Denmark deploys additional troops to Greenland after President Donald Trump claims the island is not secure from Russia or China.

The president is feeling "emboldened" by his strike on Venezuela, which ousted leader Nicolás Maduro, a White House official said.

"We are currently being caught in broader political conflicts driven by opposition to Donald Trump," Naleraq party leader Pele Broberg told ABC News.

Denmark’s Joint Arctic Command is expanding military exercises in Greenland to potentially run year-round, a Greenlandic newspaper reported, as the US ramps up pressure over control of the Arctic island.

U.S., Danish and Greenlandic officials have met face to face to discuss President Donald Trump’s ambitions to take control of Greenland, a semiautonomous territory of Denmark.

Pentagon officials plan for all sorts of military contingencies, but they have not yet been asked to draw up an invasion of Greenland or the aftermath of such an operation.

In Trump’s message, sent Jan. 18, he said, "Why (does Denmark) have a ‘right of ownership’ anyway? There are no written documents, it’s only that a boat landed there hundreds of years ago, but we had boats landing there, also."

Trump on Wednesday is set to address the World Economic Forum in the Swiss Alps, where his ambitions to wrest control of Greenland from NATO ally Denmark could tear relations with European allies and overshadow his original plan to use his appearance at the gathering of global elites to address affordability issues back home.
