Cognitive Warfare and India’s Deterrence Challenge

India’s response to Pakistan-backed terrorism has shifted from strategic restraint towards calibrated deterrence by punishment. The surgical strikes of 2016, the Balakot air strike of 2019 and Operation Sindoor demonstrated India’s willingness to impose direct military costs while retaining political control over escalation. The purpose of this approach is not merely retaliatory, but designed to alter Pakistan’s calculation of the risks associated with supporting or permitting another major terrorist attack. However, the effectiveness of this strategy depends not only on the policy signals and damage inflicted, but also on the conclusions Pakistan draws from the use of force. 

In this in-depth analysis, the author observes that military action alone does not determine its own deterrent effect; what matters more is the lesson that Pakistan draws from it. Cognitive warfare complicates this process by contesting operational outcomes, shaping perceptions of capability and resolve, and advancing competing explanations of escalation and conflict termination. 

Operation Sindoor illustrates this challenge. India viewed the confrontation as demonstrating its ability to strike at considerable depth, respond to Pakistani retaliation and retain further military options. Pakistan portrayed its response as evidence that Indian action could be resisted and contained. The result was deterrence ambiguity. India could conclude that it had expanded the space for calibrated punitive action, while Pakistan could conclude that its retaliation remained capable of limiting that action. 

This ambiguity could well shape behaviour in a future crisis. Both countries may enter the next confrontation with greater confidence in their ability to employ force and manage escalation. Pakistan’s public narrative of victory, amplified through a contested information environment, could also narrow the political space for restraint. 

The author argues that India must treat the cognitive dimension as integral to deterrence, rather than as post-crisis management. Planning should define the deterrent effect India wants Pakistan’s military-security establishment to draw, while deterrent success should be assessed through changes in Pakistan’s behaviour rather than through Indian declarations alone. 

India should also use the period between crises to reinforce the costs attached to terrorism through diplomatic, economic and legal instruments and preserve the credibility of its deterrent signals through timely, accurate and coordinated communication. Furthermore, it should account for third-party amplification of narratives, as seen in the contested claims about Chinese versus Western platforms during Operation Sindoor. 

The author concludes that the lasting test of Operation Sindoor will not be which side presented the more persuasive account of the confrontation. It will lie in the choices made by GHQ in Rawalpindi before the next crisis. India’s deterrence will have been strengthened only when Pakistan concludes that another major terrorist attack would trigger consequences that are difficult to contain and no longer worth the risk they will entail. 

In bringing clarity to these critically important issues, this brief will be of considerable interest to India’s policymakers, the strategic community and the Indian military.
