greenland has autonomy. the local native population have legal and political rights. they are related to the canadian inuit in nunavut and the morthwest terrotories, and they are developing a sort of common wealth between the three and accepting alaska natives. the usa doesn't support this. canada and denmark do support the northern group.

major international border issue.
