If anyone is looking for the legal perspective, I believe the Supreme Court's "Texas v White" is the pivotal case. From Wikipedia [1] : >> In deciding the merits of the bond issue, the court further held that the Constitution did not permit states to unilaterally secede from the United States, and that the ordinances of secession, and all the acts of the legislatures within seceding states intended to give effect to such ordinances, were "absolutely null".
