COPENHAGEN – The red baseball caps say it plainly: “Make America Go Away.” In Denmark and Greenland, the spoof of Donald Trump’s Maga hats has become a brisk-selling emblem of defiance after the US president’s latest threats to seize the vast Arctic territory.
Early batches of the caps, created by Copenhagen vintage-clothing store owner Jesper Rabe Tonnesen, drew little interest in 2024. Then rhetoric from Washington intensified over Greenland – and demand leapt from a trickle to selling out in a single weekend. Tonnesen says he has now ordered “several thousand.”
“When a delegation from America went up to Greenland, we started to realise this probably wasn’t a joke – it’s not reality TV, it’s actually reality,” said Tonnesen. “So I said, ‘OK, what can I do?’ Can I communicate in a funny way with a good message and unite the Danes to show that Danish people support the people of Greenland?”
At a weekend rally in freezing weather outside Copenhagen city hall, protesters waved Danish and Greenlandic flags and held handmade placards. “No Means No,” read one sign. Another declared, “Make America Smart Again.” “I want to show my support to Greenland and also show that I don’t like the president of the United States,” said local resident Lars Hermansen, under a red cap. Another cap-wearer, Kristian Boye, said the gathering kept a lighthearted tone with a serious point: “I’m here to support the Greenlanders, who are going through a very hard time right now. They are being threatened with having their country invaded. I think it’s totally unacceptable.”
The original cap Tonnesen designed carried a Danish wordplay – “Nu det NUUK!” – twisting the phrase “Nu det nok” (“Now it’s enough”) by substituting Nuuk, Greenland’s tiny capital.
From street meme to sovereignty line
The hats may be witty, but the politics behind them are not. What began as a niche Copenhagen joke has tipped into a broader argument about who gets to decide Greenland’s future – and on what legal basis. European capitals have rallied around Denmark and Greenland, sharpening reminders that Greenland is part of the Kingdom of Denmark and sits under NATO’s collective-defense umbrella. Finland’s foreign minister stated publicly in 2025 that Greenland is protected by Article 5 of NATO, a point rooted in the treaty’s geography clause covering “islands under the jurisdiction of any of the Parties in the North Atlantic area north of the Tropic of Cancer.”
Under Denmark’s constitutional order, Greenland has extensive autonomy. The Self-Government Act that entered into force on June 21, 2009, recognizes Greenlanders as a people with a right to self‑determination in international law and allows Greenland to assume additional competencies as it chooses. Critically, Chapter 8 sets out a clear, democratic path to independence: any change in sovereignty must come through a decision by the people of Greenland and subsequent agreements endorsed by both the Greenlandic parliament and the Danish Folketing. There is no legal avenue for a third country to acquire Greenland absent that consent. The act, published by the Danish Prime Minister’s Office, now functions as the core constitutional framework for relations between Copenhagen and Nuuk.
International law further constrains any talk of forcible “acquisition.” Article 2(4) of the UN Charter prohibits the threat or use of force against the territorial integrity or political independence of any state – a cornerstone principle widely regarded as customary international law. For policymakers in Europe and beyond, that turns the rhetorical “purchase” of another country’s territory into a test of whether leaders are prepared to respect the basic rules of the post-1945 order.
Alliances and treaties already in place
Security arrangements for Greenland are not improvised, nor are they purely political statements. In 1951, Washington and Copenhagen concluded the Defense of Greenland Agreement, enabling US forces to operate in Greenland for the benefit of NATO’s collective defense while affirming Danish sovereignty. That framework remains in force alongside the North Atlantic Treaty, which defines the alliance’s geographic scope.
The United States has maintained a continuous presence at the former Thule Air Base – renamed Pituffik Space Base in April 2023, reflecting the US Space Force mission and the site’s Greenlandic name. The change underscored both strategic relevance and cultural recognition of the local community, illustrating how defense arrangements and Indigenous rights are increasingly discussed in the same breath in Arctic policymaking.
The EU’s mutual-assistance clause adds another layer: Article 42(7) of the Treaty on European Union obliges all EU member states to aid a member suffering armed aggression on its territory, in a manner consistent with NATO commitments for those states that are allies. While the EU is not a military alliance like NATO, the clause is a formal solidarity instrument Denmark could invoke if necessary, turning any attack on Greenland into a test case for both European and transatlantic security guarantees.
Old ambitions, new Arctic realities
The United States has eyed Greenland before. In 1946, the Truman administration secretly offered Denmark $100 million in gold for the island; Copenhagen declined. The episode resurfaced in public memory when Trump floated a purchase in 2019, prompting Danish Prime Minister Mette Frederiksen to call the idea “absurd” and the White House to cancel a planned state visit. The latest flare‑up revives that historical throughline in a far more charged geopolitical moment, when Arctic shipping lanes, seabed resources and missile‑warning radars all sit at the center of national-security planning.
Today’s stakes are larger than maps and minerals. Greenland sits astride transpolar routes and early‑warning arcs central to NATO and US homeland defense. Yet Arctic governance still runs through institutions designed to keep the region’s competition bounded. Work within the Arctic Council – where the Kingdom of Denmark participates with Greenland and the Faroe Islands – has continued on a limited basis since 2022 without Russia after Moscow’s invasion of Ukraine, emphasizing civilian cooperation on climate and Indigenous issues and deliberately excluding hard security.
A cultural protest with legal teeth
What began as a tongue‑in‑cheek retail item is now a visible shorthand for a precise legal and diplomatic position. For Danish and Greenlandic officials, the caps help translate dense treaty clauses into something graspable on the street. The message aligns with three uncontested facts:
- Greenland’s constitutional status and any move toward independence are determined by Greenlanders under the 2009 Self‑Government Act and with both Greenlandic and Danish parliamentary consent.
- NATO’s treaty area covers Greenland as an island under Danish jurisdiction north of the Tropic of Cancer; aggression there would engage alliance consultations and, if warranted, collective defense.
- The UN Charter forbids threatening or using force to change borders or seize territory, rendering annexation by coercion unlawful.
Back at Tonnesen’s shop, the production line is catching up. The slogan that once seemed like a joke now reads as a boundary line – red‑stitched and unambiguous – drawn by citizens of two Arctic polities whose status is anchored in law. As of January 20, 2026, Denmark and Greenland say their sovereignty arrangements are unchanged, NATO’s treaty guarantees remain in force, and a new batch of “Make America Go Away” caps is on order.
