Donald Trump has discussed with advisers the possibility of withdrawing some
U.S. troops from Europe, though no decision has been made and no formal planning
has begun, a senior White House official said. The talks reflect worsening
relations with NATO, amid disputes over the Strait of Hormuz and Greenland. The
U.S. maintains over 80,000 troops in Europe. Reuters reports tensions remain
high despite a recent White House visit by Mark Rutte.
