Trump promises to 'invest billions of dollars' in Greenland if they choose to become a part of the United States

Despite Greenland's prime minister reiterating that his people do not wish to be Americans, President Donald Trump is persisting in his campaign to one day incorporate the country into a part of the US.

As the 78-year-old Republican attempts to persuade political parties in Greenland to get behind his rallying call ahead of the nation's parliamentary election tomorrow (March 11), he has now promised to 'invest billions of dollars' into its infrastructure.

There are six main parties vying for election, with 31 seats up for grabs and 16 needed for a majority.

The key theme of the election is independence, with only one party, the left-wing Naleraq, having pledged to work with the US - although it does not wish for Greenland to become a US territory.

Taking to Truth Social, Trump posted: "As I made clear during my Joint Address to Congress, the United States strongly supports the people of Greenland’s right to determine their own future. We will continue to KEEP YOU SAFE, as we have since World War II.

"We are ready to INVEST BILLIONS OF DOLLARS to create new jobs and MAKE YOU RICH — And, if you so choose, we welcome you to be a part of the Greatest Nation anywhere in the World, the United States of America!"

It came just four days after Greenland's Prime Minister Múte Bourup Egede, of the socialist Inuit Ataqatigiit party, issued a stern reply to Trump - after he said the US was going to 'get' the world's biggest island 'one way or the other'.

Taking to his Facebook, Egede posted on Wednesday (March 5): "Kalaallit Nunaat [Greenland] is ours.

"We don’t want to be Americans, nor Danes; We are Kalaallit. The Americans and their leader must understand that. We are not for sale and cannot simply be taken. Our future will be decided by us in Greenland."

Addressing Congress on Tuesday (March 4), the 47th POTUS gave a somewhat confusing message to Greenlanders.

"If you choose, we welcome you into the United States of America," Trump said.

"We need Greenland for national security and even international security.

"And we’re working with everybody involved to try and get it. But we need it really for international world security."

Despite seemingly offering 'the incredible people of Greenland' the choice to 'determine [their] own future,' Trump then resolved: "And I think we’re going to get it - one way or the other, we’re going to get it."

And the president's speech concluded with: "We will keep you safe. We will make you rich. And together, we will take Greenland to heights like you have never thought possible before.

"It’s a very small population but very, very large piece of land and very, very important for military security."
