R.E.N. Spells Ren

All the arguing about Sansa aside, the North as a whole has a decision to make. Cersei told Baelish he would be the Warden of the North if he takes care of the Boltons but does that mean the North accepts him? We know Bear Island won't, so are they in open rebellion again against the crown?
Does the North as a whole pledge fealty to Sansa and/or Jon now?
Do the Starks punish the Umbers & Karstarks now?
And that's before talking about the threat coming from north of the Wall.
Littlefinger doesn't want to be warden of the North, his sights are higher than that. With Cersei's power dwindling every day, I highly doubt that's the rung he'll choose to climb. He'll just want an allegiance with the Warden of the North
