This book presents the findings of a mixed methods analysis of forty years of military interventions by great powers into wars of regime change. We show that such interventions are performances, sometimes joined by their allies and clients in team performances of great powerness. The interventions follow bilateral arms deals conducted in a previous period. Great powers are only great insofar as they protect their clients and allies, push out and deter rival powers, and punish rogue regimes. Each logic of intervention requires a different framing of the nature of the problem and justification for intervention to coordinate the conflicts that consistently take place on the edges of competing security hierarchies.
