Denmark, Greenland and the United States are expected to finalise a landmark Arctic security agreement at the UN General Assembly in New York on Tuesday, with Danish Foreign Minister Lars Lokke Rasmussen confirming that NATO will share responsibility for the Arctic rather than leaving it solely to Washington and Copenhagen. Trump has declared the deal gives the US "permanent control" over Greenland's security, while Denmark and Greenland say it will respect the island's sovereignty and benefit all three parties. Greenland's Premier Jens-Frederik Nielsen welcomed the agreement, saying it would "ensure and strengthen" security on the island.
Under the deal, no US adversary can maintain a military base in Greenland or make sensitive investments there without Washington's written approval.
The agreement follows months of Trump's threats — including refusing to rule out military or economic force — which triggered a diplomatic crisis within NATO.
US Ambassador to Belgium Bill White told Euronews the standoff is over: 'It's been resolved.'
