Most people who live a long life are fortunate, but Henry Kissinger is more fortunate than most. At 92 he can still make significant interventions on issues of foreign policy. He has outlived not only most of his contemporaries but also some significantly younger critics. And he has survived to see his reputation rebalance itself, in part by living into a foreign-policy era that suggests even his most controversial actions were at least agonizingly considered. Longevity has been good for Henry Kissinger.
