What if Denmark invoked Article 5?

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.

Donald Trump spent a noteworthy chunk of the transition period provoking controversy—and insulting NATO allies—with his proposals for expanding the U.S. Maybe most prominently, he has repeatedly discussed buying Greenland from Denmark,

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.

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.

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

Trump’s concern about the Far North is a legitimate one; he is right to seek a more robust defense against potential Chinese or Russian operations in that region.

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.
