Golden Dome
Greenland’s strategic role in nuclear defense comes into focus amid Trump’s ‘Golden Dome’ push
Greenland’s location in the Arctic places it at the heart of global nuclear defense planning, a reality highlighted anew by U.S. President Donald Trump’s renewed push for his proposed “Golden Dome” missile defense system.
In any hypothetical nuclear conflict involving the United States, Russia and China, intercontinental ballistic missiles would likely travel along the shortest routes, over the Arctic. That trajectory makes Greenland a critical point for early detection and potential interception.
Trump has argued that U.S. ownership of Greenland is essential for the success of the multibillion-dollar “Golden Dome,” a layered missile defense system he claims will be operational before 2029. He has said modern offensive and defensive weapons systems make control of the territory especially important, sparking alarm in Denmark and among Greenlanders.
A key element of Greenland’s importance is the Pituffik Space Base, formerly known as Thule Air Base. Located above the Arctic Circle, the base hosts a powerful early-warning radar capable of detecting and tracking ballistic missile launches from thousands of kilometers away, including missiles fired from Russia or China toward the United States.
Defense analysts note that the base gives Washington valuable extra minutes to assess and respond to potential attacks. The radar can monitor large swaths of the Arctic and detect objects as small as a car, according to the U.S. Air Force.
However, experts question Trump’s claim that U.S. ownership of Greenland is necessary. The United States has operated at Pituffik for decades under a 1951 defense agreement with Denmark, without sovereignty over the island. Analysts also point out that other allied locations, such as early-warning radar sites in the United Kingdom, play similar roles without any U.S. ownership claims.
Some experts argue that emerging space-based sensors planned under the “Golden Dome” could eventually reduce Greenland’s strategic importance. They also note that Denmark has historically been a highly cooperative U.S. ally, making expanded military access possible without drastic political steps.
As debates continue, Greenland remains a pivotal, and sensitive, crossroads in global nuclear defense calculations.

Canada is talking to US about joining ‘Golden Dome’ missile defense system: Carney
Canadian Prime Minister Mark Carney said Wednesday his government is talking to the U.S. about joining President Donald Trump's future Golden Dome missile defense program.
The multilayered, $175 billion system would for the first time put U.S. weapons in space. Trump said the previous day he expected the system to be fully operational by the end of his term in 2029.

"Is it a good idea for Canada? Yes, it is a good to have protections in place for Canadians," Carney said.
Carney confirmed he's had talks with Trump about it and said there are discussions with senior officials. Trump said the Canadian government had contacted his administration indicating it wants to join the program and that he will work with Ottawa to ensure it contributes its “fair share.”
Golden Dome is envisioned to include ground- and space-based capabilities to detect and stop missiles at all four major stages of a potential attack: detecting and destroying them before a launch, intercepting them in their earliest stage of flight, stopping them midcourse in the air, or halting them in the final minutes as they descend toward a target.
“It’s something that we are looking at and something that has been discussed at a high level." Carney said. “But not I’m not sure one negotiates on this. These are military decisions that have been taken in that context, and we will evaluate it accordingly.”
Carney warned that Canada faces potential missiles threats in the “not-too-distant future” that could come from space.

“Is Canada going to be doing this alone or with the United States? Because with a Golden Dome, there will be discussions that could have an impact on Canada, but Canada wouldn't be a part of them,” Carney said.
The Pentagon has warned for years that the newest missiles developed by China and Russia are so advanced that updated countermeasures are necessary. Golden Dome’s added satellites and interceptors — where the bulk of the program’s cost is — would be focused on stopping those advanced missiles early on or in the middle of their flight.
Canada and the U.S. are partners in the North American Aerospace Defense Command, the combined organization that provides shared defense of airspace over the two nations.
The newly elected Carney spent much spent much of the last few months saying the old relationship with the U.S. based on steadily increasing integration is over. Trump has infuriated Canadians by saying Canada should be the 51st state.
“We cooperate if necessary but not necessarily cooperate,” Carney said.
