I’ve read the 5 steps you list before. Can’t remember if it was ‘Tragedy and Hope by Quigley’ or the Communist Party Platform of the 1950’s or where though.
My sources spans more than one researcher that researched another source. I usually make an attempt to find the original sources if possible. I have found that many original sources come from prior to the late 80’s. It seems that original sources in prior to the 80’s are hard to come by. Two original sources were very costly. “The Plot to Seize the White House”...500.00 + and “The Changing Images of Man” (Systems science and world order library)
by Markley...for 170.00 +/- the internet is full of them as you already know. The Iron Mountain Report is another good source that is the sister to the Changing Images of Man.
The source for the 5 Steps is the following:
“Here’s The Proof”, by Robert Concoby & David Nicol; 1994, P 80.
This is a very good source or summary of the whole conspiracy....this paperback is hard to find. They, like all the others do cite Quigley quite a bit. Quigley is only about 1400 pages long....:)
