As a flip of this thread, how small could the US have been (barring stuff like breaking up the Thirteen Colonies up at the get go)? What would have filled in North America in lieu of a US that stretches across the continent?
My guess is that it's going to be basically impossible for the US not to try and have its western border be the Mississippi, and even then it's going to be damn hard for them not to try and nab chunks of the Louisiana Territory.
