If anyone is really interested in Ron Paul and his core beliefs please read his book "A Foreign Policy of Freedom" 'Peace, Commerce, and Honest Friendship'.
I found it here, it is not expensive.
The Freedom Page
It is a compilation of his time in the HR from 1976 to 1984, his time out of Congress, and 1997 to 2006. I'm at his time out of Congress. The book is an excellent read and it is a fantastic history lesson. His stance has not changed, he has not wavered, flip-flopped or changed his views. Anyone interested in how our foreign policy of yesteryear has influenced today get this book.
