New York Times: “For Mr. Trump, it was a major retreat. He first raised the possibility of buying Greenland during his first term, and never let go of the idea. Even before he was inaugurated, he was making a national security case for making the territory part of the United States, acutely aware that, if he could get it, it would be an acquisition on the scale of President Thomas Jefferson’s Louisiana Purchase.”“And few issues did more to galvanize European allies against the Trump administration, especially once they feared that he might make a military move against a NATO ally. There is no evidence he ever seriously considered that step. But that did nothing to alleviate the fears.”
