You're absolutely right, Dr. Williams. Not ONE state would have signed the compact of 1789 if they thought they were all signing a sovereignty suicide pact.
Also, the war settled nothing, it only deferred the issue to another time. Next, secession was not declared illegal until the kangaroo Supreme Court of 1869 in White vs Texas.
Finally, unlke dligon, who clearly has no idea what he's talking about, I've actually studied the issue, and the lame things those who justify the unnecessary slaughter and the over a century and a half of malice that followed is mind bending.
Secession, as you say, Dr. Williams, is the honorable and best way out. The USSR allowed it.
