World War II may seem ancient in comparison to today and yet its impact remains very much alive. This year, we mark the 70th anniversary of the Allied invasion of Normandy, beginning with the landing on D-Day on June 6, 1944. This Memorial Day, as the U.S. honors members of the Armed Forces who died in service, we can look back at the heroic efforts of those who quite literally helped to save the world seventy years ago.
