Donald Trump allies declare Greenland should be controlled by the US as Nato nations fear alliance on the brink of collapse

But Mr Miller, who is the former chief spokesman for Mr Trump, denied there would be an "invasion" of Greenland, branding the claims a "silly distraction".

"We do need Greenland, absolutely. We need it for defence," he told GB News.

"He is not going to invade Greenland. I think what this is, is the mainstream media trying to distract away from the fact that President Trump brought to justice a narco-terrorist in Nicolas Maduro, and that he's going to actually restore democracy to the people of Venezuela.

"And so the the whole thing on the Greenland front, I mean, Greenland should be a territorial area that's controlled by the United States. I think the US could do a much better job of maximising that area, especially with those shipping lanes opening up in the Russians and the Chinese, pushing their military into the Arctic Circle in that part of the world.

"But no, there's not going to be an invasion of Greenland. That's just a silly distraction."

Advocating for Mr Trump further, Mr Miller added: "I think the US, quite frankly, could do a much better job than Denmark.

"And Denmark is a great country and their strong allies, but let's keep the focus where it is, and that's that President Trump is making the world a safer place. I love what he was able to pull off in Venezuela with just swooping in in the dead of night to pull that off, but Greenland should be in the US category."

Making clear his stance on Greenland, White House deputy chief of staff and homeland security adviser Stephen Miller bluntly declared that the territory "should be part of the United States".

Pressed on whether direct military intervention was on the cards for Donald Trump, Mr Miller said: "Nobody's gonna fight the United States militarily over the future of Greenland.

"What is the basis of their territorial claim? What is their basis of having Greenland as a colony of Denmark? The United States is the power of Nato.

"For the United States to secure the Arctic region, to protect and defend Nato and Nato interests, obviously, Greenland should be part of the United States, and so that's a conversation that we're going to have as a country."

He added: "We’re a superpower and under President Trump, we are going to conduct ourselves as a superpower.

"There's no need to even think or talk about this in the context that you're asking, of a military operation. Nobody's going to fight the United States militarily over the future of Greenland."

Issuing a stark warning to the US President, Denmark's Prime Minister Mette Frederiksen said an attack by Donald Trump on Greenland would result in the "end of everything", including Nato.

Mr Frederiksen told Danish television network TV2: "If the United States decides to militarily attack another Nato country, then everything would stop – that includes Nato and therefore post-second world war security.

"You cannot go in and take over part of another country’s territory. If the US chooses to attack another Nato country, everything will stop.

"I have said from the beginning that I unfortunately believe the American president is serious about this. I have also made it very clear where Denmark stands. And Greenland has repeatedly said that it does not want to be part of the USA."

Frederiksen also made clear that her government was doing all that was possible to prevent an attack on Greenland and accused the US of applying "unacceptable pressure", describing it as an "unreasonable attack on the world community".
