In a report released on Wednesday, the Danish Defense Intelligence Service said that shifts in American policy are creating new concerns for the country's security.

It cited Trump's use of reciprocal tariffs against American allies and its efforts in the Arctic to seize control of Greenland, a semi-autonomous territory of Denmark, The New York Times reports.

'The United States uses economic power, including threats of high tariffs, to enforce its will and no longer rules out the use of military force, even against allies,' the report read, in a thinly-veiled swipe at Trump's threat to use force to wrest control of Greenland from Denmark.

The annual report also argued that the Trump administration's growing focus on competition with China 'creates uncertainty about its role as the primary guarantor of security in Europe.'

'The USA's changed policy places great demand on armaments and cooperation between European countries to strengthen deterrence against Russia,' it notes, according to Politico.

In a worst-case scenario, the Danish intelligence services predict that NATO allies could find themselves in a situation where both China and Russia are ready to fight their own regional wars in the Taiwan Strait and the Baltic Sea, respectively.

The report comes just one week after the Trump administration released its own national security report, calling on European nations to take 'primary responsibility' for their own defense.

It went on to warn that Europe is facing the 'stark prospect of civilizational erasure,' for which, the report said, the US should be 'cultivating resistance' across Europe by supporting right-wing political parties opposed to migration.

That shift created a 'dilemma' for Europe, according to Thomas Ahrenkiel, the head of the Danish Defense Intelligence Service, though he emphasized in public remarks that the US remains Denmark's 'closest partner and ally.'
