Not at all the hairsplitting and arguments over legal form of the Union is all on your side. It was a Union which existed even though all the states did not ratify the Articles until 1781 when the War was almost over. The "Peace" which followed was not ratified for another two years but was no less real than the Union which had won it in spite of incomplete paperwork.
Yeah, "not everyone was in the Union, but everyone was in the Union because I said so".
Listen to yourself.
And wipe that little bit of drool off your chin.
The "Peace" which followed was formalized in the form of a treaty between Great Britain and thirteen independent states.
His Brittanic Majesty acknowledges the said United States, viz., New Hampshire, Massachusetts Bay, Rhode Island and Providence Plantations, Connecticut, New York, New Jersey, Pennsylvania, Maryland, Virginia, North Carolina, South Carolina and Georgia, to be free sovereign and independent states, that he treats with them as such, and for himself, his heirs, and successors, relinquishes all claims to the government, propriety, and territorial rights of the same and every part thereof.
