Denmark is potentially on the brink of legal action due to an agreement with the US that bestows significant operational powers on American forces within Danish territory. Signed during the Biden administration and ratified by the Danish parliament in 2023, the deal allows the US unhindered access to key airbases and broad authority over Danish civilians. The legality of this agreement is now under scrutiny, particularly due to its implications on Danish constitutional sovereignty as highlighted by independent MP Theresa Scavenius's intention to challenge it in court.

The controversy surrounding this agreement is exacerbated by historical tensions, notably Donald Trump's past proposals to purchase Greenland, a territory that remains under Danish sovereignty. Trump's public threats and the subsequent European military deployment to Greenland have strained relations between Denmark and its allies, thereby complicating diplomatic discussions. The potential lawsuit may not only challenge the legal foundations of the US-Danish agreement but could also impact ongoing negotiations with the US regarding Greenland's status and future relations.

Scavenius argues that the Danish constitution requires any transfer of sovereignty to international entities to undergo a constitutional amendment, necessitating extraordinary parliamentary support. The unfolding legal battle could have significant ramifications for Danish sovereignty, US-Danish relations, and the geopolitical landscape surrounding Greenland, an area of strategic interest for both nations, particularly amidst rising tensions in the Arctic region.
