Former US President Donald Trump announced on January 16, 2026, that he might impose tariffs on countries that do not support the United States' ambition to acquire Greenland. Speaking at a White House health roundtable, Trump reiterated that Greenland is vital for US national security due to its strategic location and significant mineral resources. The proposal for the US to take control of Greenland, an autonomous territory within the Kingdom of Denmark, has been consistently rejected by both Denmark and Greenlandic leaders, who have affirmed that the island is not for sale. Trump's latest threat has been met with strong criticism, raising concerns about potential trade wars and further strained relations with European allies. In response to the escalating tensions, a bipartisan delegation of 11 US lawmakers visited Copenhagen on the same day to engage with Danish and Greenlandic leaders. The delegation aimed to "lower the temperature" and offer assurances of congressional support for the long-standing alliance. Simultaneously, several European nations, at Denmark's request, have deployed small numbers of military personnel to Greenland, signaling solidarity and a clear message against any forceful takeover attempts. This development underscores the geopolitical significance of the Arctic region and the diplomatic challenges arising from Trump's persistent pursuit of the territory.
