative divisions are covered later. (  )
