NATO’s top military commander said Thursday the alliance was ready, if asked, to plan a mission to protect the Arctic, after US president Donald Trump announced a framework deal he said satisfied his demands on Greenland.

‘We’ve done no planning yet. We have not received political guidance to move out,’ US General Alexus Grynkewich, NATO’s supreme commander for Europe, said after a meeting of alliance top brass.

‘We’re doing some thinking about how we would organise for it — no planning has started yet, but we’re ready.’

Launching a NATO mission in the Arctic has been floated as a possible solution after Trump used the perceived threat from Russia and China to justify his desire to take Greenland.

Meanwhile, the United States and Denmark will renegotiate a 1951 defence pact on Greenland, a source familiar with talks between Trump and NATO chief Mark Rutte said Thursday.

The source said that European allies would also step up Arctic security, but insisted that placing American bases on Greenland under US sovereignty had not been discussed.

‘The 1951 agreement will get renegotiated,’ the source said.

The defence agreement, updated in 2004, already gives Washington freedom to ramp up its troop deployments, provided it informs the authorities in Denmark and Greenland in advance.

The US currently has one base on Greenland — the Pituffik Space Base on the northwest of the island that constitutes a crucial link in the US missile defence system.

Trump on Wednesday announced a framework deal after talks with Rutte at the World Economic Forum in Davos, but the details of the purported agreement remained vague.

Rutte said on Thursday one ‘work stream’ to emerge from the meeting was ‘that we ensure that the Chinese and the Russians will not gain access to the Greenland economy’ or militarily.

Trump’s threats to take Greenland have rocked the transatlantic alliance and plunged NATO into its biggest crisis in decades.

Some European nations have pushed for NATO to launch a mission in the Arctic to try to shore up security in the region after Trump used it to justify his desire for Greenland.

Trump warned Thursday of major reprisals if European countries dumped key holdings of US Treasury bonds to pressure Washington, as temperatures fluctuated over the future of Greenland.

‘If that would happen, there would be a big retaliation on our part, and we have all the cards,’ Trump said on Fox Business Network’s ‘Mornings with Maria.’

But he acknowledged that European countries had notable holdings of US Treasury securities.

Trump’s remarks came after tensions flared over the fate of the autonomous Danish territory of Greenland — which the US leader covets.

The American president has repeatedly said that the United States, the key force in NATO, deserves Greenland as it would be forced to defend the island against Russia or China. Neither of those countries holds any claim to the territory.

More recently, Trump’s threats to impose tariffs on European countries for not going along with his demand to get Greenland rattled global markets.

But at the World Economic Forum in Davos, Switzerland, Trump on Wednesday backed down on threats to seize Greenland by force from ally Denmark, and lifted the threat of sanctions against European nations.

For now, some observers believe that Europe has economic leverage in the situation, as European NATO countries hold more than $2 trillion of US Treasuries.

If Canada were included, the figure rises to around $3 trillion, according to US government data.

On Wednesday, Swedish pension fund Alecta said it sold the bulk of its US Treasury bonds over the past year, citing what it called the unpredictability of the current administration and growing US debt.

This made it the second large Nordic fund to make such a decision public, with Danish fund Akademiker Pension announcing Tuesday that it was selling its US Treasuries.

But the Danish fund said its decision was unrelated to the situation over Greenland, linking it instead to poor US government finances.

US treasury secretary Scott Bessent this week rejected the idea that Europeans were targeting US debt in retaliation for Washington’s designs on Greenland.
