The wife of Donald Trump’s homeland security adviser Stephen Miller has sparked a diplomatic backlash after posting a map of Greenland coloured in the stars and stripes of the United States, prompting an official response from Denmark, as reported by The WP Times citing a post on X. Katie Miller, a conservative political commentator and Trump ally, shared the image on X, showing Greenland entirely overlaid in the red, white and blue of the US flag. Beneath the image she added a single-word caption: “Soon.”
The post was widely interpreted as a reference to Trump’s long-running interest in Greenland, the strategically important Arctic territory that remains part of Denmark while operating with a high degree of political autonomy.
The US political website The Daily Beast reported that Miller’s post appeared shortly after American media carried reports of a successful US operation against Venezuelan leader Nicolás Maduro — a coincidence that fuelled speculation that the image was intended as a symbolic show of US geopolitical reach rather than a literal policy statement.
Regardless of intent, the reaction from Copenhagen was swift.
Denmark’s ambassador to the United States, Jesper Møller Sørensen, issued a public rebuke on X, stressing that Greenland is already a NATO territory and warning against any suggestion that its status is open to challenge.
“Just a friendly reminder to the United States and the Kingdom of Denmark: we are close allies and must continue to act as such,” Sørensen wrote. “US security is also Greenland’s and Denmark’s security. Greenland is already part of NATO. The Kingdom of Denmark and the United States work together to ensure Arctic security. And yes, we expect full respect for the territorial integrity of the Kingdom of Denmark.”
The unusually direct tone of the ambassador’s message reflects the sensitivity of the issue in Copenhagen, where even symbolic gestures about Greenland are closely watched.
Why Greenland matters to Washington
Greenland occupies a uniquely strategic position in the Arctic, sitting between North America and Europe along key air and sea routes. The US already operates Pituffik Space Base (formerly Thule Air Base) in north-west Greenland, a critical hub for missile warning, space surveillance and Arctic operations.
As melting ice opens new shipping lanes and increases access to rare-earth minerals, the island’s geopolitical value has risen sharply. Washington sees Greenland as central to countering Russian and Chinese influence in the High North.
That is the context in which Donald Trump first stunned allies in 2019 by publicly floating the idea of buying Greenland — a proposal that Denmark flatly rejected, calling it “absurd”.
After returning to the White House in 2025, Trump revived the theme, arguing that US control over Greenland would be essential for American and NATO security in the Arctic.
In August 2025, Danish prime minister Mette Frederiksen accused figures close to Trump of attempting to interfere in Greenlandic political processes, warning that pressure from Washington was becoming increasingly overt. Two months later, she said the US president appeared to have cooled on the issue — but that the risk of it resurfacing remained.
Since then, Denmark has reinforced its military presence on the island and increased surveillance and patrols around key infrastructure.
In December 2025, Trump appointed Louisiana governor Jeff Landry as his special representative for Greenland, a move widely interpreted in Copenhagen as a signal that Washington intended to keep the territory firmly on its strategic agenda.
A symbolic act with real diplomatic consequences
Katie Miller holds no official government position, but her proximity to the White House gives her public statements political weight. In a highly charged international environment, even a single word and an image can trigger diplomatic friction. By colouring Greenland in US national colours and writing “Soon”, she touched directly on one of the most sensitive territorial questions in transatlantic relations. For Denmark, which governs Greenland in partnership with its own elected government in Nuuk, the implication that the island could somehow be absorbed into the United States — even jokingly — crosses a red line. For Washington, the episode underlines how informal online posts can complicate formal diplomacy, particularly when they appear to echo the ambitions of a sitting president. What was posted as a provocation on social media has now become a reminder of how fragile Arctic geopolitics has become in the second Trump era.
Background: Trump, Greenland and the events leading up to the post
Greenland is an autonomous territory within the Kingdom of Denmark, with its own government and parliament, while Copenhagen controls foreign affairs and defence. Through Denmark, Greenland is also part of NATO. The United States has maintained a permanent military presence on the island since the Second World War. Its Pituffik Space Base in north-west Greenland plays a key role in missile warning, satellite tracking and Arctic defence.
Donald Trump first raised the idea of the United States acquiring Greenland in 2019 during his first term as president. Denmark rejected the proposal, saying the territory was not for sale. The issue nevertheless highlighted Washington’s growing focus on the Arctic as a strategic region.
After Trump returned to office in 2025, he again described Greenland as vital to US national security. Senior figures in his circle began to speak more openly about the need for stronger American influence over the island. In August 2025, Danish prime minister Mette Frederiksen said that people close to Trump were attempting to influence political processes in Greenland. She warned that Denmark was facing increasing pressure over the future of the territory.
Denmark subsequently increased military patrols and surveillance around Greenland, citing the need to protect its territory and Arctic infrastructure.
In December 2025, Trump appointed Louisiana governor Jeff Landry as special envoy for Greenland, a move that was widely interpreted as a sign that Washington intended to keep the issue high on its strategic agenda. These developments formed the political background against which Katie Miller later posted the image of Greenland in US flag colours.
