I don't agree with this, and neither does the Greenland Home Rule: https://naalakkersuisut.gl/en USA has a base to the very north east of Greenland (Thule Air Base), but most of the workforce there is people from Denmark and Greenland. They used to have other bases (e.g. Sonderstrom), but are currently primarily based on Thule. However, after the POTUS offer on buying Greenland, USA is now (re)opening a consulate there.
