In The New Calculus of Escalation, Martin C. Libicki redefines how we understand the thresholds between peace, conventional war, and nuclear conflict in an era shaped by cyber warfare and emerging technologies. Drawing lessons from the Russia-Ukraine war and Cold War doctrines, he offers a fresh framework for managing escalation to prevent catastrophic outcomes. This timely and thought-provoking book is essential reading for strategists, policymakers, and anyone concerned with the future of great power conflict.
