camberiu as usual has managed to sabotage a thread and made it into something about Brazil or is this RioExPats forum now?
I think, frankly, that this thread has strayed quite far from my original question. For those of you who know a lot about the history of the Rio de la Plata (esp. in the early 1800s, like with the 1806-07 British invasions), my real question is: Would a British Uruguay alongside an independent Argentina (north of Patagonia) with even more British influence than in real life (possibly a British Patagonia added) have been more realistic, given the circumstances surrounding the 1806-07 invasions and their aftermath, than the whole of Argentina (plus Uruguay) becoming British over the long term?
