....And as for "The Elder Council is in the pocket of the Thalmor! See here in this book that predates the Great War!"
First off... as I stated in the paraphrase, it's predating the Great War by quite a bit. Since then, the Dominion Army has burned the Colovian countryside and r(sixual violation)ed the Imperial City itself. The Dominion made it quite clear their intent by that time. Any Imperial-aligned politician that deals with the Thalmor is either trying to make the best out of a [SEHT]ty situation or is an idiot like Jarl Siddgeir, and probably isn't popular with the people thanks to their dealings.
The Imperial Legion itself is stocked with politician-disliking top brass that are still sore over the previous Great War. Like General Tullius, Legates Rikke and Fasendil. I doubt they'd follow the command of toady Councilors if the [SEHT] looked ready to hit the fan.
