Cost Asymmetry And Escalation Dynamics: Extending Deterrence Theory For The Drone Age

Growing economic asymmetry between inexpensive offensive systems and costly defensive architectures is reshaping escalation dynamics in contemporary warfare. Focusing on the period from 2022 to the present, the analysis examines case studies from the Russia-Ukraine war, Iran's regional strategy in the Middle East, and recent India-Pakistan crises in South Asia. Drawing on insights from strategic studies, defence economics, and military innovation literature, an analytical framework - the Escalation Cost Curve - is developed to explain how sustained cost-asymmetric attacks can strain defensive inventories, compress decision timelines, and potentially lower thresholds for escalation. Intended primarily for prolonged conventional, cost-intensive conflicts, the framework extends existing deterrence theories by specifying how economic strain, rather than military force alone, can shape strategic outcomes, while acknowledging that adaptation, target value, and alliance support moderate this relationship. Future warfare will increasingly be shaped by economic sustainability alongside technological superiority and military capability.
