I honestly don't think you can include the Native Americans in an insurgency discussion, at least not in a blanket sense. You could make that argument in certain locations and during specific time frames, but that's about it. The Modoc War, many of the Apache excursions after about 1875, and the Crow Uprising would certainly qualify...but that's under my own interpretation of the Indian Wars (which considers something a possible insurgency after a tribe had been shifted to a reservation).
