Not really, A bear without Eyes still has brain functions, a Dragon without a head is just dead.
At least the dragon has a soul. A bear is just a beast, governed by instinct and emotions. One might argue, what good is a head with nothing in it? But that's just courting the same racism Ulfric shows for all he considers pawns in his little white supremacist power grab.
Anyway... People assume that a Stormcloak victory means Skyrim going it alone, but that is never the intent. Ulfric says "Skyrim will lead all of Tamriel..." He does not envision fighting alone. It will be hard to make peace with Cyrodiil after this, but if Hammerfell can do it then so can Skyrim. Cyrodiil needs to stop trying to dominate/ use/ abuse its neighbors and start working with them, as free equals.
Skyrim doesn't have the resources to go it alone. As it is they have to support one another with resources from neighboring townships just to keep the fires burning. Any real conflict, like a full force Dominion incursion, with some well-placed magics to torch the winter stores of food and lumber, and the Nords are routed.
Without supply line support from Cyrodiil, all Ulfric's dreams of uniting Tamriel under the banner of rugged white supremacist determinism is worse than if it were unified under the gold banner of the Thalmor.
The "Spirit" of what they are doing is counter-productive. True, the Empire has made mistakes, but those making them were HUMAN. The SPIRIT of the empire is still the right path. Corrupt as the Roman Empire became, it's collapse only led to chaos which brought about the long centuries of hell we call the "dark ages."
Every man for himself NEVER wins. It is easier to conceive in the sort term, but it is a backwards step for humanity.
