Morrowind is the only stable one in the list right now, even then it showed it's worthy of existing by surviving the Fall of the Tribunal, The Oblivion Crisis, the Red Year, and the Argonian invasion and not only did they survive them, they survived them back to back. Meanwhile Skyrim is stuck in a civil war that in the end would be pointless. The Empire is -blam!-ed over thanks to the death of the Septim Dynasty and the Nation of Hammerfell like Skyrim is in civil unrest. Over all I'd say the only stable nations are the Aldmeri Dominion, Argonia, and Morrowind.
