Propaganda writes: "This film is interesting only in the fact that it is an odd relic of anti-Cold War propaganda; a pacifist film touting a suicidal philosophy of disarmament. Its particularly ironic that the smugness of the film's creators is now quite laughable in the hindsight of history. Despite all the dire predictions this film makes, thirty years later the U.S. would ultimately win the Cold War against the Soviet Union... and without a nuclear shot being fired in anger."
Respectfully, I disagree. The film does not tout disarmament. The theme of the film, which runs throughout, is that the machines 'are too fast', the military systems have the great potential to fail, and that our mutual distrust of what we don't understand (our enemies) which lead us to create situations of conflict with each other, which end in needless, tragic, destruction. This is a theme that runs throughout the events of history, that is what makes Fail-Safe timeless.
