President Donald Trump visited Dover Air Force Base in Delaware to view the dignified transfer for six soldiers killed during his war with Iran. It’s delicate for any president to watch the flag-draped transfer cases return home from overseas, a solemn event that honors the dead but shines a spotlight on the human costs of the president’s decisions. The visit presented a potentially fraught moment for Trump, whose comments on military service and sacrifice have prompted some of the biggest controversies of his decade in politics. Ultimately, Trump — wearing a blue suit, red tie and a white USA hat — did not speak Saturday during the transfer.
