Denmark has been in the news lately for all the wrong reasons. President Donald Trump’s unexpected interest in buying Greenland and his subsequent postponement of a planned State Department visit to Copenhagen rankled Danish feathers and left many on both sides of the Atlantic scratching their heads. It is a shame. As important as Greenland is for U.S.-Danish relations, and indeed for the future of the Arctic, America’s alliance with Denmark is about far more than this icy isle.
