Inuit former parliamentarian Aqqaluk Lynge says US aggression towards Greenland/Kalaallit Nunaat has put the nation's people on edge.

In an interview with CBC Radio's As It Happens host Nil Köksal, Mr Lynge reinforced that Greenland - whose population is around 90 per cent indigenous Inuit - is a free and self-governing territory within the Danish commonwealth, which also consists of Denmark and the Faroe Islands.

Mr Lynge was one of the founders of the pro-independence party Inuit Ataqatigiit, but noted that the USA's imperialist designs on Greenland had changed the conversation.

"The question of independence can be solved in many ways, and we have already done that in Greenland in a manner that [is] very good for us. Denmark and Greenland are working closely together," he told CBC Radio.

"We had no problems until MAGA came in. So, what we need in Greenland is that we stick together.

"We are not negotiating independence right now. The world has changed so much that it's not on the table anymore. What is on the table is that Denmark needs Greenland and we need Faroe Islands together in the Danish commonwealth. We need the support from the outside world."

Mr Lynge said those who "are trying to destroy the connection between Denmark and Greenland will fail, because we are family".

"We have been together for 300 years. We are not about to separate from the world. It's the United States that are separating from the Western world. And that's something that everyone should care about," he said.

White House security advisor and longtime Trump ally Stephen Miller told CNN in a recent interview that Greenland "should be part of the United States" and, when pressed on the issue, refused to rule out taking it by force.

In the same interview, Mr Miller claimed the United States had the right to take control of energy resources in "its" hemisphere, alluding to the attack on oil-rich Venezuela and the kidnapping of its president Nicolas Maduro.

Greenland is believed to be rich in critical minerals and oil.

US President Donald Trump, who has long said Greenland should be part of the United States, has previously expressed a desire to annex Canada, is supportive of the movement to split resource-rich Alberta province from Canada, and has recently threatened the governments of Colombia, Mexico and Cuba.

Mr Lynge told CBC Radio that Greenland is part of Europe, part of Denmark, and part of the Nordic countries.

"We are part of the Western world, members of NATO. So why should [the] US do this to us?" he said.

"It's ridiculous for us, from here, to see what's going on. We are not an enemy. We have been friends with the United States for 80 years, at least. What's going on here?

"If they want anything with Greenland, why don't they talk to the Danish and Greenlandic governments, instead of using their social media to do everything?"

Recently, Mr Miller's wife Katie Miller posted an image on social media of Greenland branded with the American flag, with the caption "SOON".

"I think we have a very serious problem, and we need Canada's support," Mr Lynge said.

President Trump and others have argued the US needs Greenland for security reasons, with White House press secretary Karoline Leavitt citing "our adversaries in the Artic region" without naming any of those "adversaries".

Mr Lynge noted the USA has, after the end of the Cold War, wound back its military presence in Greenland by choice (it still possesses one base in the country).

"It's not us that have created the situation where their presence has been only up in the Thule airbase. So, the United States is solely responsible for this. We haven't done anything against them," the Inuit advocate said.

"It's really frustrating for us... I think that all of us in the Arctic must be ready for anything. And I'm sure that Denmark and Canada are talking to each other very closely. We are in a dangerous, very dangerous, situation right now.

"With the changing world that we are seeing, we need friends in Greenland, so we are very much welcoming the new office here. And it is important, also, that after Maduro, they are talking about Colombia. Maybe Canada is the next, and then Greenland."

Mr Lynge said the situation is "really something that the Greenlanders are very nervous about".

"I think that the vast majority of Greenlanders want a steady connection to Denmark through the arrangements that we have. That's the only freedom we have," he told CBC Radio.

"The world must understand that Greenland is not about to do anything other than negotiating with Denmark, our closest ally for 300 years, and there's nothing that we intend to separate from Denmark. That's not the case. We are not separatists.

"I think that Greenlanders are mostly nervous that anything could happen. And that is how we look at the United States now. Regular people, they don't trust the United States anymore."
