The struggle over the future of Greenland has moved from a diplomatic disagreement over a specific issue to a wider arena that tests security strategies in the Arctic region, U.S. missile defense plans, and the extent of non-U.S. great powers’ influence. At the heart of it is President Donald Trump’s assertion that control of the island is vital for the country’s security, especially with regard to the Golden Dome missile defense system.
The importance of Greenland for Washington has been based on both geographical and natural resource considerations. The country is located along the Greenland-Iceland-UK Gap, which is a maritime passage of great importance for the observation of traffic in the North Atlantic. In addition, it has the Pituffik Space Base, which has been functional for many decades. The country has deposits of rare earth elements that are found in larger quantities in the world in its subsoil. The melting of the ice in the Arctic region has increased access to these deposits.
Trump has also directly associated Greenland with “Golden Dome,” an intricate missile defense system that will integrate ground-based interceptors, radar, and space-based sensors. The system, announced in 2025, aims to protect against ballistic, cruise, and hypersonic missiles from peer and near-peer competitors. Although the administration contends that American sovereignty over Greenland will improve its ability to deploy troops there, defense experts observe that current agreements with Denmark already allow extensive American military operations in Greenland.
These date from 1951 and have enabled the US to maintain and expand these facilities without any disputes over sovereignty. “It’s like he doesn’t realize that for decades we’ve had a major base in Greenland that is crucial to homeland missile defense and space surveillance,” said Todd Harrison, a defense and space policy expert. Danish researchers also draw attention to the fact that previous US demands based upon their fundamental security requirements have been received favorably.
In addition to missile defense, another area where Greenland’s resources are at the center of a broader struggle for access to critical supply chains is in mineral resources. Greenland is one of the world leaders in rare earth mineral deposits, though it lags in developing these due to its inhospitable climate, lack of infrastructure, and indigenous opposition to projects that pose environmental hazards. However, China’s control over rare earth refining makes such deposits critical, given that China has attempted to invest in Greenland’s mining industry, an act that was thwarted by both Denmark and the U.S. due to security concerns.
The conflict also highlights internal rifts in NATO. Denmark points out that any unilateral U.S. move to seize Greenland will weaken NATO itself, since a common defense pact will fail if a NATO state is fighting one of its allies. NATO members such as Canada, Germany, and the U.K. have expressed solidarity with Denmark in supporting the sovereignty of Greenland, while at the same time emphasizing cooperation on Arctic defense with Denmark. All of these developments are happening at a time when NATO is trying to meet its commitments in Europe while shifting focus to the High North.
Greenlanders have been unnerved by the rhetoric emanating from Washington. The leadership in Greenland asserts that it is up to the people of the island to determine its future and that there is no desire for extensive foreign domination, whether it be by the U.S., China, or other foreign powers. The history of political struggles involving uranium mining suggests that worries about the environment and sovereignty have been more important than economic considerations.
With the melting of Arctic ice and the rising level of strategic rivalries, it can be ensured that Greenland will remain at the crossroads of strategic affairs related to missile defense, mineral security, and allied politics. It will not only be a decisive factor in shaping the destiny of the island but also have a bearing on NATO unity and the future of security policies in the Arctic region.
