It was an insult so outrageous that it has probably alienated the British and other European publics more than any previous Trump attack. Adding insult to injury, the president falsely claimed on Fox News that the NATO allies “stayed … off the front lines” in Afghanistan. Although the U.S. military took the highest losses, many smaller NATO members came close to or even exceeded the proportion of dead to their population. (Yet, even as he denigrated the Danish dead, Trump was demanding that Copenhagen, long one of America’s closest allies, turn over Greenland to the United States.) With his sneers at foreign troops who sacrificed for America, Trump has done more than alienate America’s closest allies.
