COPENHAGEN, July 8 — The shift is unmistakable. Mette Frederiksen, the Danish prime minister who famously dismissed a US offer to buy Greenland as “absurd” in 2019, has spent the last year repositioning her nation as a hardened, ready-for-anything NATO ally. The trend underneath isn’t just about Arctic real estate; it’s about a fundamental recalibration of what European defence looks like when a superpower starts eyeing your territory.
Frederiksen took office on June 27, 2019, as the youngest prime minister in Danish history, at age 41. She came from a solid track record in domestic portfolios — Minister of Employment from 2011 to 2014, then Minister of Justice from 2014 to 2016.
But her premiership was immediately marked by a foreign policy firestorm when President Donald Trump floated the idea of purchasing Greenland. Her response was blunt: the idea was “absurd.” The diplomatic row that followed was sharp and very public. Fast forward to February 7, 2025, and the tone had changed entirely.
Frederiksen stated plainly that Denmark is ready to defend “every inch of NATO,” including the Danish kingdom. That’s not just rhetoric.
The kingdom includes Greenland, the very territory Trump had sought. Watch this space: the prime minister is no longer dismissing US interest; she is drawing a line in the Arctic ice and backing it up with spending.
Defence spending and the 2% target
Frederiksen has prioritized defence spending, pledging to reach NATO’s 2% GDP target by 2025. That commitment is a concrete shift from years of under-investment by many European allies. For Denmark, a country that has historically been a cautious spender on hard power, this is a significant pivot.
The pledge aligns with the broader NATO push, but for Frederiksen, it carries the specific weight of needing to credibly defend a vast, strategically vital territory in the High North. What’s changing is the speed.
The 2025 deadline was an ambitious one, and it signals that Copenhagen sees the security environment as urgent. The prime minister is effectively saying that the era of relying on US goodwill to guarantee Greenland’s security is over; Denmark must be a contributor, not just a consumer, of alliance defence.
Climate policy: the other front
Frederiksen’s government hasn’t abandoned its progressive domestic agenda. The same administration that is beefing up the military is also aiming for a 70% reduction in greenhouse gas emissions by 2030. That is one of the most aggressive national climate targets in the world.
It’s a dual-track approach that is rare among Western leaders: invest heavily in both the green transition and traditional defence. The tension is real.
Defence spending and climate action both require enormous public investment. But Frederiksen seems to be betting that the two are not mutually exclusive. If anything, the logic runs that a greener Denmark is a more energy-independent Denmark, and that strengthens national security.
The trend underneath is a prime minister who refuses to be boxed into a single identity — she is the climate leader and the NATO hawk, simultaneously.
What to watch next
The question now is whether Frederiksen’s twin commitments — to NATO’s 2% target and to the 70% emissions cut — can survive the political and economic pressures of 2026. The US administration under President Trump has shown no signs of dropping its interest in Greenland. If anything, the Arctic is heating up, both literally and geopolitically.
Frederiksen has staked her legacy on being the prime minister who modernised Denmark for a tougher world. She is no longer the young leader who laughed off a US president’s offer.
She is now the one who says Denmark will defend every inch of its kingdom — and is spending to prove it. Watch this space: the next move may not come from Copenhagen, but from Washington. And Frederiksen is ready.
