President Donald Trump on Wednesday scrapped the tariffs that he threatened to impose on eight European nations to press for U.S. control over Greenland, pulling a dramatic reversal shortly after insisting he wanted to get the island “including right, title, and ownership.”

Axar.az, citing AP, reports that in a post on his social media site, Trump said he had agreed with the head of NATO on a “framework of a future deal” on Arctic security, potentially defusing tension that had far-reaching geopolitical implications.

He said “additional discussions” on Greenland were being held concerning the Golden Dome missile defense program, a multilayered, $175 billion system that for the first time will put U.S. weapons in space.

Trump offered few details, saying they were still being worked out. But one idea NATO members have discussed as part of a compromise with Trump was that Denmark and the alliance would work with the U.S. to build more U.S. military bases on Greenland.

That’s according to a European official familiar with the matter but not authorized to comment publicly. The official, who spoke on condition of anonymity, said it was not immediately clear if that idea was included in the framework Trump announced.
