We all hope that the wars all around the world end. But what happens when they do? How should perpetrators be punished? How should victims be compensated? And what should be done to avoid a relapse into violence? We ask those questions to Professor Stephan Parmentier. He is an expert in transitional justice from the University of Leuven. With him, we discuss examples such as Nazi Germany, Spain, and South Africa. The examples show, that there are right and wrong ways of handling post-conflict situations.
