Not really...
Rikke: "I'm telling you, Ulfric's planning an attack on Whiterun."
Tullius: "He'd be insane to try. He doesn't have the men."
Rikke: "That's not what my scouts report, sir. Every day more join his cause. Riften, Dawnstar, and Winterhold support him."
Tullius: "It's not a cause. It's a rebellion."
Rikke: "Call it whatever you like, General. The man's going to try to take Whiterun."
Tullius: "Jarl Balgruuf..."
Rikke: "Balgruuf refuses the Legion's right to garrison troops in his city. On the other hand, he also refuses to acknowledge Ulfric's claim."
Tullius: "Well, if he wants to stand outside the protection of the Empire, fine. Let Ulfric pillage his city."
Rikke: "General."
Tullius: "You people and your damn Jarls."
Rikke: "Sir? You can't force a Nord to accept help he hasn't asked for."
Tullius: "If Ulfric's making a move for Whiterun, then we need to be there to stop him. Draft another letter with the usual platitudes, but this time share some of your intelligence regarding Ulfric's plans. Embellish if you have to. We'll let it seem like it's his idea."
Rikke: "Yes, sir."
Tullius: "You Nords and your bloody sense of honor."
Rikke: "Sir."
The Stormcloak sympathizing Jarls such as Laila Law-Giver of Riften and Dengeir of Stuhn of Falkreath (replacement Jarl) doesn't have nice words to say to Ulfric, but they support him because they can reason with him. They probably do not totally support with what Ulfric is doing, but firmly believe that it is Nords that should rule Skyrim, not a weaken down Empire.
Oh and as an extra bonus I just LOVED the way Tullius was OK with Ulfric raiding his city when he said: "Well, if he wants to stand outside the protection of the Empire, fine. Let Ulfric pillage his city. but then quickly came back with this: "If Ulfric's making a move for Whiterun, then we need to be there to stop him." Sounds like Tullius is a flip flopper if you ask me.
