Please note, @stan, @onceuponatime, and @michaelx ...
May I very respectfully suggest an alternate term? A term other than "international," which unfortunately may suffer from some degree of ambiguity?
How about "extra-national," or perhaps "extra-territorial?"
I would like it to be explicitly clear, and well defined semantically and legally, that these extra-territorial jurisdictions (e.g. outer space and "international" waters) are unequivocally NOT under the purview of ANY self-styled nation OR ANY self-styled "united" nations or group(s) of nations, which the word "international" might by some arguments be coerced to describe.
Good point
