Combining political theory and sociological interviews spanning four countries, Israel, the USA, Canada and the UK, Ilan Zvi Baron explores the Jewish Diaspora/Israel relationship and suggests that instead of looking at Diaspora Jews’ relationship with Israel as a matter of loyalty, it is one of obligation. Baron develops an outline for a theory of transnational political obligation and, in the process, provides an alternative way to understand and explore the Diaspora/Israel relationship than one mired in partisan debates about whether or not being a good Jew means supporting Israel. He concludes by arguing that critique of Israel is not just about Israeli policy, but about what it means to be a Diaspora Jew.
