US To Establish Two New Military Bases In Greenland

The United States plans to open two new military bases in Greenland, an expansion made possible by a new security agreement between the US, Denmark, and the semi-autonomous Danish territory of Greenland.

On Tuesday, President Donald Trump, Danish Prime Minister Mette Frederiksen, and Greenland Prime Minister Jens-Frederik Nielsen signed the new security agreement during a trilateral ceremony at the United Nations General Assembly in New York.

The "agreement," which amends a 1951 defense treaty, allows the US "to establish an additional Defense Area at Narsarsuaq and Mestersvig in accordance with modalities and technical details to be mutually agreed by the Parties," which is where the two new military bases will be created.

Narsarsuaq hosted the US Bluie West One military base in the 1940s and 1950s. Mestersvig is a current military outpost used by the Danish special forces unit called Sirius Dog Sled Patrol.

The agreement also allows the US to "modernize and expand its activities" at its existing Pituffik Space Base in northwestern Greenland, create additional military facilities on the island, and enjoy greater military access by land, air, and sea.

It also bans non-NATO nations from establishing a military presence on Greenland and provides the U.S. with economic privileges (such as “minerals cooperation”) in the resource-rich island.

During a speech to assembled world leaders at the UN before the trilateral ceremony, Trump spoke of the "unprecedented agreement regarding the northern frontier of North America, the large and strategically vital piece of land known as Greenland."

This rhetoric tracked with Secretary of War Pete Hegseth’s vow in March to establish a "Greater North America." However, the agreement does not have the US take over Greenland, as leaders on the island, in Denmark, and throughout Europe had feared earlier this year.

Such fears were well placed, considering that the US conquered Venezuela in January, has been working toward regime change in Cuba, and is currently at war with Iran.

What's in the actual Greenland deal text? Analysis in the following: "The Danes lied the most: Trump is pretty much correct in saying that this new deal grants the US control of Greenland"...

Ok, we now have the actual text of the Greenland deal (https://t.co/HwqZT6CGb2), so we can say how it compares to the existing 1951 arrangement and who, between Trump and Denmark, lied the most in their framing of it.

Long story short - which may surprise some - the Danes lied… https://t.co/DPM2iFkN4v

Geopolitical commentator Arnaud Bertrand's breakdown of the official text and the implications:

1) This is now a permanent arrangement: whereas the existing 1951 deal only lasted as long as NATO existed, this one "does not have an end date and may only be amended by mutual consent." It even survives a hypothetical future independence of Greenland: in that event, Denmark and Greenland must ensure that the independent Greenlandic state "affirmatively assume[s] all of the rights and obligations of the Kingdom of Denmark specified in this Agreement."

2) In the 1951 agreement, the US could set up bases only where both governments agreed, and only on the basis of NATO planning. The new deal locks in three bases: the US can "modernize and expand its activities" at Pituffik, its only base in Greenland until now, and "shall be allowed to establish an additional Defense Area at Narsarsuaq and Mestersvig." Further bases beyond these 3 can be justified by the defense of "the American continent," a US interest rather than a NATO one. Also, quite subtle but this is interesting: Article IV(iii) says that "the United States may establish additional defense areas in Greenland" and that consultations are then held "to decide implementation details based on mutual agreement." What this means is that the principle of a new base is automatically granted and only the implementation details require agreement. Article VII also gives the US "the right to raise concerns regarding construction, or change of use" of any building near a US base, after which the parties decide together what to do. Which means that the US has a say over civilian planning around its bases.

3) On US military movement across Greenland, the wording change between the 1951 agreement and this new one is quite funny. The 1951 text said (Art. V(3)): the US "may enjoy... the right of free access to and movement between the defense areas through Greenland, including territorial waters, by land, air and sea," but only "in accordance with general rules mutually agreed upon and issued by the appropriate Danish authority in Greenland." The new one says: "the United States of America shall enjoy... the right of free access to and movement between the Defense Areas through Greenland, including the Territorial Waters, by land, air and sea." That's it: "May" becomes "shall," and the US military movement no longer has to follow rules "issued by the appropriate Danish authority in Greenland." The US also gets something new on top: "undersea access to and movement within the Territorial Waters," i.e. submarines.

4) Non-NATO exclusion: non-NATO states are barred from military installations or a persistent presence in Greenland unless all three parties approve, giving the US an effective permanent veto. The 1951 deal had no equivalent clause.

5) Investment screening: this is entirely new. "States or investors from a state that is not a member of NATO, a NATO partner, or an EU member state" (i.e. Russia, China, India, the Gulf States, etc.), "shall not be allowed to have (i) control, (ii) significant influence, or (iii) access to non-public information...within Particularly Sensitive Sectors or Activities in the territory of Greenland (including the Territorial Waters), unless agreed between the Parties." Again, it basically means that the US has a permanent veto over who can invest in strategic sectors in Greenland, as far as non-NATO or EU states are concerned.

6) Lastly, in stark contrast with the 1951 deal, the framing of the deal changes significantly: this new deal is largely framed around the US. The 1951 agreement existed only "for the benefit of the North Atlantic Treaty Organization." The new one lists the defense of "the American continent" as an objective, celebrates "the irreplaceable role" of the United States military as well as "the United States' indispensable historical and ongoing contributions to the security and defense of Greenland," and names the establishment of Trump's "Golden Dome" missile defense system as a key goal.

During his UN speech, Trump unleashed an extremely aggressive statement aimed at Tehran: "Will a deal be made with Iran that lets them rebuild and create a far greater country than it ever was before, maybe one of the greatest in the Middle East, or even the world? Or do I annihilate the Islamic Republic, and do it quickly, never giving them a chance to kill and destroy people and countries again? Do I drive them into hell with no chance of survival and no hope of future greatness or generations?"
