Explanation: President Donald Trump announced that the United States had struck a deal with Denmark giving Washington "permanent control over security, and all other needs" in Greenland, months after repeatedly threatening to take the Arctic island by force.

The deal is expected to be signed at the United Nations General Assembly the following week.
