The Stormcloaks here raised a point about the Empire being concerned with Cyrodiil and Cyrodiil only - all fine, but why exactly do you assume Ulfric isn't just going to do the same with Skyrim? At best, Stormcloak victory would result in Talos worship being allowed, deterring the total apocalypse. But assuming they win, throw the Thalmor out and all - what next? The Dominion is not just going to let them be, they want to stamp out Talos worship. With the Empire getting kicked out of Skyrim, they have no reason to go and help Ulfric if Skyrim gets invaded by the Dominion. Well, if the Emperor decides it might be good in the long run, Skyrim would just get reclaimed by the Empire, at least in parts. I tend to dislike the Stormcloaks because they uncomfortably parallel certain XX-century European regime [GODWIN'S LAW WARNING!] - I mean, say what you want about Ulfric being or not being a racist, the Stormcloaks as a whole opress: Argonians Khajits Dunmer and then there is the whole Reach situation. Also, notice the highlighting of the White Gold Concordat as a treason and a lost opportunity to win the war - that (along with the reasons for the opression of Dunmer) echoes the 'backstabbed' rhetoric used in interbellum Germany. On the other hand, most people get a bad impression with the Empire due to Helgen scene - but it may be blamed on the Imperial captain, who got a bit ax crazy. Hadvar on the other hand, is sympathetic to you. First impressions aside, the main problem appears to be the Empire appeasing Thalmor. This is undoubtedly the biggest flaw in their image. Drawing on the pre-WWII parallels, I guess they are trying to deter the next Great War even for its own sake. On the other hand, I did not see Empire actively helping Thalmor beyond their required duties from WGC. At the time of Skyrim, they are trying to manage a lot of things simultaneously and as a result, they cannot afford a hugeass army invading.
