US President Donald Trump has escalated tensions with Europe by threatening a 25% tariff on multiple countries, including Denmark, Germany, France, and the UK, until Greenland is sold to the United States. In a post on Truth Social, Trump announced a 10% tariff beginning February 1 on goods from Denmark, Norway, Sweden, France, Germany, the UK, the Netherlands, and Finland. He warned that the rate would rise to 25% on June 1 if no agreement is reached. “This Tariff will be due and payable until such time as a Deal is reached for the Complete and Total purchase of Greenland,” Trump said. The president’s longstanding desire to acquire Greenland intensified after a US raid captured Venezuelan President Nicolás Maduro in early January. Trump cited national security concerns, though these claims were challenged by Denmark and other allies. NATO forces had recently increased their presence in Greenland in response to Trump’s threats, aiming to enhance Arctic security. Denmark’s foreign minister, Lars Løkke Rasmussen, described the military presence as constructive, emphasizing it posed no threat. Rasmus Jarlov, chair of Denmark’s defense committee, responded more strongly: “The answer from Denmark and Greenland is final: We will never hand over Greenland. We pray that our true allies will stand with us because we are going to need it.” European leaders condemned Trump’s tariff threat. EU Commission President Ursula von der Leyen expressed solidarity with Denmark and Greenland, warning that tariffs risked undermining transatlantic relations. UK Prime Minister Keir Starmer echoed that Greenland’s future is for the Greenlanders and Denmark to decide, calling Trump’s tariffs “completely wrong.” French President Emmanuel Macron drew parallels between Trump’s Greenland threats and Putin’s aggression in Ukraine, asserting that intimidation would not influence France, Denmark, or Greenland. Leaders from Sweden, Norway, and Finland also rejected Trump’s coercion. Germany’s leadership opted for a more measured response, though reports suggested a potential World Cup boycott as leverage against Trump. Protests erupted in Greenland and Denmark against Trump’s bid to acquire the island, while US politicians, including Senator Thom Tillis, criticized the tariff strategy as harmful to America and advantageous to adversaries like Russia and China. Trump, who has frequently used tariffs as leverage in trade negotiations, stated he was open to negotiating with Denmark and other targeted nations. However, his unpredictable approach has raised concerns about damaging global trade and the US economy. Current tariffs have pushed the average effective US tariff rate to 16.8%, the highest since 1935. Greenland’s Prime Minister and European officials have stressed that Arctic security is a shared NATO concern. While fewer than one in five Americans support Trump’s Greenland acquisition, only 4% favor using military force. The US Supreme Court is currently reviewing the legality of several of Trump’s tariffs, with a ruling expected soon. Trump’s latest actions, following heightened US involvement in Venezuela, signal a volatile phase in international relations. European allies have united in defense of Greenland, warning against coercion and potential economic escalation, while protests across Denmark and Greenland highlight local opposition to the US president’s plans. The unfolding dispute over Greenland underscores rising tensions in transatlantic relations and raises questions about the stability of global trade and diplomacy in the Trump era.
