Answer 3

STATE. To understand a state, a people permanently occupying a fixed territory bound together by common law habits and custom into one body politic exercising, through the medium of an organized government, independent sovereignty and control over all persons and things within its boundaries, capable of making war and peace and of entering into international relations with other communities of the globe.

NATION. Now, to understand Nations as states being independent bodies politic; societies of men united together for the purpose of promoting their mutual safety and advantage by the joint efforts of their combined strength.
Now, in consideration of international definitions of “state” and “nation” by Black’s and Bouvier’s, respectively, let us add the federal government back into the equation. The constitution for the [U]nited States of America is nothing more than an international agreement between the American republics and their respective nations. Accordingly, in the forming of our federation, each state of the Union gave up some of their inherent rights of statehood that they possessed under general principles of international law. However, one right the states did not give-up is their respective and individual nations. This principle of law is exemplified in the provisions set forth by the Ninth and Tenth Articles in Amendment in the Constitution. Now, understand that NATIVE, a natural-born subject or citizen; a citizen by birth; one who owes his domicile or citizenship to the fact of his birth within the country referred to. Black’s Law Dictionary, Sixth Edition, and referring back to the definition of Nation in the previous "Nations as States", we can come to understand that each of the several 50 states are independent nations, and are independent of the federal government and that the federal government can not be a nation, but is in fact an agent, and only an agent of the Nation States. This is as per the Organic Constitution which has been made somewhat mute as per the "Reconstruction Amendment", the Fourteenth Amendment which in and of itself is an illegal amendment. This is a very sensitive and difficult subject which requires much more time and room than allotted here.
