As states find themselves in conflicts with nonstate actors, they often target other states that harbor or aid these challenging opponents. Wendy Pearlman and Boaz Atzili investigate this strategy, which they term triadic coercion: why states pursue it and the conditions under which it succeeds, across seventy years of Israeli history. A significant and multifaceted accomplishment. A must-read for scholars of the Israeli-Arab Conflict, it innovatively blends realist and constructivist approaches.
