Defence without deterrence: India’s strategy in the 1965 war

Why does combat success sometimes fail to produce a stable and durable post-war settlement? In the 1965 war, India successfully defended against a Pakistani invasion, but did not improve the long-term security of Kashmir or establish deterrence against Pakistan. I argue that, to deter rivals after war, states must couple battlefield success with credible signals of resolve, such as retaining captured territory or risking a wider war. In 1965, India used both denial and punishment strategies, but both failed to establish post-war deterrence because it judged the necessary signals of resolve to be too costly.
