Native alliances in an alternate War of 1812

Could British retention of the northern colonies lead to a Native American protectorate instead of the historical pattern of American expansion?

The panel considers British support possible within the scenario, which would also leave the United States with fewer resources and a more heavily populated British frontier to cross.

The follow-up begins with the Native coalition that fought alongside Britain around Ohio and Michigan. It asks whether continued conflict with a smaller United States could create room for a British-supported Native American protectorate. British support is treated as possible within the scenario. Losing New York and Pennsylvania would also deprive the United States of resources available in the historical War of 1812. An American advance would face a more populated British-held region with probable garrisons, changing the military conditions under which such an arrangement might develop.
