The time has come to stop debating Trump’s intentions and instead focus on how to implement the first expansion of American territory since the Eisenhower administration.

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.

Anders Vistisen, a Danish member of the European Parliament, has told U.S. President Donald Trump to "f*** off" after Trump again expressed interest in purchasing the island of Greenland. Newsweek has contacted the White House and Vistisen for comment via email.

It may be too extreme for Canada or Denmark to view the U.S. as an enemy in the wake of Trump annexation threats, but the line between enmity and amity is currently blurred.

President Trump said Denmark will “come along” on the potential sale of Greenland and emphasized the U.S. and others need the Arctic island to fortify international security in the region.

Whether it was Will Rogers or Tony Soprano, the old advice of "buy land, God's not making any more of it" is good real estate advice, but it's hardly an iron law.

Rich Lowry’s recent editorial suggesting that Trump’s desire to acquire Greenland is a smart real estate move is unworthy of Mr. Lowry, a respected and intelligent conservative.

Greenland Prime Minister Múte Egede tells 'Special Report' that the people of the Arctic island don't want to be Danes or Americans.

NATO boss Mark Rutte said Trump "has been right many times" and played it cool when grilled by members of the European Parliament on the president-elect's Greenland plans.

Finland's foreign minister Elina Valtonen says Greenland is protected by Article 5 of NATO. Any attempt to militarily take over the autonomous Danish territory - as hinted at by US President Trump - would be covered by NATO security provisions.
