European troops arrive in Greenland as talks with US highlight 'disagreement - World News
Troops from several European countries continued to arrive in Greenland on Thursday in a show of support for Denmark as talks among representatives of Denmark, Greenland and the U.S. highlighted “fundamental disagreement” over the future of the Arctic island.
The agreement with US and Denmark back in old times means US gets military supremacy, meaning they can build all the military bases they want to ensure US security, but Denmark/Greenland retains civil control.
Which effectively means US can not do anything but build bases, have jets, and soldiers on Greenland.
