Political Consequences of Military Strategy: Expanding and Refining the Spiral and Deterrence Models

Analyses of military strategy often overlook its political consequences—its effect on the adversary's basic goals and understanding of the defender's resolve. As a result, they prescribe the wrong type of military policy and reduce states' security. This article explores how a variety of factors interact to produce political consequences. These factors include the type of adversary (specifically, its motives for expansion); the type of military strategy the defender adopts (offensive or defensive and unilateral or bilateral); the source of the adversary's misperceptions; and the process through which political consequences are generated. The article reformulates Jervis's spiral and deterrence models and argues that they overlook types of adversaries, including most importantly insecure greedy states; that shifts in the adversary's balance of domestic power offer an alternative to individual learning as the basic way in which political consequences are generated; that national-level failures of evaluation provide an alternative source of exaggerated insecurity; and that these differences can require the defender to follow different policies. Final sections explore military options for managing political consequences and implications for U.S. security policy.
