State governments are not what they once were. Once they were sovereign entities that had made treaties with an entity called the United States of America.

Somewhere in the last century (the 1900s) the states became subsidiaries of the Federal Government, which also is not the sovereign entity it once was.

As subsidiaries, they CAN'T secede or revolt legally. To do it legally, we have to start from scratch, forming new sovereign entities while forcing the present ones into disuse.
