Generations raised after the Second World War took for granted a world of stability and prosperity, and with it the waning of ancient hatreds. Recent decades have been more sobering. Instability and extremism have returned in force. As Shalom Lappin explains in this worrying book, an upsurge of antisemitism across the political spectrum has accompanied them. Recent events in the Middle East have transformed it into a tidal wave.

Lappin explores in particular the disturbing correlation between the expansion of economic globalization and the return of the anti-Jewish ideas that we thought had been consigned to the past. He examines this relationship within the context of the assault on democracy and social cohesion that anti-globalist reactions have launched in different parts of the world. To understand contemporary antisemitism, Lappin argues, it is essential to recognize the way in which its antecedents have become deeply embedded in Western and Middle Eastern cultures over millennia. This allows hostility to Jews to cross political boundaries easily, left and right, in a way that other forms of racism do not. Combatting antisemitism effectively requires a new progressive politics that addresses its root causes.

The New Antisemitism is crucial reading for anyone concerned with the social pathologies unleashed by our current economic and political discontents.
