The Dershowitz–Finkelstein affair was a public controversy involving academics Alan Dershowitz and Norman Finkelstein and their scholarship on the Israeli–Palestinian conflict in 2005.
Shortly after the publication of the book The Case for Israel, by Harvard Law School professor Alan Dershowitz, Norman Finkelstein alleged that it was "a collection of fraud, falsification, plagiarism and nonsense." Finkelstein further derided the book, remarking, "If Dershowitz's book were made of cloth, I wouldn't even use it as a schmatta ... his book is such garbage." Finkelstein charged that Dershowitz had engaged in plagiarism in his use of Joan Peters' book From Time Immemorial. Dershowitz has denied the charges. Former Harvard president Derek Bok, following a review requested by Harvard Law School Dean Elena Kagan, determined that no plagiarism had occurred.
In Beyond Chutzpah: On the Misuse of Anti-Semitism and the Abuse of History, published by University of California Press on August 28, 2005, Finkelstein aimed to debunk The Case for Israel. Dershowitz had written letters to both the The New Press and to the University of California Press to prevent its publication, claiming it contained massive libel and stating that the book should not be published. Dershowitz responded in his book The Case for Peace and alleged a politically motivated campaign of vilification spearheaded by Finkelstein, Noam Chomsky, and Alexander Cockburn against several pro-Israel academics.
