Donald Trump says the Greenland agreement gives the U.S. permanent control over security and all other needs

President of the United States, in a post on his Truth Social account, cross-posted to his X account

I am pleased to announce that the United States of America has entered into an Agreement with The Kingdom of Denmark, and Greenland, that gives the United States permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many U.S. concerns. There will be NO COST to the United States! 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.

Original post on Truth Social (@realDonaldTrump). Read on the trumpstruth.org archive (status 41803), which reproduces the full text, shows the original post date 'Friday, September 18, 2026, 05:18 pm EDT', the Truth Social status ID 117294126158197822 and the original URL, and records a capture at 7:15 AM EDT on September 19. truthsocial.com itself returns a Cloudflare 403 to automated requests and was not opened. The post ID decodes to 21:18:49 UTC, which matches 5:18 PM EDT. The identical text was posted on X at 8:12 PM EDT (next source). After the quoted span the post adds that from now on no U.S. adversary can have a base, military presence or sensitive investments in Greenland without the United States' 'express written approval', and calls the deal an 'Infinite Life' Agreement; those sentences are outside the quotation but in the same post.

Trump announces agreement with Denmark to secure 'permanent' control over Greenland's security (opens in a new tab) · NBC NewsParagraphs stating that Greenland's government took part in negotiations, that the agreement is expected to be signed next week around the UN General Assembly, and that its full text has not been released.

About this source

Read via curl; JSON-LD shows published 2026-09-18 22:37 UTC (6:37 PM EDT) and last modified 2026-09-19 08:15 UTC (4:15 AM EDT). Used for three statements: Greenland's government took part in negotiations alongside Denmark and the U.S.; Denmark said the agreement is expected to be signed next week in connection with the UN General Assembly; the full text had not been released. The BBC page (modified 7:36 AM EDT) and TV 2's live blog on the morning of September 19 also say the text is unpublished.

Before the quotation

Trump had repeatedly argued that control of Greenland was necessary for U.S. national security, and Greenland's government had been taking part in negotiations with Denmark and the United States on the island's security. The post was published at 5:18 PM EDT on Friday, September 18, 2026.

After the quotation

Fox News Digital published Secretary of State Marco Rubio's statement and a senior U.S. official's description of the agreement at 5:19 PM EDT. Later on Friday, Frederiksen and Greenland's leaders issued statements, Denmark said the agreement is expected to be signed the following week in connection with the UN General Assembly, and NBC News reported that its full text had not been released.

How this statement is classified

Defended or excused

Case context: Trump’s “permanent control” description of the announced U.S.-Denmark-Greenland security agreement

The label describes this statement’s response within the context above.

Why this label?

The case's fixed reference point is Trump's own description, in this post, of the not-yet-signed agreement as giving the United States permanent control over security and all other needs in Greenland. In the quoted passage Trump states that description himself, says the United States will forever have the complete ability to do what is necessary there, and presents the agreement as a completed result at no cost to the United States, which affirms and endorses the deal as he characterizes it. The closest competing label is mixed_or_conditional, because the full post also says the United States will work with the people of Greenland and calls the solution good for Denmark, Greenland and allies. That loses because those lines add to the endorsement instead of qualifying it, and the post states no condition or reservation.

I'm looking forward to the ink being dry on the new agreement with the USA. And to us being able to see the content. Until then, I'm skeptical. I don't have much confidence in Trump.

We will have to wait with that until the agreement is published next week. So I don't have many comments on that.

Next week could be a good week… For Greenland, Denmark and the USA alike. Where a long period of uncertainty is hopefully replaced by a binding agreement that strengthens security in the Arctic and the North Atlantic and thus also our shared security in NATO and Europe - with respect for the Kingdom's red lines.
