U.N. Secretary-General Antonio Guterres and U.S. President Donald Trump could not be more different in background, temperament, experience and leadership style. Trump is brash, loud, vulgar, an amateur outsider and the ultimate disrupter, used to bossing everyone else, who does not do sensitivity. Guterres is courteous, sophisticated, cultured, professional, a global insider and the ultimate conciliator who persuades colleagues to follow his lead.

Yet in some calculations, the U.N. system contributes more to the U.S. economy than it gets from Washington.
