While I’m not opposed to your point of view here, the United States does predate the Constitution. The United States existed under the Articles of Confederation from the end of the Revolutionary War until ratification of the Constitution, nearly a decade.
Which is, in and of itself, true.
The point I'm trying to make is that neither the Articles nor current compact create the supremacy espoused by those who tend to believe that the Constitution is some kind of suicide pact.
