In 1849, Victor Hugo called for the abolition of the death penalty, today, 176 years later, Martí Olivella proposes an equally urgent goal: to abolish war. This book presents strategies and proposals for Nonviolent Self-Defense with Civil Deterrence to prevent armed conflicts, making violence unprofitable for any aggressor. It defends the right to protect oneself without giving up ethics or effectiveness. This proposal promotes a security paradigm that is highly relevant to our times and fosters a peaceful and democratic global movement. A path as necessary as it is useful.
