Undoubtedly, Hubbard saw others as plotting against him and, as a response (to this perceived potting) built Scientology (both doctrine and organization) on the template of a "tight conspiracy" (See 'Bolivar' PL and other writings).
The mind set of suspicion towards others, including his friends and associates, can be seen in his 1950s letters to the FBI, the two key elements of which are paranoia and tall tale telling (lying).
Around 1971, during the unpopular Vietnam war, Hubbard switched from mainly calling his enemies "Communists" to mainly calling them "Nazis." He told Scientologists (in a very well publicized "Secret" announcement) that he had discovered that the Nazis were behind the Comminists, and that Scientology's enemies were actually Nazis (and should be characterized, when possible, as Nazis).
Two years earlier, Hubbard introduced his Propaganda Tech, a "Tech" that he appears to have been using for many years privately (mixed with his paranoia).
L. Ron Hubbard explained how to use propaganda in the confidential HCOPL 'Battle Tactics' of 16 February 1969:
"The only safe public opinion to head for is they love us and are in a frenzy of hate against the enemy, that means standard wartime propaganda is what one is doing... Know the mores of your public opinion, what they hate. That's the enemy. What they love. That's you."
And from Hubbard's 'Black Propaganda' of 12 January 1972:
"The objective is to be identified as attackers of popularly considered evils. This declassifies us from former labels. It reclassifies our attackers as evil people."
In 1968, came 'Ron's Journal 68'. In it, Hubbard discussed tactics for influencing public opinion:
"...And the general attack line is along the line of human rights; yes human rights...
"Now I'll give you a clue on how this is handled, somebody comes up to you and he's hostile - he's hostile to Scientology... and you say 'why are you against human rights?', and if you know anything about human rights like the Universal Declaration of human rights, United Nations - that sort of thing you know if you know something about this subject you just follow it right straight up - in other words you don't defend Scientology, you just attack along this line of human rights.
"Tell him or her, the hostile person, the hostile press - for instance a newspaper writes an article on how bad Scientology is - any Scientologist reading this should run right to that newspaper and demand: 'Why are you against human rights?'...
"Whereas an attack on Scientology is actually an attack on human rights - anyone making an attack on Scientology is an attack on human rights...
"Each time Scientology is attacked, we build into society, if you do this, we'll build into society an actual stimulus response mechanism whereas an attack on Scientology is an attack on human rights..."
(Just in case anyone is wondering about the inspiration for Scientology's numerous front groups having to do with "Human Rights." Plus, another pattern is touched upon - and bit of confidential Tech - that of using "aberrative" behavior and "enemy" tactics on others, including, it turns out, the trusting Scientologists.)
Travelling back, before the Vietnam war and the shift in public opinion (with young people far more concerned about fascists and Nazis than with communists), here's another example, from an 'Executive Directive' of 26 September 1966, of Hubbard using his own "Propaganda Tech" by way of his hoax 1955 "Russian textbook":
"We are probably the only group, church or healing, in this field that refuses to be degraded. Have you ever seen the 'Brainwashing manual'? It... explains why we are occasionally targeted... [the Commies are behind the attacks]. You can have copies of it free if you spread them around town... Our current attackers are walking straight into a minefield. Personal ruin faces each of these few attackers the moment we start our campaign..."
Hubbard's (perceived and/or advertised) "enemies" definitely included big corporations, bankers, and research foundations. (yet, behind the scenes, throughout the 1950s at least, Hubbard was offering his services to these same "enemies," or bragging that these "enemies" wanted him to work for them, or that he had at one time worked for them, etc.)
Hubbard has - in one statement - these as showing no interest in funding Dianetics/Scientology, and yet - in another statement - has them attacking Dianetics/Scientology because they can't own it. In one statement, Scientology is attacked because it (its mental therapy) "works"; in other statement, Scientology is attacked because it's (mental therapy) isn't being applied properly and so isn't working as it should.
So Hubbard's list of "enemies" was long, but (during the 1950s and 1960s) the "Communists" were at the top of the list.
Hubbard told so many tales, and was using his own 'Propaganda Tech' on others, including his own followers, for so long, that quoting his comments in lectures (and assorted inspirational writings to Scientologists) can be confusing to some who haven't decoded "trickster" Hubbard's methods.
What's more confusing is that some of his writings (or at least writings attributed to him) appear to be brilliantly innovative and - yes - quite sane.
For example, there's a 'PAB' ('Professional Auditors Bulletin') in which, appended to the end of the 'PAB', Hubbard wrote of Scientology: "Keep it free." And these words make Scientologists swoon in appreciate awe, enhancing their sense of trust in their spiritual leader, L. Ron.
But "keep it free" from what? Well, the Them! The Commies, and the Nazis, and the Marcabians! and even, sometimes, the Capitalists: THEM.
This 'PAB' was, as I recall - practically - the pinnacle of sanity for Scientology, yet in the background, lurking, was Hubbard's nuttiness, paranoia, need to deceive and manipulate, and self serving hidden agenda; and it would be only a few months until (1958) Hubbard ordered another printing of his fraudulent "Russian Textbook on Psycho-politics," to be handed around so as to influence public opinion favorably toward Scientology, which was depicted as being attacked by Russian Communists.
(No wonder the trusting "taped path" to "Total Freedom" and "OT" walkers are as lost in the Hubbard labyrinth as they are - as they attentively watch their e-meters for the next read on their "next step," etc.)
However, Hubbard could vary his approach if it seemed advantageous to do so, briefly instructing, to a selected audience, that Scientology be identified as anti-Capitalist.
In a 6 October 1965 (broadly circulated) 'Executive Letter' Hubbard announced, "McCarthyism has many faces. It is still abroad today."
And in another (non public) issue, 'Enquiry Rumor UK' of 9 February 1966, Hubbard (privately) explained:
"Couple the words psychiatry with Capitalism - allege that psychiatry is the Capitalist's tool. A Conservative opened the attack in the UK and found the Press beating the drum for us."
When this approach did not prove effective, Hubbard quickly resumed his prior long standing tactic of calling his enemies "communists," etc.
Prior to 1971, Hubbard portrayed his ex-wife, Sara, as working for the Comminists, after 1971, he had her working for the Nazis. In 1969, when he was still using the Russian Communist "button," he even concocted the name "Sara Komkovadamanov."
Hubbard knew it was a contrived name - he wasn't that crazy - just as he knew that "Charles Stickley," the name used in the "Editorial Note" (which he wrote) in the front of his hoax 1955 "Russian textbook" was contrived.
Hubbard knowingly lied repeatedly, including to Scientologists, and yet, accompanying those lies, there was that (very sincere) paranoia, and that was part of the mix too.
