The United States, Denmark and Greenland have ‌entered into an agreement for the US to develop a significant military presence on Greenland, while prohibiting US adversaries from building their own bases on ‌the island, Donald Trump says.

The US president wrote on Truth Social on Friday that no US enemies would be able to make sensitive investments on the island without the approval of the US and that the agreement had no expiry date.

“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,” Trump wrote.

Trump’s 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.

He said, without elaborating, the US would soon be rolling out a large military presence on ⁠the island, which already hosts one Space Force base in its remote northwest.

“This is ‌a dream ​come true for the United States of America,” Trump wrote.

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.
