Mass murder in the service of a totalitarian ideology is, sadly, a key feature of the interesting times in which we live. Fear and rage are natural reactions, but we also need sober, clear-sighted analysis of the phenomenon, and that is what Peter Neumann provides in this study published in 2016. Neumann, a German academic working in Britain, starts by sketching a history of what he calls the four waves of modern terrorism: the anarchists, the anti-colonialists, the New Left and now the religious wave. He traces jihadism's lineage from the Muslim Brotherhood up through the Islamic State, cautioning that "the history of Islamism is not the history of Islam" while acknowledging that Islamic terrorism is by far the most prominent strain in the current wave and attempting to determine why this should be. He profiles the leading figures, from Bin Laden up through al-Baghdadi, and describes the process of radicalization of young European men (few women and few Americans) who commit to jihadism. In the final section he discusses the problems and prospects of a free society in defending itself against murderous fanaticism.
Not a cheerful read, but invaluable in understanding the nature of the enemy we face.
