Peter Kuran really knows how to tell a story! Trinity and Beyond is an excellent documentary that capitalized on much of the declassified Cold War-era nuclear testing footage as well as interviews with the people who worked firsthand in those programs. Neutron Bomb is an excellent addition to T&B and his other films about the history of nuclear weapons development in the US and around the world. They've gone through years of footage and data to tell the stories of these terrible weapons that continue to shape the world we live in. I highly recommend watching both films, as they are time capsules in their footage and interviews about the thinking behind the decisions to develop them and provide insights into their role in the world today.
