Trump calls off tariff threats over Greenland, agrees to NATO deal

President Trump has called off his Greenland-related tariff threats against European allies. The president had threatened tariffs in his bid to gain ownership of Greenland. But he called off the threat after agreeing with NATO on a future Arctic security deal. One possibility is the U-S building more military bases on the Danish island. His tariff threats had sparked a sharp drop in the financial markets, and angered European leaders who feared the collapse of NATO.
