To understand Serbian nationalism requires profound attention to history and careful analysis. Cohen accomplishes both through years of studying primary sources never before translated, focusing on World War II and uncovering the foundations of ethnic cleansing. He argues that the Serbs collaborated with the Nazis in contrast to later Serbian rhetoric that claimed the Serbs were victims, "the thirteenth tribe of Israel." This official duplicity veiled the true objectives of the government to create an ethnically pure homeland. Annotation c. by Book News, Inc., Portland, Or.
