1. You are using the date that the last state ratified the Constitution to make your point. What I stated was that Congress certified ratification on a different date, per Wikipedia. That, of course, may be incorrect, but you didn't prove that because you cited the date for a different activity.
2. You can't criticize my source, correct my information, and then not supply a source yourself.
3. Am I missing something? You excerpt doesn't refute my points but, rather, buttresses them by stating that the states not ratifying were foreign states to one another; that is, independent and sovereign, as I said. It does not say they were still a union with one another; quite the opposite. That's my point, they defaulted to independent states.

A Contract establishes a relationship between the parties. The Constitution is that contract and is the instrument of law that binds the states. Without it, there is no Union. At least in theory, unless you are Abraham Lincoln or any other Nationalist of a like mind.
