Donald Trump renews his push to acquire Greenland, criticising Denmark’s handling of security concerns and warning of possible tariffs on European allies.

Former US President Donald Trump has once again stirred international debate by reviving his proposal for the United States to acquire Greenland, arguing that Denmark has failed to address growing security challenges in the strategically important Arctic region.

In a post on his social media platform Truth Social, Trump claimed that NATO has repeatedly pressed Denmark to counter what he described as increasing Russian influence in Greenland. According to Trump, Copenhagen’s inability to act decisively has weakened regional security, making US ownership of the territory a strategic necessity.

Trump also escalated his rhetoric by suggesting that economic pressure, including tariffs on European allies, could be considered if Washington’s interests are blocked. His comments come despite firm rejections from Danish and Greenlandic leaders, who have reiterated that the island is not for sale and remains protected under NATO’s security framework.

Greenland, an autonomous territory within the Kingdom of Denmark, has long held geopolitical importance due to its location, natural resources and proximity to Arctic shipping routes.

Trump’s renewed focus on Greenland underscores how the Arctic is becoming a frontline of great-power competition, particularly involving the US, Russia and China. While the proposal remains politically unrealistic, it highlights Washington’s concern over Arctic security and influence. For Europe, the episode serves as a reminder that economic and defence issues are increasingly intertwined, with strategic geography once again shaping global diplomacy.
