I am no expert, but it seems reasonable to assume that the several States who have agreed to be “United States”, if one or more decides they no longer want to be “united”, that ALL states would then dissolve the *current* union. After which, several different states could *reunite* and form a NEW United States. Theoretically, instead of civil war, the United States could have effectively split into 2 or more “countries”, or the states could have remained separate.
Agreed.
That would be in keeping with Founders' Original Intent.
