A group of European countries, led by Britain and Germany, is discussing plans to boost their military presence in Greenland to show U.S. President Donald Trump that the continent is serious about Arctic security,

"I mean, NATO would have an obligation to defend Greenland. And so query whether we would be at war with Europe, with England, with France," Sen. Chris Murphy said.

As tensions rise over Greenland, a former Nato deputy warns of a future where Europe might stand alone, questioning the U.S.'s nuclear commitment.

The White House has kept all options for acquiring Greenland on the table, refusing to rule out military action.

Trump has said the U.S. "needs" Greenland for security reasons, amid the specter of force to take control of the vast Arctic island.

Germany will propose setting up a joint NATO mission to monitor and protect security interests in the Arctic region in a bid to ease tensions with the US over its threats to annex Greenland, according to two people familiar with the government’s thinking.

Britain's Transport secretary characterized the security talks as "business as usual" rather than a direct response to Trump.
