Key Evidence
Greenland's Prime Minister Jens-Frederik Nielsen publicly stated the need for preparation against a possible U.S. Military invasion amid Trump's takeover threats.
Multiple independent news organizations reported this statement on or around January 20, 2026.
The Prime Minister emphasized the scenario remains unlikely but possible, underscoring a cautious approach.
What the Evidence Shows
In January 2026, numerous reputable news outlets including Express.co.uk, Metro.co.uk, The Express US edition, Latin Times, The Mirror, Australian Financial Review, Yahoo Finance (Bloomberg), Financial Post, and Hindustan Times consistently reported that Greenland's Prime Minister Jens-Frederik Nielsen advised the island's population and authorities to prepare for a potential military invasion. This advisory was framed in the context of escalating tensions due to repeated takeover threats by U.S. President Donald Trump.
While the Prime Minister stressed that a military conflict was unlikely, he acknowledged it could not be completely ruled out, prompting precautionary measures. The consistency across these sources confirms the factual basis of the claim. The reports also clarify that the warning is precautionary rather than an indication of imminent invasion.
