Certainly claims of massacres and atrocities should not go without investigation. The problem is that, like the case of Dir Yassin, even when the claim is shown to be unfounded, the legend persists. It is convenient for the enemies of Israel to portray her armed forces as ruthless savages, but that propagandistic position cannot be supported by any facts.

For example, Tantura. A Haifa University revisionist historian, Theodor Katz, claimed in his M.A. thesis (released January 2000) that an IDF unit had massacred over 200 Arab residents of the village of Tantura in the 1948 War of Independence. He was brought to court in 2001 by surviving officers and men of the unit who presented contrary evidence including review of Katz's tape recordings showing how he had manipulated the testimony of survivors. Katz admitted finally that he had selectively used reports from Arab sources, taking only those that supported his thesis. The lawsuit was dropped after Katz signed a renunciation of his own work and Haifa University pulled the thesis from library shelves. [It was revealed in September 2002 that tormer Palestinian Authority minister Feisal Husseini paid $8,000 for the legal defense of Teddy Katz.] The University conducted its own review of the evidence. After six months of work, the committee had managed to review only a little more than one-fourth of Katz's tapes, mostly in Arabic, which bore direct relation to the question of whether any massacre took place. Yet even in that limited selection, 14 major discrepancies - in which the tapes didn't accord with the written text - came to light.

No pro-Palestinian Arab source had ever pointed to a massacre at Tantura before Katz's thesis appeared in 2000. The thesis has been completely debunked. Nonetheless, there are now hundreds of web sites that cite the "Tantura massacre" as historical fact. And while Arab sources rushed into print to trumpet the news of Katz's thesis, none has mentioned the retraction save a few who cite it as an example of a massive coverup.
