Trump says oil, gas and mineral exploration in Greenland is set to begin. It's not that simple

U.S. President Donald Trump said “massive” oil, gas and mineral exploration is set to begin in “our new and beautiful Greenland ” early Wednesday.

It wasn’t immediately clear what exploration or developments the U.S. president was referring to in his post, and Greenland is a self-governing territory of Denmark, rather than a part of the United States.

Trump posted on his Truth Social platform following a campaign event Tuesday in Wasilla, Alaska , to stump for Republican U.S. Sen. Dan Sullivan as he seeks his third term to represent the state in an election against Democratic former U.S. congresswoman Mary Peltola.

Rising energy prices — a direct result of Trump’s war in Iran — are creating serious and sustained financial hardships for America’s working class ahead of the midterm elections next month. Trump’s comments Wednesday are likely aimed at addressing voters’ concerns before they head to the polls.

But despite Trump’s optimism, resource exploration and extraction in Greenland has stymied companies for decades thanks to the island’s harsh climate , lack of key infrastructure and difficult geology. Previous efforts to extract so-called rare earth minerals, as well as oil and gas, have never progressed beyond the exploratory stage.

Trump’s comments about the Arctic island come less than a month after he signed an agreement with the leaders of Denmark and Greenland to strengthen security in the Arctic and North Atlantic following months of tensions with NATO allies over the U.S. president's repeated demands to take control of the semiautonomous Danish territory. It does not grant the U.S. any special exploration rights, but does place some limits on investments by non-NATO countries in strategic sectors.

The deal also paved the way for more U.S. bases in Greenland and eased tensions over Trump's repeated calls for Greenland to become part of the United States. The agreement would still apply if Greenland eventually chooses independence.

Trump has expressed his desire to acquire Greenland since as long ago as 2019 and, during his second term, issued threats to seize the territory from Denmark, a NATO ally.

Representatives of the leaders of Denmark and Greenland did not immediately return requests for comment Wednesday.

Greenland has large deposits of the rare earth minerals that are needed to make everything from computers and smartphones to the batteries, solar and wind technologies that will power the transition away from fossil fuels. China currently dominates the world's supply of these critical minerals and the Trump administration is seeking to break Beijing's chokehold on them.

The U.S. Geological Survey has also identified major potential offshore deposits of oil and natural gas.

But tapping these resources could be prohibitively difficult: the rare earth minerals are encased in rock, and the offshore oil and natural gas deposits are covered by Arctic ice.

Trump's Truth Social post also touted Greenland's strategic location, saying that “from a Security Purpose in the Defense and Offense of both the United States of America, and Europe,” the island is “second to none.”

“Any future attack on the United States will have to come across Greenland, where our Defense will routinely knock down drones, missiles, or any other form of weapon not yet even conceived," he wrote. "It gives us time, location, and sightline, like nowhere else in the World!”

The United States was prominent in Greenland for decades but, since 1945, the U.S. military presence in Greenland has decreased from thousands of soldiers on 17 bases and installations to roughly 200 soldiers on the remote Pituffik Space Base in the northwest. The base supports missile warning, missile defense and space surveillance operations for the U.S. and NATO.

Trump said last month that the U.S. would “immediately begin the process of developing a large military presence in the appropriate locations,” including “building two very major military bases.”
