The Vietnam War came to an end in 1975. But another battle is brewing — as Obama has launched a decade of commemoration — and that is over how the war is to be remembered. Was it a noble cause that was poorly executed? Or was the war itself immoral? And when we look at the toll of the war, who should be included and who forgotten? Historian John Marciano argues that how the American war in Vietnam is remembered has everything to do with the present and the shaping of public support for American war-making.
