As Nation editor Katrina vanden Heuvel recently blogged, Oliver Stone’s “ambitious ten-part documentary series tells the behind-the-scenes stories that have shaped our country and the world as we know it today.”

Narrated by Stone, this new one-hour Showtime series features human events that at the time went dramatically under-reported, but crucially shaped America's unique and complex history. The third episode explores the birth of the American Empire by focusing on Harry Truman’s presidency, his decision to inaugurate the nuclear age, and unsung heroes such as Henry Wallace. Watch it now!
