Tensions are escalating between the United States and Europe after President Trump threatened to impose tariffs on eight European allies that oppose his push to take over Greenland, a semiautonomous territory of Denmark. On Sunday, Trump sent a text message to Norway’s prime minister, writing, “Considering your Country decided not to give me the Nobel Peace Prize for having stopped 8 Wars PLUS, I no longer feel an obligation to think purely of Peace.” Trump went on to write, “The World is not secure unless we have Complete and Total Control of Greenland.” In a post overnight, Trump also criticized Britain for giving the Chagos Islands back to Mauritius after nearly six decades of British rule.

Over the weekend, thousands took part in protests in Greenland and Denmark. European leaders denounced Trump’s threats and are weighing cutting off U.S. companies to the EU market — a move known as the EU’s trade bazooka. U.K. Foreign Secretary Yvette Cooper spoke on Monday.

Yvette Cooper: “As the prime minister said this morning, the future of Greenland is for the Greenlanders and for the Danes alone. Greenland is a part of the Kingdom of Denmark, and those principles around sovereignty are crucial. It’s also why we have made very clear that the use of tariffs and threats against allies in this way is completely wrong and counterproductive.”

President Trump is heading today to the World Economic Forum in Davos. The Washington Post reports the elite gathering has been turned into an emergency diplomatic summit this year due to Trump’s threats to take Greenland.
