Thank you for posting the esteemed President Washington to make my point.
Notice he says our 'national capacity' is American.
That's because American is our nation, and the United States is the government created to smooth relations between the several States.

"The federal government, then, appears to be the organ through which the united republics communicate with foreign nations, and with each other. Their submission to its operation is voluntary: its councils, its sovereignty is an emanation from theirs, not a flame by which they have been consumed, nor a vortex in which they are swallowed up. Each is still a perfect state, still sovereign, still independent, and still capable, should the occasion require, to resume the exercise of its functions, as such, in the most unlimited extent.

He also said that our loyalty to our country as citizens of the United States should override any regional loyalties such as those to state or locality. You suggest just the opposite.
