AMERICA’S HUNGER for Greenland is setting off an explosive row within NATO.  President Donald Trump, infuriated by European allies’ resistance to his effort to annex the autonomous Danish territory, said on January 17th that he would impose 10% tariffs on imports from eight European countries that had sent troops there two days earlier.

Sens. Thom Tillis (R-N.C.) and Lisa Murkowski (R-Alaska) on Saturday slammed President Trump’s new 10 percent tariffs on Denmark and European allies, saying the tariffs will hurt the U.S.
