A Winner of the Association for the Study of the Middle East and Africa 2023 Bernard Lewis PrizeLandes, a medievalist and historian of apocalyptic movements, takes us through the first years of the third millennium (2000-2003), documenting how a radical inability of Westerners to understand the medieval mentality that drove Global Jihad prompted a series of disastrous misinterpretations and misguided reactions that have shaped our so-far unhappy century. These misinterpretations in 2000, 2001, 2002, and 2005, contributed fundamentally to the ever-worsening moral and empirical disorientations of our information elites (journalists, academics, pundits). So while journalists reported Palestinian war propaganda as news (lethal journalism), they were also reporting Jihadi war propaganda as news (own-goal war journalism). These radical disorientations have created our current dilemma of pervasive information distrust, deep splits within the voting public in most democracies, the politicization of science, and the inability of Western elites to defend their civilization, and instead, to stand down before an invasion.
