Regarding This Being A Myth From The Left-- These people have linked themselves together through ideology and membership (if I recall the membership thing correctly) in an organization or organizations. And-- They have published papers, etc. One of which, the author of this article gives. Further-- Several of these people have been in the position to decide and implement policy. No One-- Has to make up things about Neo-Cons. And-- It's relatively easy to see their policies in action/non-action...and find other information about them.
