Here’s what happened the last three times the U.S. tried to acquire Greenland.

It was a contentious, aggressive telephone call, five days before the inauguration of President Donald Trump on Jan. 20.

From the Reconstruction era to the Cold War, multiple administrations have tried (and failed) to acquire the Arctic island. Here’s why Greenland has always remained out of reach—and why it always mattered so much.

President Trump had a “firm” phone conversation with Denmark’s prime minister last week to convey his serious intentions of acquiring Greenland, according to a report citing officials privy to the talk.

President Donald Trump told Denmark ’s prime minister he is serious about taking over Greenland in a “fiery” phone call last week, the Financial Times reports. Trump and Mette Frederiksen spoke on the phone for 45 minutes last week after the president said he wanted the US to take Greenland, despite officials repeatedly saying it’s not for sale.

The top European Union military official, Robert Brieger, said it would make sense to station troops from EU countries in Greenland, according to an interview with Germany's Welt am Sonntag published on Saturday,

Denmark agreed on Friday to discuss the Arctic region with Washington, Foreign Minister Lars Lokke Rasmussen said, after his first phone call with the top diplomat of the administration of President Donald Trump,

Taking Greenland through force or coercion would not just be a bad deal for the United States—it could become a legacy-defining unforced error for the Trump administration.

President-elect Donald Trump’s attempts to secure Greenland are rooted in legitimate national security concerns—but to make any progress towards this goal, he must first win the support of its people.

Trump has said Denmark would be committing a 'very unfriendly act' if it did not allow the US to take over Greenland. What's behind the US President's increasingly aggressive bid for a snow-covered island?

Danish Foreign Minister Lars Løkke Rasmussen agreed with US Secretary of State Marco Rubio to discuss the issue of Greenland at a later time. This was the result of their 20-minute conversation, The Guardian reports.
