The word Sovereignty has been greatly undermined by the feckless left, but you are correct.
What I want to know is who in the heck allowed or agreed to allow Brittain sovereignty over land in our nation? Evidently Washington DC is a terroritory too under their control? We fought a war to secure America as ours and the lovers got to dictate terms?
Sorry meant to say “and the losers get to dictate the terms and keep some of the land?”
Yes, it is American land currently occupied by a foreign power. The DOD Law of War manual goes into this in detail (Chapter 18, I believe).
