It seems to me hippies who see the biggest threats as internal are always a product of a secure environment. I suspect such attitudes don't thrive in places with war on the ground. America has never had a major invasion in terms of amount of land invaded. We seem particularly prone to this idea that war happens elsewhere and is not a real and serious threat.
Regardless, my comment wasn't intended to be judgemental, I apologize if it came off that way. I just wanted to point out the similarities between effective cult leadership and military indoctrination, but should have been more clear that I was speaking more academically.
