Rather poor form that, Wot?
Our Second Founding document used the term "Perpetual."

Of course the United Kingdom was also a government of "Permanent" or "Perpetual" nature, and so the very authority to which we appealed to break it was the laws of nature and of nature's God.
If the laws of nature and of nature's God can break allegiance owed to a thousand year old monarchy, then it is certainly sufficient to break all lesser enduring forms of governance.
And still more nonsense, it never stops with DiogenesLamp.
Our Declaration of Independence refers first to necessity:
The Declaration clearly spells out the necessity, in two dozen items, including:
Nothing remotely resembling such necessity existed after the November 8, 1860 presidential election, and yet Deep South Fire Eaters immediately began organizing to declare unilateral unapproved secession at pleasure.
That's why even the North's most Southern-sympathetic Doughfaces like Democrat President Buchanan did not see Fire Eater secession as constitutionally legitimate.
And slave-holders in Upper South and Border slave-states totally refused to secede, so long as they considered it nothing more than at pleasure.
Virginians did not believe the Constitution had been "perverted to their injury or oppression" and so refused to secede in early 1861, until after Jefferson Davis gave them a war to make secession "necessary".
But even then Border States didn't think secession "necessary" and so still refused.
But brilliant as he is, DiogenesLamp has never figured that out, even when it's pointed out clearly to him.
