This was a very interesting movie. It not only gives the historical development of atomic/thermonuclear weaponry, but presents it all within the context of the Arms Race and the Cold War. As I grew up nearing the end of the Cold War, this movie helped me gain some perspective on the cultural context of my youth. I had told my 25 year-old coworker about this movie and he said, "Cold War? What's that??" It's a very fascinating movie on many levels. There are two or three other movies in this series, but this is the place to start.Grace and peace,Jeffrey
