ABOARD AIR FORCE ONE (AFP) — President Trump said Sunday controlling the mineral-rich Danish territory of Greenland is crucial for United States national security given increased Russian and Chinese military activity in the Arctic.

“If we don’t take Greenland, Russia or China will, and I’m not letting that happen,” Trump told reporters aboard Air Force One, despite neither country laying claim to the vast island.

Trump said he would be open to making a deal with the Danish self-governing territory “but one way or the other, we’re going to have Greenland.”
