Location, location, location: Greenland’s position above the Arctic Circle makes the world’s largest island a key part of security strategy. But for whom?
Increasing international tensions, global warming and the changing world economy have put Greenland at the heart of the debate over global trade and security, and U.S. President Donald Trump wants to make sure his country controls this mineral-rich island that guards the Arctic and North Atlantic approaches to North America.
Greenland is a self-governing territory of Denmark, a longtime U.S. ally that has rejected Trump’s overtures. Greenland’s own government also opposes U.S. designs on the island, saying the people of Greenland will decide their own future.
The island, 80% of which lies above the Arctic Circle, is home to about 56,000 mostly Inuit people who until now have been largely ignored by the rest of the world.
Here’s why Greenland is strategically important to Arctic security:
Greenland’s location is key
Greenland sits off the northeastern coast of Canada, with more than two-thirds of its territory lying within the Arctic Circle. That has made it crucial to the defense of North America since World War II, when the U.S. occupied Greenland to ensure it didn’t fall into the hands of Nazi Germany and to protect crucial North Atlantic shipping lanes.
Following the Cold War, the Arctic was largely an area of international cooperation. But climate change is thinning the Arctic ice, promising to create a northwest passage for international trade and reigniting competition with Russia, China and other countries over access to the region’s mineral resources.
Security threats to the Arctic
In 2018, China declared itself a “near-Arctic state” in an effort to gain more influence in the region. China has also announced plans to build a “Polar Silk Road” as part of its global Belt and Road Initiative, which has created economic links with countries around the world.
Then-U.S. Secretary of State Mike Pompeo rejected China’s move, saying: “Do we want the Arctic Ocean to transform into a new South China Sea, fraught with militarization and competing territorial claims?”
Meanwhile, Russia has sought to assert its influence over wide areas of the Arctic in competition with the U.S., Canada, Denmark and Norway. Moscow has also sought to boost its military presence in the polar region, home to its Northern Fleet and a site where the Soviet Union tested nuclear weapons. Russian military officials have said that the site is ready for resuming the tests, if necessary.
The Russian military in recent years has been restoring old Soviet infrastructure in the Arctic and building new facilities. Since 2014, the Russian military has opened several military bases in the Arctic and worked on reconstructing airfields.
European leaders’ concerns were heightened following Russia’s full-scale invasion of Ukraine in 2022. Last year, Russian President Vladimir Putin noted that Russia is worried about NATO’s activities in the Arctic and will respond by strengthening the capability of its armed forces there.
“Russia has never threatened anyone in the Arctic, but we will closely follow the developments and mount an appropriate response by increasing our military capability and modernizing military infrastructure,” Putin said in March at a policy forum in the Arctic port of Murmansk.
He added, however, that Moscow was holding the door open to broader international cooperation in the region.
U.S. military presence in Greenland
The U.S. Department of Defense operates the remote Pituffik Space Base in northwestern Greenland, which was built after the U.S. and Denmark signed the Defense of Greenland Treaty in 1951. It supports missile warning, missile defense and space surveillance operations for the U.S. and NATO.
Greenland also guards part of what is known as the GIUK (Greenland, Iceland, United Kingdom) Gap, where NATO monitors Russian naval movements in the North Atlantic.
