Earlier this week, Americans marked Vietnam War Veterans Day to honor the men and women who served in that war.
One of the reasons the war was so controversial was the images that were broadcast across the United States on TV or in newspapers and magazines.
In 2013, the Associated Press collected many of those photos in a book called "
Vietnam: The Real War: A Photographic History by the Associated Press." Here & Now's Robin Young spoke with Santiago Lyon, then-director of photography for the AP, about the collection after its release.
