Why do some states collapse in crisis while others adapt and thrive?The Spontaneity Framework in International Relations advances a bold new theory of survival in a turbulent world. Introducing Dynamic Adaptive Realism (DAR), the author argues that resilience depends not on static power but on adaptive capacity-the ability to institutionalize spontaneity through redundancy, experimentation, and cognitive flexibility. Through case studies of India, China, Venezuela, North Korea, and Russia, the book contrasts adaptive agility with rigid fragility, offering both scholarly insight and practical policy relevance. Timely and original, this work reframes power for the twenty-first century: adaptation is strength, and spontaneity is survival.
