A social media post by Katie Miller, the wife of White House Deputy Chief of Staff Stephen Miller, has ignited controversy and diplomatic friction after she shared a post on Greenland with the single-word caption “Soon” on X.
The post went viral, accumulating millions of views and drawing criticism on social media, given US President Donald Trump‘s repeated assertions over the past few months about wanting to acquire control over Greenland.
Who is Katie Miller and what was her post about?
Miller has a background in Republican politics and conservative media. She previously served as deputy press secretary at the Department of Homeland Security and later as communications director and press secretary for then–Vice President Mike Pence during the Trump administration’s first term.
Miller’s image, shared shortly after a US military operation in Venezuela that resulted in the capture of Venezuelan leader Nicolas Maduro, depicted the Danish autonomous territory wrapped in the stars and stripes of the United States. The brief caption “Soon” was widely interpreted online as a provocative suggestion of US ambition toward Greenland, a huge Arctic island that is part of the Kingdom of Denmark.

Denmark reacts
Denmark’s official response came swiftly. Jesper Møller Sørensen, Denmark’s ambassador to the US, reposted the image and emphasised in his own message that his country expects “full respect for the territorial integrity” of the Kingdom of Denmark, which includes Greenland.
He highlighted the close alliance between Copenhagen and Washington and noted that Danish and US security interests are linked, especially in the Arctic region. Denmark has also increased its defence spending in the Arctic and North Atlantic to strengthen joint security with NATO partners.
Just a friendly reminder about the US and the Kingdom of Denmark: We are close allies and should continue to work together as such. 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… https://t.co/CboKnlKgJL

.Why is Trump so interested in Greenland?
Greenland holds strategic importance due to its location in the Arctic and its role as part of NATO defence infrastructure. It also has significant natural resources, including minerals critical for high-tech industries. Past comments by US political figures, most prominently from President Donald Trump, who expressed interest in US acquisition of Greenland during his presidency, have already drawn diplomatic sensitivity around the subject.
