President Trump signed a trilateral security agreement with Denmark and Greenland on the sidelines of the U.N. General Assembly, expanding America's Arctic military footprint while global conflicts underscore the island's strategic value.
The deal, announced Friday and signed Tuesday in New York, grants the United States permanent control over security operations in Greenland and bars any U.S. adversary from establishing a military presence on the island without Washington's written approval. Greenland remains under Danish sovereignty, but the American military gains far more room to operate on the world's largest island, a frozen landmass sitting between North America and Europe at the top of the Arctic.
Trump called the agreement a landmark. "This is tremendous for Europe and for the United States and for everybody. And for Greenland, it's going to be incredible," he said at the signing, Breitbart reported. Danish Prime Minister Mette Frederiksen described it as "a deal that can last forever."
The agreement calls for two major new military installations in Greenland, a significant expansion from the roughly 200 American soldiers currently stationed at Pituffik Space Base, the Department of Defense's northernmost installation. Pituffik, formerly known as Thule, already houses early-warning missile detection systems, satellite guidance and control capabilities, and a large airfield critical to U.S. defense posture in the Arctic.
Under the deal's terms, only NATO and EU members will be permitted to make what the agreement calls "sensitive investments" in Greenland. The provision stops short of granting exclusive U.S. mining concessions but effectively locks out China and Russia from gaining an economic foothold on the island, National Review noted.
Trump framed the arrangement as cost-free for American taxpayers. He said the deal gives the U.S. "permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many U.S. concerns," and that it comes at "NO COST" to the U.S. government, the Washington Examiner reported.
Full details of the agreement have not yet been made public.
The deal arrives at a moment when two active conflicts are forcing Western governments to rethink energy supply chains and strategic geography. The war in Ukraine has exposed how quickly energy infrastructure can be disrupted. Meanwhile, the Iran conflict has threatened shipping through the Strait of Hormuz, one of the world's most critical oil chokepoints.
Robert Price, CEO of Greenland Energy Company and president of USFM Corporation, told Fox News Digital that those conflicts are exactly why his companies are pursuing oil and mineral exploration on the island.
"One of the reasons that we are exploring for oil in Greenland is because of what's going on in the Strait of Hormuz right now."
Price's companies are working two fronts. On Greenland's eastern side, Greenland Energy Company holds oil exploration licenses in an area Price described as geologically similar to the North Sea, one of the world's most productive petroleum basins. The company is pursuing permits for an exploratory oil well planned for 2027. On the western side, USFM Corporation is drilling around Disko Island for nickel, copper, palladium, and cobalt, metals essential to everything from batteries and power generation to smartphones and military hardware.
Price compared the Disko Island district to Norilsk, Russia, one of the world's most mineral-rich regions. He said the area "could be one of the largest mining districts in the world." But Fox News noted that the scale Price described has not been proven, with exploratory drilling still underway.
Trump's interest in Greenland has drawn skepticism and mockery from critics since he first raised the idea of acquiring the territory. But the security agreement vindicates the strategic logic behind that focus. The president had previously shared an American-flag map spanning Greenland, signaling the depth of his ambitions for Arctic engagement.
Price made the resource argument in blunt terms. American dependence on hostile or rival nations for rare earth minerals and critical metals represents a vulnerability that Greenland's geology could help close.
"We don't want to be dependent on China for our rare earth minerals, and we don't want to be dependent on Russia for them either."
He added that critical minerals "touch every part of our lives, which includes our cellphones, our computers, batteries, power storage, power generation." The agreement, Price said, shores up the long-term investment climate that projects like his require. Oil and mineral extraction in the Arctic demands years of capital commitment before a single barrel or ton of ore reaches market.
"What it does is it shores up long-term investment in Greenland, and that's what our projects are. They're long-term investments from oil, gas, and minerals."
Price said he and his teams are "really excited about this agreement."
The trilateral structure lets all three parties claim a win. Denmark and Greenland preserve sovereignty, a non-negotiable demand from Copenhagen throughout months of tension over Trump's repeated public statements about acquiring the island. The United States gains permanent military rights, veto power over adversary access, and a framework that channels future investment toward allied nations.
National Review acknowledged that the strategic outcome may prove positive but argued the diplomatic path was unnecessarily rough on NATO alliances. The publication urged the administration to "repair the diplomatic damage that this episode has caused by rebuilding a deeper relationship with Denmark and Greenland."
Whether that damage lingers or fades will depend on execution. Ratification is still pending, and the full text of the agreement has not been released. Open questions remain about the specific capabilities the two new bases will house, the timeline for construction, and whether Greenland's government secured any economic concessions beyond the investment restrictions.
What is already clear is the strategic logic. The Arctic is warming, opening new shipping lanes and exposing mineral deposits that were locked under ice for millennia. Russia has been expanding its Arctic military presence for years. China has declared itself a "near-Arctic state" and sought investment footholds in Greenland. The United States, until now, had one aging base and a lot of talk.
This deal changes the math. Two new bases, a permanent security mandate, and a framework that blocks adversary investment give Washington a real footprint in a region that is only going to matter more.
Critics spent years mocking the idea that Greenland mattered. Wars, supply chain fractures, and a shifting Arctic have answered them.
