Democracy from Above addresses the intersection of two important political phenomena: the influence and proliferation of regional international organizations (IOs), and the sources of democratization. The central finding is that regional organizations both facilitate transitions to democracy and enhance the survivability of young democracies. With respect to the democratization literature, the book’s message is that external factors must be considered alongside domestic-level variables, the primary focus of scholars in this area. For students of international relations, Pevehouse expands our understanding of how IOs matter—including their ability to penetrate domestic politics—and shows that variation among them must be taken seriously. He also provides one of the most convincing empirical refutations to date of the Realist view that institutions merely reflect the forces of power politics. Alongside its contribution to these academic debates, the book is timely from a policy standpoint. By showing that membership in regional fora can help induce and nurture democracy, the findings highlight a type of international political engagement capable of promoting liberal reform. At a time when external imposition of democracy in Iraq is proving arduous at best, the promise of alternative pathways is especially welcome. Pevehouse suggests a number of causal mechanisms—too many to summarize here—by which the salutary effects of regional IOs on democracy occur. While some of the hypothesized mechanisms are international (e.g., states can use these organizations to pressure or offer incentives to authoritarian members or would-be members), the majority transpire in the domestic realm. The most important effects come from the conditionality associated with membership in regional organizations. By accepting these conditions, reforming governments can bind themselves and enhance their legitimacy during both the transition and consolidation phases. This minimizes opposition from publics and competing elites, especially business groups
