The reaction against the Vietnam War, by students and domestic groups inside america was a unique challenge to the intelligence community. I have read about the SDS, the Weathermen Underground and heard about the events that happened but I was skeptical that it could have been orchestrated by China or Vietnamese authorities.
Frank Rafalko is honest enough to admit that they were very close but they just didn't find anything and I think this only makes things more interesting. What really did happen, will we ever find out? Were naive students really capable of organising a terrorist campaign inside the USA without external help?
Rafalko was there doing the work and he gives his own perceptions.
