Joseph Dunford, the chairman of the Joint Chiefs of Staff, has a picture of a war memorial in a working-class neighborhood of South Boston, his hometown. Dedicated in 1981, it commemorates local troops killed in Vietnam: 25 young men, several of them friends since childhood, died in combat there. Inscribed at the bottom of the polished black granite surface are the words “If you forget my death, then I died in vain.”
