Existing indigenous nations govern the land. Even the neo-Colonial IRA governments are at the forefront of fighting climate change, habitat destruction, and mass extinctions (almost all biodiversity is on indigenous managed land). There are Communists in these nations trying to build them into radical socialist projects. Some nations are very radical.

The settlers will be governed by a joint dictatorship of the oppressed nations, but will have political rights within revolutionary institutions for women, LGBTQ2S+, youth, workers, etc. Much the same as how the CPC rules China, the dictatorship will be selective in who it elevates into the state machine but will stay in touch with the masses through mass organizations like those listed above.
