The shortest commentary of the day belonged to Henry Kissinger, the famed diplomat, who spoke of McCain’s grace in leading the effort to normalize relations with Vietnam — two decades after being dehumanized there during his five-and-a-half-year stay at the Hanoi Hilton. Noting the “turmoil and civic unrest” that greeted McCain when he finally returned home, Kissinger said the young man nonetheless pursued the ideals of “compassion,” “liberty” and “decency” that defined his nation. “The world will be lonelier without John McCain, his faith in America and his instinctive sense of moral duty,” Kissinger said. “None of us will ever forget how even in his parting, John has bestowed on us a much-needed moment of unity and renewed faith in the possibilities of America.”
