Thanks to the expanded influence of Muslim Brotherhood operatives and other influential Islamic supremacists, the U.S. government's official counter-terrorism policy has now mutated into something called Countering Violent Extremism (CVE). Words matter. And in the present phase of what we call "The War for the Free World," it is of the utmost importance to the national and homeland security that the United States' first lines of defense be free to use the correct words to: name and define the enemy; describe accurately its threat doctrine; and develop and implement an effective strategic plan of action for victory. This book traces the course of one of the most successful influence operations in American history: the Muslim Brotherhood's penetration and increasing success at subordinating our security to its jihadist agenda. That agenda is designed to prevent us, first, from properly understanding our foes and thereafter, incrementally to dismantle our ability to resist them.
