Pretty much, though I will disagree on some points:
1) Black Marsh doesn't control Morrowind. The Argonians left Morrowind after going on a rampage of slaughter against an already devastated foe. The Dunmer are currently rebuilding their Kingdom on the Island of Solstheim. The Dunmer were never really a fan of the Empire, and seeing as how the Empire didn't help them a bit during their greatest time of need, I can see Morrowind seceding from the Empire formally sometime soon. And frankly, the Empire is much too weak to stop them.
oh, i looked at the lore didnt see anything about the argonians leaving.
2) Hammerfell is its own sovereign Kingdom now. The Empire was going to cede about half of it to the Aldmeri Dominion in the White Gold Concordat, but the Redguard's (for good reason) didn't like this and continued to fight. The Empire told them to lay down their arms or be kicked out of the Empire to fend for themselves (stupid decision by the Empire...), and so Hammerfell effectively gave the Empire the "finger" and seceded from the Empire by continuing to fight. They soundly defeated the Thalmor, and drove them completely out of Hammerfell.
i thought i said that just in a sumarized form.
3) Yes, the Bosmer and the Khajiit are apart of the Aldmeri Dominion, but only about half of Valenwood was taken by the Thalmor. The Kingdom was effectively cut in half with the other half actively resisting the Dominion and the Thalmor at every turn. Elsweyr was forced into the Dominion by the Great Mane being assassinated and thus lack of leadership, but the Khajiit are very wily and crafty. It wouldn't surprise me at all if the Khajiit were just playing along until the opportunity came around to seriously [censored] over the Thalmor.
like i said they were forced into the dominion and hate them for it.
The Thalmor are doomed by their own actions, and they've spread themselves much too thin to be able to defend the territory that they have captured. They've taken far too many losses in their small, small victory over the Empire, and just like the majority of the German populace weren't Nazi's in WWII, the majority of the populace of the Dominion are not members of the Thalmor.
i know that. the thalmor are not high elves in general they are the goverment.
It's only a matter of time before the Thalmor are destroyed by their own ambitions.
indeed.
