Brazil Hollandes back to the Netherlands?

Within the quasi one billion people strong new MercEUsul CPLP community, local anomalies are going to need stretching out. Savoy is not in France, neither is Brazil Hollandes in Brazil. Brazil Nordeste was sold by Netherlands Prime Minister to Portugueses, or Jews; (not clear who founded Brazil). International civil law does not seem to tolerate selling a territory and a population without residents consensus. This kind of geopolitical machinations were hiding under the radar, within desorderly local governance. But it would look out of place within the now largest and most powerful community in the world. Lawyers are sharpening their knives.
