US ownership of Greenland is the path to environmental insecurity.
Every generation or so, some American politician gets the notion that the United States ought to acquire Greenland. Often, this is justified by reference to the Monroe Doctrine, proclaimed in the 1820s, which proclaimed that European powers should stay out of the Americas. However, this is a rather silly attempt to dignify acquisition of Greenland, which has been part of the Kingdom of Denmark for one thousand years. Long before Columbus discovered America, the Vikings had explored Iceland and Greenland. The idea that the Monroe Doctrine applies to events more than eight centuries before it was proclaimed is absurd. Nor is the US close to Greenland, which lies between Iceland and the coast of Canada. The people of Greenland do not want to be bought or sold. Nor does Denmark want to sell Greenland.

Whatever the justification for buying (or seizing) Greenland, there are two reasons why its acquisition looks attractive: Natural resources and military bases. There seldom seems to be any US government interest in the Greenlanders themselves, whose language and culture could easily be utterly destroyed after acquisition. There are only about 60,000 people living on the vast island, much of which is frozen all year round. Almost the entire population lives along the southwestern coast, one third in the capital, Nuuk. There are no roads connecting most of the towns together.
In military terms, Greenland looks important because it is halfway between Washington and Moscow. For that reason, the Americans already have one base on the island, Thule, which is on the west coast, just about the only settlement in the far north. Another American base, called Century, was located inland on the great Greenland ice sheet. Established in 1959 in a series of tunnels and excavations into the ice sheet, it was occupied full time until 1964, it became a seasonal base (closed in winter), and then was abandoned in 1967. Today it lies buried in ice and snow that have since accumulated. In other words, at the height of the Cold War, the US did not find it necessary, and they found it expensive and difficult, to maintain an inland base. Greenland has an extreme environment, and after struggling to sustain bases, it became clear that the Soviets could hardly sneak in and create a meaningful military site, much less continually supply one. It is exceedingly difficult to move around on the inland surface of Greenland, which is why almost all communities are on the coast. In short, this is not a place for ground forces, base camps, and troop movements. It is rather a place for early warning systems and other equipment designed to monitor the sea and the sky. Denmark is a member of NATO, and in addition the Americans have a treaty with the Danish government, allowing them to operate the Thule military base. They can also move ships and submarines around the coast to their heart's content. In short, from a military perspective, owning Greenland will not suddenly improve American security, and if new bases are necessary (although no one seems to have said they are) that could be negotiated. I cannot see any important military advantage to be gained. "National security" is a bogus argument for acquiring Greenland.
In terms of resources, Greenland potentially is a bonanza. Even with much of it explored primarily from the air, it is clear that it has uranium, rare earth minerals, oil, and gas, with potentially far more still undiscovered. Why have these resources not been exploited already? First, there is the high cost of development. There are no harbors convenient to or roads to most of these resources. The weather makes it difficult or impossible to operate outside for much of the year. Such practical problems make it uncompetitive with other locations where resources are more accessible. The second reason is important. Many Greenlanders fear that an influx of mining companies will despoil the landscape, pollute the environment, and undermine their way of life. Possibly some limited mining could be negotiated, provided strong environmental safety regulations are enforced. However, the US has a disgraceful history with mining on Native American lands, notably with the uranium mining of Navajo land. More than 30 million tons of uranium ore was extracted. As the American Environmental Protection Agency summarizes, "a legacy of uranium contamination remains, including over 500 abandoned uranium mines as well as homes and water sources with elevated levels of radiation. Potential health effects include lung cancer from inhalation of radioactive particles, as well as bone cancer and impaired kidney function from exposure to radionuclides in drinking water." The mines were closed in 1986, but even in 2025 after spending more than $1 billion, many of the mines are not cleaned up. Something similar could easily in Greenland if mining companies operated with the weakened standards and poor oversight likely under the Trump administration.
Furthermore, if oil drilling is permitted, Greenland will contribute to the global warming that already is melting their ice sheet. This is not a small matter. Greenland impounds an astonishingly large portion of the earth's fresh water. Its ice has been shrinking every year for 28 years. The United Nations estimates that during 2024 it lost "50 million litres per minute, 9,000 million litres per hour" for a total of 80 gigatons of water during that single year. Scientists estimate that were all of Greenland's ice to dissolve into the sea, the oceans would rise about 7 meters. If CO2 emissions are not drastically reduced, within one lifetime the ice melt from Greenland (with even more water released from Antartica) will flood coastal cities in all parts of the world, including Copenhagen, New York, much of Bangladesh, about half of Florida, and many island nations, to make a suggestive short list. Greenlanders take global warming seriously, but the current President of the United States does not. Trump calls global warming a hoax, and he is passing legislation designed to increase fossil fuel exploration and consumption. If the he acquires Greenland, it will be in order to "Drill, baby drill." This makes the United States the worst possible owner of Denmark.
Ownership of Greenland is a matter of security. But it is not a matter of American military security but the security of Greenland, as a landscape and a people. Allowing the United States to seize Greenalnd endangers the world's environmental security. It also violates a fundamental principle of international law: respect for international borders.
