"INFILTRATION may be the closest thing we see, in this global conflict, to the invaluable ‘Enigma’ machine of World War II. In this powerfully written and carefully documented book, Paul Sperry breaks the code on the nature of our Islamist enemies, their plans for the destruction of America's government and society and just how far advanced is the execution of those murderous plans."
—Frank J. Gaffney, former assistant secretary of Defense under Reagan and president of the Center for Security Policy in Washington

"Very powerful."
—Walid Phares, Florida-Atlantic University professor and Islamic terrorism expert

"I couldn't put it down."
—U.S. Congressman Tom Tancredo, chairman of the Immigration Reform Caucus

"INFILTRATION has lots of new information. This book deserves lots of attention."
—Daniel Pipes, founder of the Middle East Forum

"INFILTRATION definitely belongs in the hands of every American even remotely concerned about the Islamic threat to America."
—Andrew Whitehead, Anti-CAIR founder

"Epic."
— Dale Hurd, senior reporter, CBN

"Sperry has marshaled a lot of information including things I'd never read before, and that's saying a lot. This is an impressive piece of work."
—Shaun Waterman, UPI Homeland Security Editor

"One of the best books on the Islamic threat that's been written so far."
—Paul Weyrich, chairman of the Free Congress Foundation

"Gutsy and honest—the way reporters used to write."
—Steve Elson, former FAA special agent and Navy SEAL

"It should be used as standard text for training."
—Det. Terence Murphy, NYPD intelligence division

"Informative and disconcerting."
—Sgt. Kevin Dougherty, Miami-Dade Police Department

"INFILTRATION is excellent! Pointing out the penetration of the U.S. government by the PSYOPS and Civil Affairs part of the international Islamist movement is a great public service. I plan on adopting the book for my Intel Analysis class in the Fall."
—Peter Leitner, Pentagon official and George Mason University lecturer

"Powerful."
—Brian Sullivan, former FAA special agent and director of risk management, New England region of FAA
