Russia is watching with glee as U.S. President Donald Trump's drive to acquire Greenland widens splits with Europe even though his moves could have serious security ramifications for Moscow, which covets its own presence in the Arctic.

It’s been a long-standing Kremlin strategy to drive a permanent wedge between the United States and Europe, dividing and weakening its traditional adversaries in the West.

Ahead of the Davos forum in Switzerland, Trump shares a message apparently from the French president that says: "I do not understand what you are doing on Greenland."

That contingent believes that Trump’s obsession with acquiring Greenland — and the shaky and varying reasons underpinning it — have diverted attention from Ukraine and even redirected resources to Greenland. That all complicates European efforts to maintain a strong, united front as the U.S. is pushing hard for a peace deal to end the war.
