Die Vereinigten Staaten hätten die Grenzen des Vertrags von Fort Laramie aus dem Jahr 1851 eingehalten

Do one for if all treaties had been upheld

Okay but they would have drawn state borders differently then the. No one is admitting a state shaped like this Nebraska, and the Dakotas would probably be one state.

America nearly had our own Lesotho.

This is an interesting map, but it also fundamentally misrepresents the Fort Laramie treaty.  The treaty would have granted this land to the Lakotah nation in the form of a reservation, not as a state or independent nation.

Reservations exist across the breadth of the United States within existing state borders, and in some cases cross state lines.  The creation of this reservation would not have diminished the size of North or South Dakota, Nebraska, Wyoming or Montana.
