So, there's this theory which says that, with the White-Gold Concordat, the Dominion intended to separate Skyrim and Hammerfell from the Empire (which is why the terms banning the cult of Talos and giving portions of Hammerfell to the dominion were included), and then, consequently, High Rock, as it wouldn't have any Imperial-friendly way to Cyrodiil; then, the Empire would crumble, as it'd be made solely of Cyrodiil. And that makes a lot of sense, actually.
But in the Thalmor Dossier: Ulfric Stormcloak, it is said that a stormcloak victory should be avoided (as an Imperial one). Does that somehow refutes the "empire segregation theory"? If it doesn't, why not?
