President Trump's pursuit of Greenland threatens to reignite a trade war with Europe and upend the NATO alliance.

Eight nations targeted by new White House tariffs have hit back at President Donald Trump, accusing the U.S. of threatening to undermine transatlantic relationships and risking a "dangerous downward spiral."

President Donald Trump announced that the NATO countries who have sent small contingents of troops to Greenland will be charged a 10% tariff on all goods.

In the aftermath of the U.S. military operation in Venezuela that led to the capture of the South American country’s president, Nicolás Maduro, Trump has doubled down on his desire to annex Greenland, an autonomous territory within the Kingdom of Denmark. He has repeatedly claimed that the U.S. needs Greenland for “national security” reasons.

President Donald Trump ’s pledges to provoke a sweeping tariff fight with Europe to get his way in taking control of Greenland has left many of America’s closest allies warning of a rupture with Washington that would shatter the NATO alliance that had once seemed unshakable.

The U.S. president isn’t ruling out aggressive steps to take control of Greenland, but he struck a more conciliatory tone on Tuesday.

British Prime Minister Keir Starmer has publicly broken ranks with U.S. President Donald Trump over his renewed pressure campaign for the annexation of Greenland. Trump threatened to impose a 25% tariff on the U.K. and other European allies until Denmark relents and sells the territory of Greenland—a move Starmer has labeled “completely wrong.”
