Europe Braces for Geopolitical Showdown Over Trump’s Greenland Ambitions

Donald Trump’s threats to acquire — or even militarily seize — Greenland are no longer dismissed as eccentric rhetoric. They are now viewed as a direct geopolitical risk, triggering global alarm.

“We must be ready for a direct confrontation with Trump,” stated an EU diplomat briefed on ongoing discussions regarding Greenland. “He is in an aggressive state, and we must be prepared.”

U.S. Secretary of State Marco Rubio announced Wednesday plans to discuss the potential U.S. acquisition of Greenland with Danish officials next week. The White House indicated Trump’s preference for a negotiated purchase of the island, but also suggested a military takeover remains a possibility.

Politico spoke with officials, diplomats, experts, and NATO executives, who were granted anonymity to speak freely, to map out how Europe could deter the former U.S. president and what its options are should he proceed.

Seeking Compromise

Trump argues Greenland is vital to U.S. security interests, accusing Denmark of insufficient efforts to protect it from rising Chinese and Russian military activity in the Arctic.

A negotiated settlement allowing Trump to claim a “win” while enabling Denmark and Greenland to save face may offer the quickest exit from the dilemma.

A former senior NATO official suggested the alliance could mediate between Greenland, Denmark, and the U.S., similar to its role with Turkey and Greece.

U.S. Ambassador to NATO, Matthew Whitaker, stated Wednesday that Trump and his advisors believe Greenland is not adequately secured. “As the ice melts and as the routes in the Arctic and the Far North open up… Greenland becomes a very serious security risk for the mainland of the United States of America.”

NATO allies are also exploring new proposals to Trump that could bolster Greenland’s security, despite widespread belief that any immediate threat from Russian and Chinese vessels to the region is overstated.

Among other proposals, the Alliance should consider accelerating Arctic defense spending, conducting more military exercises in the region, and deploying troops to secure Greenland and reassure the U.S. if necessary, according to three NATO diplomats.

The alliance should also be open to creating an “Arctic Sentry” scheme — moving military assets to the region — similar to the Eastern Sentry and Baltic Sentry initiatives, two of the diplomats noted.

“Anything that can be done” to strengthen the alliance’s presence near Greenland and satisfy Trump’s demands “must be fully utilized,” one of the aforementioned NATO diplomats said.

Trump also cites Greenland’s vast mineral deposits and potential oil and gas reserves as a reason for acquisition. However, a key reason Greenland remains largely undeveloped is the difficulty and high cost of extracting resources from its inhospitable terrain, making them less competitive than Chinese imports.

Danish envoys report years of efforts to advocate for investment in Greenland, but European counterparts have been unreceptive. An EU diplomat familiar with the matter, however, suggests this stance is shifting.

Offering Massive Funds to Greenland

The Trump administration has strongly supported Greenland’s independence movement. The argument posits that if the Arctic region separates from the Kingdom of Denmark and signs an agreement with the U.S., it would be flooded with American money.

While Trump has repeatedly refused to rule out military force to seize Greenland, he also insists he wants the annexation to be voluntary.

The EU and Denmark are working to convince Greenlanders they can offer a better deal.

Brussels plans to more than double its spending on Greenland from 2028, as part of long-term budgets drafted after Trump began asserting claims over the Danish-controlled territory, according to a European Commission draft proposal published in September.

Under the plans, which are subject to further negotiations among member states, the EU would nearly double spending on Greenland to €530 million over a seven-year period starting in 2028. This comes in addition to funds Denmark sends to Greenland as part of its agreement with the self-governing region.

Greenland would also be eligible to apply for an additional €44 million in EU funding for remote areas connected to European countries, the same document indicates.

Danish and European support currently focuses primarily on welfare, healthcare, education, and the region’s green transition. Under the new spending plans, this focus would expand to developing the island’s capacity to mine mineral resources.

An attractive offer from Denmark and the EU could be sufficient to keep Greenlanders outside American control.

Considering Economic Retaliation

Since Trump’s first term, “a lot of effort has gone into thinking about how to ensure European security, Nordic security, Arctic security, without active U.S. participation,” stated Thomas Crosbie, a U.S. military expert at the Royal Danish Defence College. “That’s difficult, but it’s feasible. But I don’t know if anyone has seriously thought about ensuring European security against America. It’s just crazy,” Crosbie added.

The EU possesses a powerful political tool that could deter Trump: the Anti-Coercion Instrument, a “trade bazooka” created after the first Trump administration, which allows the EU to retaliate against trade discrimination.

The EU threatened to use it after Trump imposed tariffs on the bloc but shelved it in July after both sides reached an agreement. With the U.S. still imposing tariffs on the EU, Brussels could reactivate the “bazooka.”

“We have exports to the United States just over €600 billion, and for about one-third of these goods, we have a market share of over 50%, and it is absolutely clear that this is also the power in our hands,” said Bernd Lange, chair of the European Parliament’s trade committee. However, Trump would need to believe the EU means business, given that its previous tough talk ultimately led to no action.

Deploying Troops on the Ground

If the U.S. does decide to seize Greenland by military force, Europeans would have limited options to prevent it.

“They are not going to preemptively attack the Americans before they claim Greenland, because that would be before an act of war,” said Crosbie, the Danish military instructor. “But in terms of responding to the first move, it really depends. If the Americans have a very small group of people, you could try to arrest them, because it would be a criminal act.” It’s a different story if the U.S. attacks with full force.

Legally, Denmark might be compelled to respond militarily. A standing order from 1952 mandates troops to “immediately commence battle without waiting or seeking orders” in “case of an attack on Danish territory.”

European countries should consider deploying troops to Greenland — if Denmark requests it — to increase the potential cost of a U.S. military action, an EU diplomat suggested, echoing proposals that Berlin and Paris could send forces to deter any invasion.

While these forces are unlikely to withstand a full U.S. invasion, they would serve as a deterrent.
