Our world is burning and human hearts are heavily polluted with hate, whickedness and the madness of the power under the dictatorship of weapons. Wealth is built from innocent bloodshed and hostage practices. Earth, our common house, instead of being a paradise has been transformed into hell. In this book, we present few recent or ongoing wars as cases of study to better illustrate human whickedness. The aim of this publication is to remind every human that violence increasingly and sustainably generates violence. We need to promote positive values such as Love, Justice, Charity and Peace. It is not possible to heal wounds without attacking the cause. You cannot stop smoke when you keep the brazier on. Russo-ukrainian war, Rwanda-M23 - D R Congo War, Israeli-Hamas-Palestinian war, etc. are teaching cases presented in this book. Their common cause is the pollution of human hearts with hate. We therefore strongly recommend the rebirth of hearts to promote love and peace worldwide. The dictatorship of weapons and madness of power are destroying our humanity.
