As for the exact reason for the uprising, that is something really only Ulfric knows. If Skyrim had tried to start too fight the thalmor alone, (like the Redguards did) why the empire would probably sell them out to.

Point taken, and I agree. This time, when war is taken to the Dominions land it must stay there until the threat it represents is no more. No matter what making sure of that entails or how long it takes. The peaceful and tolerant way has already been tried, and it failed.
