The military conflict in Southeastern Ukraine provides vast research opportunities in most diverse areas and in a zone of ongoing combat with all its attendant social ramifications. This article provides a review of some key questions of this war: why volunteer battalions conduct some harmful and inhumane acts and what may be done next to prevent violence after the war.
