Denmark`s Prime Minister Mette Frederiksen has reiterated that any attempt by the United States to seize Greenland would effectively mark the end of the NATO military alliance.

Speaking at the Munich Security Conference on Tuesday, Frederiksen said, "If one NATO member attacks another ally country, then NATO ends; it`s game over."

When asked if US interest in Greenland has subsided, Frederiksen responded, "Unfortunately not."

"I think the desire from the US president is exactly the same," she said referring to Donald Trump`s threats to seize the semi-autonomous territory of NATO ally Denmark for what he described as the purpose of national security.

Trump even suggested using military force to take control of the world`s largest island.

Frederiksen described Trump as "very serious" about controlling Greenland but said that Denmark remains open to discussions on strengthening Arctic security arrangements, though "there are clear limits to what can be negotiated."

Asked if a price could be placed on the island if US pressure continues, Frederiksen replied: "Of course not. Can you put a price on a part of Spain, or a part of the US, or a part of anywhere else in the world?"

She also stressed the importance of respecting sovereign states as a fundamental democratic principle. "The Greenlandic people have been very clear: they don`t want to become Americans," she said.

Frederiksen has previously warned that any attack on a NATO ally would be "the end of everything."

In early January, when Trump renewed his threats to seize Greenland, she said the Danish government was taking all measures necessary to protect the territory.

She said that she has been "very clear to Trump, in public and private, that we will do everything ... to defend fundamental democratic values and the international system we have built."

The tensions come as Trump seeks to assert greater control over Greenland and advance his plans to deploy the ‘Golden Dome` missile defense system - a multibillion dollar project he says will be operational before his term ends in 2029.

Trump claimed that NATO allies would have to step up their commitment to Arctic security to ward off what he described as threats from Russia and China.

The proposal has sparked international concern, particularly following the February 5 expiration of the New START treaty, the last remaining nuclear arms control agreement between the United States and Russia, which removed legally binding limits on the world`s two largest nuclear arsenals.

Russia has warned it may take military countermeasures if Washington proceeds with deploying elements of the system on Greenland.
