"Berman shows how a genuine spiritual inspiration can be twisted into a fanatical demand for murder. He offers remarkable insights into the trends and conflicts influencing Islamic radicalism. He illuminates the surprising connections between very different political movements, and he reveals the several ways in which Islamic extremism resembles some all-too-familiar episodes in American and European experience.". "Berman draws on sources that range from Albert Camus's The Rebel to the Book of the Revelation - from Lincoln's Gettysburg Address to the Islamist scholar Sayyid Qutb's magisterial In the Shade of the Koran. Berman condemns the foreign policy "realism" of the political right, and he diagnoses the naivete of the political left. He calls for a "new radicalism" and a "liberal American interventionism" to promote democratic values throughout the world - a vigorous new politics of American liberalism."--BOOK JACKET.
