A former CIA analyst draws on his experience combatting jihadi terror movements and the history of totalitarian regimes to show how citizens lose touch with reality. Buck Sexton explores why some of history's greatest empires have devolved into genocidal lunacy--often with shocking compliance from their own people. He outlines eight tactics of mass delusion through examining: how Stalin used Pavlovian mind games to establish absolute control; how Chinese thought reform transformed opposition into terrorized pawns; and how Jihadist preachers replace shared humanity with weaponized fear.
