Tiber Septim united all of Tamriel under one banner, for that he was ascended to god-hood. Praying at his shrine does grant you a buff and cure your diseases, so its safe to assume that he really is a Divine now.

And to answer your question, In my fair opinion, the thalmor are wrong.

Reason as to why, is because the Aldmeri Dominion claims they have ended the oblivion crisis, when we all know it was the Champion of Cyrodiil who did that. Moreover the empire has aided the summerset isles quite a few times before, including when the Maomer tried to raid the summerset islands free of any elves there, but they were driven off because of the Imperial Navy. Now as soon as The Empire was left weak without an emperor and the damage the oblivion crisis has caused, they just retreated from the empire and declared war on them taking advantage of the sittuation.
