President Donald Trump’s yearslong threats to take over Greenland have crescendoed this week. On Wednesday, White House press secretary Karoline Leavitt said Trump is considering a range of options in pursuit of the country, and that “utilising the U.S. military is always an option at the commander-in-chief’s disposal.”
“This agreement is very generous, it’s very open,” Mikkel Runge Olesen, a senior researcher at the Danish Institute for International Studies in Copenhagen, told Fortune. “The U.S. would be able to achieve almost any security goal that you can imagine under that agreement.”
Given the wide-reaching terms of the contract, “there is very little understanding as to why the U.S. would need to take over Greenland at this time,” Olesen added.
For more than 80 years, the U.S. has had a presence on Greenland, which became a foundational part of its deepening relationship with Denmark—and the North Atlantic Treaty Organization (NATO). During WWII, Danish ambassador to the U.S. Henrik Kauffmann, defied the Nazi-controlled Danish government and essentially brokered a deal with the U.S. to give America access to Greenland. A U.S. military holding there would prevent Nazi forces from using the island as a bridge between Europe and North America.
The deal that was supposed to dissolve after the war was instead bolstered by the creation of NATO in 1949, which obligated the U.S. to provide defense for Europe against Soviet forces. A new agreement in 1951 confirmed the U.S.’ rights to establish defense areas in Greenland, and is contingent upon the continued existence of NATO to be valid. In 2004, the agreement was updated to add Greenland, which established some self-governance in 1979, as a signatory.
The U.S. has only one military base on Greenland today, the Pituffik Space Base, down from about 50 during the height of the Cold War. But should the U.S. want to expand its presence there for national security reasons, as Trump has suggested, it would require negotiations with Denmark and Greenland, Olesen said. Historically, those negotiations have been friendly.
“In practical terms, there has been a tendency on the Danish and the Greenlandic side to always look at us security requests in Greenland with a lot of goodwill and a lot of openness,” he said.
Danish Prime Minister Frederiksen, citing the 1951 agreement, implored the Trump administration to stop his talk of taking over Greenland.
In the case of Greenland, Trump could be wanting to send a message to Denmark the U.S. has greater military capabilities that it is willing to deploy.
“Trump believes—and is often very keen to emphasize—the United States as leverage,” Martin told Fortune. “And it’s possible he’s trying to tell Denmark, ‘Look, you are in a position of weakness. Greenland really fundamentally depends on us. Why should we have to avail ourselves of those formalities when really we’re the key player?’”
“If you’re going to go to Greenland for its minerals, you’re talking billions upon billions upon billions of dollars and extremely long time before anything ever comes of it,” he said.
According to Olesen, Trump’s desire for rare earths, as well as his national security urgency, can be addressed by Danish and Greenlandic officials through negotiations, making them less of a concern. The trouble will be if Trump’s biggest motivator to move into Greenland is a symbolic show of military prowess rather than specific demands that can be addressed through diplomacy.
“It’s hard to compromise with territorial expansion,” Olesen said.
