Brainstorming should be appreciated here, Just wanna add if you make it more clear by adding international perspective (Holocaust, Iraq & Afghan war, ISIS etc), National Perspective (Dictatorship, feudal system in some areas, etc), Economic perspective ( Economic sanctions on North Korea, Iran but aid to Israel), Social Perspective (Justice system, treatment in police stations , health sector etc), Gender Perspective ( male dominant society, Women missing basic rights etc) and so on...
