I’m going to rewrite your note and substitute the definition of nation that YOU provided. Since the American nation doesn’t exist, the term nothing will be used as a substitute, There is the "nothing" the nation (comprised of the _actual_ American people), and nothing the country (the territory) that the nothing nation occupies, along with several other nations and diasporas. This note is complete nonsense based on your definitions of a nation.

The American nation does exist. It is a distinct people (not to be confused with a country, or a nation-state, etc etc), as I have been patiently trying to explain for over a dozen posts. If you're unable to parse the concept because of some prior miseducation or an unacknowledged conflict with your worldview, sorry but can't help you there.
