Why is President Trump’s interest in Greenland a potential threat to NATO?
Why is President Donald Trump’s interest in Greenland a potential threat to NATO?
As President Donald Trump continues to insist that the United States maintain control of Greenland, federal officials are quietly preparing to spend tens of millions of dollars in renovations to the only U.S. military base on the frigid Arctic island.
Among the upgrades planned by U.S. military officials are a number of facility upgrades, including renovating Pitafik Space Station’s two-mile-long runway, new boats to keep the harbor free of icebergs, and repairs to the Dundas dining facility. Currently, about 150 U.S. military personnel are stationed at the former Cold War-era Thule Air Base, along with hundreds of service members and contractors from Canada, Denmark and Greenland.
The base (pronounced be-duh-fiek) was renamed in 2023 under the Biden administration to honor Greenland’s indigenous peoples and culture. It is home to the northernmost deep-water port controlled by the Department of the Army (officially known as the Department of Defense), and President Trump believes control of the entire island is key to U.S. security.
“America needs Greenland,” President Trump said in a social media post on January 14.
Because of its location between Moscow and Washington, Cold War military planners built bases there with Danish permission. Greenland is an autonomous country that is part of the Kingdom of Denmark, which itself is a member of NATO and therefore an ally of the United States.
Few details of the exact work at Pitafik Station have been made public, but the improvements come at a time of intense focus on the glacier-covered island, where temperatures routinely drop to -50 degrees Celsius during the polar darkness, which lasts more than three months a year. The base is located on the western tip of the island, near Canada’s Baffin Bay region and approximately 1,000 miles from the island’s capital, Nuuk.
None of the base improvements reviewed by USA TODAY through the federal purchasing system appear to suggest a significant increase in size or change in mission. For example, runway renovations include improvements to the landing and taxiway lighting systems. This is a critical component given that the facility remains in darkness for long periods of time and relies heavily on resupply flights from the continental United States.
But notes in the contract documents also mention sensitive work that could be done by the U.S. military or specialized contractors.
Some of the projects have not yet been officially awarded to contractors. Part of the reason is the logistics of getting materials and personnel to the base during the short summer construction period. The contract calls for the use of engineers and other experts licensed in Denmark.
The darkness of winter can be very oppressive for some people, so the base uses “happy lamps” to mimic the sun and prevent seasonal affective disorder. In the summer, the sun doesn’t set for nearly four months, so base personnel cover windows with blackout shades.
U.S. military officials did not respond to requests for comment on the project.
Pitufik’s current stated mission is to host military personnel who coordinate satellite communications and monitor ballistic missile launches, while also monitoring near-Earth space. Base officials have previously said their system can detect a piece of metal the size of a softball from 3,000 miles away.
During the Cold War, military planners used Pitufik as a testing site for Project Iceworm, secretly burying nuclear missile silos beneath the Greenland ice sheet. The effort was halted after scientists discovered that the ice sheet was moving faster than expected.
President Trump and some military experts argue that Greenland will play an increasing role in national security as Russia and China step up exploration and patrols of the Arctic region. Climate change has weakened the sea ice that normally surrounds Greenland in the winter, allowing more ships to take the Northwest Passage from Europe to Asia via Alaska and the Bering Sea.
Additionally, Greenland is home to deposits of rare earth minerals used to make smartphones, MRI machines, and high-tech weapons systems.
The facility is jointly staffed by the U.S. and Danish militaries, and the Trump administration fired the base commander last April over comments he made to employees and contractors after Vice President J.D. Vance’s controversial visit to Greenland. White House officials have indicated they feel the message of solidarity sent by base commanders to international workers undermines President Trump’s position.
