Beginning with his doctoral thesis at Princeton , Finkelstein 's career have been marked by controversy . A self @-@ described " forensic scholar " , he have written sharply critical academic reviews of several prominent writers and scholars whom he accuse of misrepresenting the documentary record in order to defend Israel 's policies and practices . His writings have dealt with politically charged topics such as Zionism , the demographic history of Palestine and his allegations of the existence of a " Holocaust Industry " that exploit the memory of the Holocaust to further Israeli and financial interests .
