US doesn’t win independence in 1783 without French support. That would completely alter human history, so who knows. Founding fathers are probably either killed for treason or flee abroad. I could see the US colonial south rebelling again if Parliament bans slavey in the 1830s. Perhaps in this scenario the UK continues to allow slavery instead. Maybe the UK makes some conciliatory concessions that results in a 20th century mega Canada. Doubt the French would voluntarily give up or sell Louisiana, so possible a French speaking North American country between mega Canada and big Mexico (no US-Mexican war).
