The US President has resumed his pursuit to gain control of Greenland.

In a Truth Social post on Saturday morning, Donald Trump wrote that the US had “entered into an agreement” with Denmark and Greenland.

He said the agreement would give the US “permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many U.S. concerns”.

“At my direction, we worked with representatives of Denmark and Greenland to guarantee that the United States will FOREVER have the complete ability to do what is necessary in Greenland in order to secure and defend the security of Greenland, and the United States of America,” Mr Trump wrote.

“Additionally, from now on, no U.S. adversary can EVER have a base in Greenland, have a military presence in Greenland, or make sensitive investments in Greenland, without our express written approval.”

He claimed that presidents had recognised the “strategic importance” of Greenland for 100 years but had failed to address it.

“I am proud to be the President that permanently and conclusively addressed this very important situation,” Mr Trump said.

“This is an ‘Infinite Life’ Agreement, there is no end!

“We are very honored and proud of what has just taken place, and everything agreed to today will be cherished by the American People.”

Mr Trump said there would be no cost to the American people.

The announcement suggests he was pleased with the outcome of the negotiations, and that he may not revive his territorial claims, at least in the near future.

“We will immediately begin the process of developing a large Military presence in the appropriate part of Greenland, of which there are many.

“We will work with the people of Greenland in its development and construction.

He said the “solution” would be great and beneficial to the US, Denmark, Greenland, and all allies.

“We look forward to working with the wonderful people of Denmark and Greenland toward a magnificent future with respect to this large, and highly strategic, parcel of land. We will be very protective of it!

“This is a dream come true for the United States of America, one that is very important, historic, and special.”

The Danish Prime Minister’s office said the agreement would strengthen North Atlantic and Arctic security.

Much was unclear as of Friday night, including whether any new US bases would be constructed as a result of the agreement. Trump’s posts about negotiations or agreements often lack context or specifics.

The US already has nearly total overflight and basing rights in Greenland due to a 1951 treaty.

It was also unclear how the agreement would be received in Greenland, an autonomous territory of Denmark. The island’s residents aspire to independence and have bristled at US attempts to assert hegemony.

In a separate statement, US Secretary of State Marco Rubio said the deal “permanently and completely” addressed Washington’s national security concerns with respect to the island.

“Greenland will forever be part of the strategic defence area of North America and exclude any adversary from it and the surrounding area,” he wrote.

A State Department official, speaking on condition of anonymity to discuss specific terms, said the deal prohibits non-NATO countries from building a base in Greenland, and will allow only the US and its allies to make unspecified “sensitive investments.”.

The official said the agreement grants the US permanent access, basing and overflight rights, and would continue to apply even if Greenland becomes independent.
