This is a sharply written and most welcome new contribution on our ‘New Age of Genocide’ – the multiple new genocides of the 21st century. Part I reviews how genocide is returning, yet again, despite our hope it would not be back. But genocide is now returning to ‘the centre of a brutal new constellation of world politics’ (p. 1). So does the concept of genocide, under renewed debate. Shaw’s book was originally prompted by Russia’s 2022 invasion of Ukraine. He discusses the ’dynamics of war, genocide and occupation’, and the fate of the ’genocidal occupied zones’ that Russia is holding on to. Then, Gaza erupted in 2023. Shaw decided to expand the book to its present scope. In Part II, on Israel-Palestine, he builds on his longtime research, re-assessing the ‘structure of genocide in Palestine’ and regional history as a whole, in the light of the genocide concept. Discussing the renewed debates prompted by Ukraine and Gaza, Shaw notes how many other new genocides are left out of view: Sudan, Myanmar, etc. Europe and the Middle East are the focus of Western public attention, and Gambia’s ICJ case on the Rohingya mostly set the stage for South Africa’s later case against Israel. (But here Shaw unfortunately himself becomes an illustration of the silencing trend, omitting China's massive Uyghur genocide). Nevertheless, Shaw makes highly perceptive observations on genocide today. I especially appreciated his rewarding discussion in Part III, with a thoughtful defense of the genocide concept, against those misguided scholars who now wrongly seek to discard it. Instead, he advocates reclaiming it and using it in new ways (‘Theses on genocide thought and action’, pp. 177 –179).
