And so the case is about more than pipelines....
and not about casinoes either... 
mentioning the Doctrine of Discovery here, is to bring attention to a root injustice that's been built upon as you so accurately say it is foundational to grasp the legal origins of the US.  So, is it possible for that knot to get untangled? not all at once of course but bit by bit, voluntarily - like move the pipeline to a non-threatening route.  The call to prayer is moving the case to a plea for mercy. Remember the Cubs just won the world series, so, I'd say the odds are in the favor of mercy coming in whatever way God proclaims.  A window of opportunity?
