Personally I think that ideally there should be a coalition of the different provinces and have them all be independent to a great degree. With no province having more influence than the other.

Currently however, the main issue is the issue of the Thalmor. Disregarding the issue of whether Talos is truly an Aedra or not, it is still wrong to deny someone's autonomy by denying that person their choice to religion.

More so their ideology that the high elves are the closest relation to the Ehlnofey is both incorrect and dangerous.

Ideally the oppressive Thalmor government should be overthrown and let the high elves be free to govern again.

From their a collation could be formed of the different provinces to try to prevent further conflict, sort of like the league of nations or the UN but this time it would ideally work.
