If the revolution had never happened, or gone the other way, there would not have been the Lousiana purchase. The British Empire would never buy something from the French, not if they could just take it.

The Royal navy would have a fairly good blockade up, so there would be minimal support available from France. The french speaking colonies would have had had no chance. See Canada and Qubec as an example...


Who knows where the border might have ended up? If the British Empire had been running the Southern border, a process similar to that in Inda might have happened. Support one side in one of their petty arguments, be invited in as traders, or millitary advisers, and quite soon, the Generallisimo of that little state finds the British are running it, and have to secure the border with the next one to stop the bandits. Repeat!
