Dissolve the union

no "legal" moves need to be taken to dissolve the U.S.A. It is already an entity that has no legal authority. In this case, the Union does not legally exist.

I endorse dissolving the U.S.A. This does not mean that I endorse the 50 states or whatever political combinations of states result as a final ideal political system. I simply view that outcome, which ends the national (usually called the federal) government as greatly preferable to what we now have. Individual states could profitably break up too, but that is another matter.
