Where Kennedy differed from Castro, and also from Khrushchev, was in his sense of detached irony, which also had a lot to do with his long illness. He was forever questioning conventional wisdom. Castro was narcissistic and self-absorbed: all that mattered were his own actions and his own will. Khrushchev reduced world affairs to crude calculations of political power. Kennedy had a knack for looking at problems through the eyes of his adversaries. His “capacity for projecting himself into other people’s shoes” was at once his curse and his strength.
