Trump’s Greenland Deal Revives Old Tensions With Denmark
Greenland is part of the Danish kingdom, but it is also very important for American defense.
The United States has used Greenland for military purposes since the early Cold War.
A new agreement reportedly gives America continued access to bases, airspace and military construction.
However, many of these rights were already granted by a treaty signed in 1951.
Greenland is becoming more important because the Arctic ice is melting and new shipping routes may open.
Its natural resources may also become easier to reach.
The article says countries used careful negotiations to protect their alliance during the Cold War.
It argues that President Donald Trump’s public pressure could hurt the trust that made those agreements possible.
The new Greenland agreement reportedly gives the United States permanent access, basing and overflight rights.
Officials say the agreement may allow the United States to build additional military structures unilaterally.
The article argues that many reported American privileges already existed under the 1951 Defence of Greenland Treaty.
Greenland’s strategic importance is growing because of melting ice, Arctic shipping routes and potential mineral access.
The article says Trump’s confrontational approach risks damaging decades of trust between the United States and Denmark.

Strategic Necessity
Diplomatic Risk
Value of the agreement
Strategic Necessity
Supporters can view expanded American access as useful for addressing security concerns and preventing China or Russia from gaining a strategic foothold in Greenland.
Diplomatic Risk
The article argues that many of the reported rights were already secured by the 1951 treaty, making the new agreement less substantive than claimed.
Approach to Denmark
Strategic Necessity
A forceful American approach may be seen as a way to secure control over an increasingly important Arctic region.
Diplomatic Risk
The article says public pressure and bullying could damage the trust that has sustained United States-Denmark cooperation for generations.
Military presence and nuclear weapons
Strategic Necessity
American bases and nuclear strategy were presented during the Cold War as necessary to deter the Soviet Union and defend NATO allies.
Diplomatic Risk
Denmark and Norway feared that hosting nuclear weapons could make their territories targets, while Greenland later became a nuclear-free zone after the Thule crash.
- Reported agreement
- Officials said it provides permanent access, basing and overflight rights for the United States.
- Military construction
- The agreement is reported to give the United States unilateral power to build additional military structures.
- Earlier treaty
- The Defence of Greenland Treaty of 1951 already granted the United States control of airspace and anchorage over designated defense areas.
- Cold War facility
- A secret ice facility built in northern Greenland in 1959 was intended to expand into a large military complex.
- Facility closure
- The ice facility was abandoned within two decades after shifting ice crushed its tunnels.
- Nuclear policy
- After the 1968 Thule crash, the United States agreed to demands for Greenland to become a nuclear-free zone.
- Strategic change
- The article says Arctic routes may become ice-free year-round before the middle of this century.
