So claims its leader. One reason why we spend so much time at American Creation discussing the Founding is people value the American Founding. Folks make an argument -- perhaps logically fallacious -- of appeal to the authority of the American Founding. It's like the argument ad populum. It may be logically fallacious, but in a democracy it has some value to it.
Interestingly, there are some conservatives who might agree with Assange's claim. The American Revolution was, after all, a revolution. Revolutions by nature defy prevailing political authorities.
Those conservatives who want to value the Founding but not revolutions, get around that by arguing, perhaps correctly, that the US Constitution, NOT the Declaration of Independence is what governs America.
