President Trump’s talk of taking Greenland isn’t a joke, that much is now clear. His ambition to "conquer" the autonomous Danish territory is a direct challenge to the EU, Nato, and the post-Cold War security order - so what should Europe do?

Roland chats to Rachel Ellehuus, head of British defence and security think tank RUSI and formerly a senior US official in Nato and the Pentagon. She explains why Greenland matters far more than most people realise: from missile defence and Arctic dominance to critical minerals and great-power competition.

They also discuss why Trump’s threats should be taken seriously, how Denmark and Greenland are responding behind the scenes, and why this moment is critical for Europe if it wants to protect its values and way of life.
