The literature on international security for the last three decades has primarily focused on the twin problems of terrorism and insurgency as the principal threats to the global status quo, and in doing so has neglected the role of conquest as an instrument within great power competition. The emerging era of bare-knuckled territorial aggrandizement by revisionist great powers, therefore, has largely caught the academy underprepared. Given this, I offer a ten-year anniversary review of a book that could assist in shaping our understanding of the changing nature of the international system today.
