Trump announces Greenland security agreement and expanded U.S. military access

President Donald Trump has announced what he describes as a permanent agreement giving the U.S. greater control over Greenland's security and allowing a significant expansion of the American military presence on the island.
The announcement could have implications for Arctic security and U.S. strategic positioning in the region.
Further details on the agreement's legal structure, implementation and the positions of Greenland and Denmark will be important for assessing its practical scope.
