In this powerful and thought-provoking book, Sundeep Waslekar examines the history and politics of war and offers solutions for achieving world peace by ending the arms race. The invention of dangerous weapons, such as hypersonic missiles, killer robots and deadly pathogens, along with the rise of nationalism and intolerance, has made the human civilization more vulnerable today than it has ever been before. It might endure terrorist attacks, climate change and pandemics, but humankind cannot survive a global war involving nuclear weapons. Most people live in denial of such an existential risk because they feel it is not imminent. For them, this book serves as a wake-up call.
