Othrwise the world and history are both littered with the wreckage and corpses of indiviuals and nations who didn't see and understand the need or the tie.
The other essentials are faith in God, morality (those two are tied together) and free will. Those are the true bedrocks to the liberty the founders glimpsed, fought for and tried to vouchsafe IMHO.
