This is a fantastic documentary. The contribution of academics, former world leaders and former heads and members of various organisations such as the CIA give this documentary a level of detail and information that makes it fascinating. Yes, it does have an end game about how nuclear weapons should be gotten rid of, however this is only addressed in a propaganda like manner in the last 10 minutes. The rest of the film is spent looking at the risks of a nuclear fall out. Using the 'nuclear sword of Damacles' quote by JFK it looks at the three great threats of nuclear war; a mistake, war, and terrorism. It is fast passed and intriguing, using footage of nuclear weapons inter shot with commentary by the a fore mentioned experts and people involved with nuclear weapons. It doesn't insult the intelligence of those watching, explaining elements of nuclear war if it is needed, but not in a patronising manner, but with a level of respect for those watching which seems to be rare in documentaries, especially American ones. All in all, I would heartily recommend this DVD to anyone who is interested in the history of the nuclear threat.
