canada could also make use of the louisiana territory and, given that it was initially french-speaking, there's a strong argument that it should be ours in the first place. this would annex most of the mississippi basin and rebuild the old trade routes south from detroit, through saint-louis and nouveau orleans, who should subsequently be renamed to their francophone titles.
annexing nouveau orleans would give canada significant refinery capacity, which it should immediately dismantle in order to meet our climate targets.
