A Newsweek map reveals the locations of two new U.S. military bases slated for construction in Greenland. President Donald Trump recently announced a security agreement concerning the semi-autonomous Arctic territory, part of the kingdom of Denmark. This development comes in the wake of months where Trump threatened to seize the island, igniting tension within NATO, a coalition including Denmark as a founding member.
Denmark, Greenland, and the United States are set to sign the security agreement touted by Trump at the United Nations General Assembly. Reuters disclosed that these bases would contribute to an expanded American military presence on the island, incorporating a previously deactivated Cold War-era installation. Newsweek has reached out to both the White House and Denmark’s foreign ministry for comments.
Where Will the New US Bases Be?
Trump underscored Greenland’s strategic value, stating NATO has enhanced its focus on safeguarding the Arctic amid fears of Russian maneuvers in the region. During the Cold War, Greenland hosted 17 U.S. military establishments with 10,000 staff. Today, Pituffik Space Base remains as the sole installation, employing around 650 personnel, including 200 active-duty U.S. military members.
Reports from Reuters indicate the new bases will be established in Narsarsuaq, located at the island’s southern tip, once home to the Bluie West One base operational between 1942 and 1958. Its peak saw 4,000 personnel, facilitating 10,000 aircraft heading to World War II theaters in Europe and North Africa. The base was abandoned following advancements in mid-air refueling and the Thule Air Base inauguration in northern Greenland.
The second site, Mestersvig, serves as a military outpost in eastern Greenland utilized by the Sirius Dog Sled Patrol, a specialized Danish unit.
What Is Trump’s Deal With Greenland?
Copenhagen has cautiously welcomed the agreement announced by Trump, indicating NATO’s overseeing of Arctic security beyond the U.S. and Denmark’s direct involvement. Although specifics remain undisclosed, a U.S. State Department statement to Newsweek described it as an “unprecedented agreement” ensuring U.S. security interests in the Arctic without financial burden on U.S. taxpayers.
The deal establishes permanent U.S. security control over Greenland, incorporating it into North America’s strategic defense region. Previously, other nations could have been authorized to establish bases or station troops there. The agreement bars such activities from nations like China and Russia. Additionally, it stipulates that Greenland cannot foster foreign investment in sensitive sectors.
Jeppe Kofod from the Atlantic Council noted the U.S. bolsters its enduring security stance in Greenland under the deal, while safeguarding the sovereignty and territorial autonomy of the kingdom and Greenland’s self-determination rights.
