That books keeps coming up, and people keep saying it proves the Ulfric is working with the Thalmor, but that's the opposite of what it says. The book is the Thalmor Dossier on Ulfric Stormcloak, and it's potential spoiler for those who have not done Diplomatic Immunity. What it actually says is that the Thalmor were actively manipulating the guy into doing his bidding until the Markarth Incident, at which point Ulfric realize he was being played and basically told the Thalmor to go screw themselves. It is explicit that he will not co-operate with the Thalmor, accept their aid in any form, or even deign to talk to them. He's not working with the Thalmor, he's trying to work against them. Unfortunately for him the Thalmor are clever and have manage to turn even his attempts to spit in their eye to their own advantage, but that's just how they operate. They are also playing the Empire to their own advantage as well. Think about it, if the Empire's response to the Stormcloak Rebellion had been to let the Nords figure it out themselves, then there would have been no war. The moot would have been called, a new High King elected, and that would have been that. By fighting, they are playing into the Thalmor hands as much as Ulfric is. The most important part of the document is that it proves that the Thalmor do not want the Stormcloaks to win. What the Thalmor want is a long drawn out war with no conclusion.The want year after year of pointless bloodshed. It proves that there is no right side or wrong side for the player to pick. A quick end to the war spoils the Thalmor plans either way. It doesn't matter if it's the Stormcloaks or the Empire who win, just so long as someone does. The only real wrong choice is to not make a choice at all. So pick which ever side you like best and help them win, it's cool either way.
