Sustainable peace after conflict requires reconciliation of former adversaries. But, people in post-conflict societies often resist or even reject reconciliation both as a concept and practice. While reconciliation may be desirable, the question is: can people reconcile in the aftermath of mass atrocity, and how do we know they can? Drawing on her examination of the Balkans conflicts, Kostovicova discusses a novel approach to evaluating the effects of transitional justice in post-conflict societies and its policy implications presented in her book Reconciliation by Stealth: How People Talk about War Crimes.
