And that previous poster must've also missed the fact that seceeded states were no longer bound by that instrument.
The only way to secede is at the point of a gun. It is just another name for revolution, as Madison said.
The rebels never seceded because they couldn't generate enough force to do so.
Look at Tennessee. Nashville was occupied by Union forces only 10 months after the secession ordinance was adopted. So is 10 months long enough to validate secession? Heck, you can do better than that; if the neighbors don't find out you've seceded, maybe the feds won't either.
This "the laws don't apply to us because we don't like 'em" argument is pitiful, as much as anything.
