This review essay engages critically with Heikki Patomäki's The Political Economy of Global Security: War, Future Crises, and Changes in Global Governance. The book is built around the hypothesis that the current ‘era of Neoliberalism’ shares many similarities to the era of the ‘new imperialism’ of the late nineteenth century, ending, catastrophically, in World War I and the Great Depression. Patomäki undertakes this comparison by focusing on the principal long-term historical processes, structures, tendencies and contradictions that may be responsible for (...) the similarities between these two eras. To do so Patomäki constructs an explanatory model of the underlying causal processes and mechanisms involved. The implications are ominous and urgent. The essay uses a close examination of this exemplary case of critical realism in social science to discuss critically its historical explanations, the comparative analysis it makes, and especially the question of agency as theorised in the author's ‘future scenarios’.
