Air Power Under the Nuclear Shadow: Operation Sindoor and the Logic of Strategic Restraint

Operation Sindoor (May 2025) represents a significant development in the evolution of air power, deterrence, and limited war in South Asia. Conducted in response to the Pahalgam terrorist attack, the operation involved precision strikes against terrorist infrastructure in Pakistan and Pakistan-occupied Kashmir while deliberately avoiding Pakistani political leadership, critical national infrastructure, and core military command structures. This article examines Operation Sindoor through the analytical lens of John Warden’s Five Rings Model and argues that the operation reflected a modified application of classical air power theory. Rather than seeking systemic paralysis through attacks on the adversary’s inner strategic rings, India employed selective targeting and strategic restraint to generate coercive effects while managing escalation risks amid mutual nuclear deterrence.

Rather than seeking systemic paralysis through attacks on the adversary’s inner strategic rings, India employed selective targeting and strategic restraint to generate coercive effects while managing escalation risks amid mutual nuclear deterrence.

The study demonstrates that the significance of Operation Sindoor lay not only in the targets that were struck but also in those deliberately left untouched. By focusing on terrorist infrastructure while avoiding state-centric targets, India sought to impose costs, communicate resolve, preserve legitimacy, and maintain escalation control simultaneously. The article further situates the operation within broader debates on coercive diplomacy, limited war, and deterrence in South Asia, drawing on the works of Thomas Schelling, Robert Pape, Vipin Narang, Walter Ladwig III and Rajesh Rajagopalan.

The article argues that Operation Sindoor reflects an emerging pattern in India–Pakistan crises in which military force functions less as an instrument of decisive victory and more as a mechanism of strategic communication. The recurring trajectory from Uri (2016) to Balakot (2019) and Sindoor (2025) suggests the evolution of a distinct South Asian model of limited war under the nuclear shadow, where calibrated force, selective targeting, and escalation management are central to deterrence practice. The study contributes to both air power theory and South Asian strategic studies by highlighting how contemporary military operations increasingly derive effectiveness from restraint as much as from destruction.
