“Time was on the side of the enemy, and we were in a position of not being able to win, not being able to get out…only being able to lash out…And so the war went on, tearing at this country; a sense of numbness seemed to replace an earlier anger. There was, Americans were finding, no light at the end of the tunnel, only greater darkness.”

The late David Halberstam, writing about Vietnam in The Best and the Brightest, 1972.
