Since Vietnam, we have come to realize that today's con icts involve more than victory in battle to succeed. We need to win the hearts and minds of the people as well as the re ghts in order to prevail. Ironically, Marines get this. Their legendary courage and tenacity on the battle eld is equally matched by their compassion and engagement with the traumatized civilian population. Marine General Jim Mattis summed it up best when he said, "We can be your worst enemy or your best friend."
