One important difference:

Grant and Lee, at Appomatox, crafted a surrender that sent Lee's troops home. There were a number of Lee's staff who wanted them to stage an endless guerilla war from the mountains. Without that dignified adherence to a surrender document, the temporary bitterness of the Reconstruction would have become an entrenched divisiveness rivaling Ireland or Israel/Palestine.

Obviously, no equivalent for that exists in Iraq.
