The sheer unpredictability of Trump's caprice, and his faith in his quixotic charisma, made it hard for diplomats to operate. It would often taken feverish consultations with Trump's senior aides, including some in the Pentagon, before a plan - such as a premature withdrawal of 2,500 US troops from Afghanistan - could be finessed.
