Dr. Strangelove: Documentary?

Fred Kaplan:

The result was wildly iconoclastic: released at the height of the cold war, not long after the Cuban missile crisis, before the escalation in Vietnam, “Dr. Strangelove” dared to suggest – with yucks! – that our top generals might be bonkers and that our well-designed system for preserving the peace was in fact a doomsday machine.
What few people knew, at the time and since, was just how accurate this film was. Its premise, plotline, some of the dialogue, even its wildest characters eerily resembled the policies, debates and military leaders of the day. The audience had almost no way of detecting these similiarities:Nearly everything about the bomb was shrouded in secrecy back then. There was no Freedom of Information Act and little investigative reporting on the subject. It was easy to laugh off “Dr. Strangelove” as a comic book.
