Exactly forty-five years ago, on April 29, 1975, the last helicopter lifted off the roof of the American embassy in Saigon, taking the last Marines, the U.S. Ambassador, and the U.S. flag to the command ship Blue Ridge waiting offshore.  It was the heartbreaking end to a twenty-year war from 1955 to 1975.  As I watched it on television, with rising anger, I kept asking myself why we had sacrificed 58,209 American boys?  It is a bitter irony that, exactly 45 years later, we realized we have now lost more Americans in the last three months from the coronavirus than the twenty years in Vietnam.  Our national sorrow is just beginning . . .
