THE NAKED COMMUNIST by W. Cleon Skousen was written in the ‘50s, I believe, and enumerates the communist strategy for destroying the America we once knew. They have accomplished almost all of their goals, but we should never give up the fight to save America. Ignorance and complacency of the overall population are the communists greatest assets.
If you can’t find a copy of the Skousen’s book there is a similar book (REPEAL AND REPLACE AMERICA by Jim Spurlock) which is a recent offering and pulls a lot of info from Skousen’s book.
