Tensions Rise as Trump Heads to Davos
President Donald Trump is set to face European leaders this week at the World Economic Forum in Davos, Switzerland.
The meetings come as tensions grow over Trump’s renewed push for the United States to take control of Greenland.
Over the weekend, Trump imposed 10 percent tariffs on Denmark and several European allies.
The move was meant to pressure them over Greenland’s future.
The tariffs added strain to already fragile transatlantic relations ahead of Trump’s Davos appearance.
Trump also criticized the United Kingdom and shared a text exchange with French President Emmanuel Macron, showing clear frustration over European resistance.
European Leaders Push Back
European officials responded quickly and publicly.
UK Prime Minister Keir Starmer said Greenland’s future must be decided by Greenlanders and Denmark alone.
He called Trump’s rhetoric a step too far.
Macron, speaking on stage in Davos, warned that conflict has become normalized. He said using tariffs to pressure countries over territory is unacceptable and dangerous.
Former Trump chief of staff Mick Mulvaney said Trump’s approach risks isolating the United States. He noted that “America First” is starting to look more like “America Alone.”
Former U.S. Ambassador to Denmark Alan Leventhal said the tariffs have instead unified the European Union.
He warned that European nations are now more likely to resist U.S. pressure together.
NATO and Arctic Security at the Center
Trump and his allies argue Greenland is critical to U.S. national security. They point to growing Russian and Chinese activity in the Arctic.
Former U.S. official Nathan Sales said Greenland matters because it matters to China and Russia. He warned that how the U.S. acts is just as important as its goals.
Russian Foreign Minister Sergey Lavrov called the Greenland dispute a deep crisis for NATO. He said it could lead to an unthinkable clash between alliance members.
Mulvaney said NATO itself could be at risk if the dispute continues. He warned the cost of acquiring Greenland goes far beyond money.
Markets, Diplomacy, and What Comes Next

Trump said he still has good personal relationships with Starmer and Macron.
But he rejected Macron’s invitation to attend a proposed G7 meeting in Paris.
European nations appear to be taking Trump’s words seriously. Troops from Denmark, France, and Sweden arrived in Greenland last week, signaling heightened concern.
Trump has not ruled out military force, though the White House says diplomacy remains the first option.
When asked how far he would go, Trump said, “You’ll find out.”
Why This Matters
This dispute goes beyond Greenland. It tests U.S.–EU trust, NATO unity, and global markets already sensitive to tariffs and security risks.
The Greenland fight has turned Davos into a pressure point, where Trump’s hard-line strategy risks reshaping NATO and long-standing U.S. alliances.
