the war was actually very easy, it's just that we weren't allowed to win. all we needed to do was kill all of the natives and sell the land plots off to the soldiers who were doing that killing. once they finish their tour, they get grants to settle the land. by doing this over 20 years, we could have entirely replaced the natives with our own citizens and had a 51st state in a strategic position that was populated entirely by combat veterans and their family farmsteads. maybe keep some of the natives around as sterilized slave labor until we had sufficient population in the region. it wouldn't have cost us any more money than our timeline either.
