I don't know about Bolivia, but it seems like what they did in Nicaragua according to that video you posted can't be what American progressives mean when they say land back though, since America already has autonomous regions for Indians just like Nicaragua. That's not even bringing up the fact that Miskito are a former British colony, are closer to Anglos and have a different culture from the Nicaraguans, meaning they need different schools that teach in English instead of Spanish and all sorts of other differentiated infrastructure that American Indians don't i.e. there's a different possible interpretation of "autonomous" more akin to China's autonomous regions.
