(AP) — President Donald Trump insisted he wants to “get Greenland, including right, title and ownership,” but he said he wouldn’t employ force to achieve that — using his speech Wednesday at the World Economic Forum to repeatedly deride European allies and vow that NATO shouldn’t stand in the way of U.S. expansionism.

He urged NATO to allow the U.S. to take Greenland from Denmark and added an extraordinary warning, saying alliance members can say yes, “and we’ll be very appreciative. Or you can say, ‘No,’ and we will remember.”

“This enormous unsecured island is actually part of North America,” Trump said. “That’s our territory.”

Trump also said that the U.S. is booming but Europe is “not heading in the right direction.” His ambitions to wrest control of Greenland from NATO ally Denmark threaten to tear apart relations with many of Washington’s closest allies.
