This paper explores the relationship between utopian ideologies and genocide prevention. Many of the worst genocidal and human rights excesses of the last century were perpetrated under the guise of creating a more perfect society and world. These utopian ideologies were marked by totalizing ways of thinking that involved applying ideal world beliefs onto imperfect political, social, and cultural social systems. In many ways the movement to prevent genocide can also be seen as making certain assumptions about the perfectibility of human political and social institutions and I intend to explore some of the potential pitfalls inherent in making these kinds of assessments. In the interests of creating a genocide free world, do we run the risk of fostering attitudes and policies that are ultimately harmful to groups and societies that don䴜t fit into the projected mold? Does the movement to prevent genocide run the risk of becoming a force that subscribes to end justifying the means type of arguments? Can genocide be prevented without implementing a kind of new interventionist imperialism?
