 Although on the operative and tactical level, the Research Department has often proven quite successful, on the strategic and political front it has committed crucial failures which had a decisive impact on the course of Israeli and regional history.Above all others, the failure to warn that the Yom Kippur War was imminent, remains the Research Department's greatest blunder.The Agranat Commission, which investigated the failures of the war, very severely criticized Research in particular and the Intelligence Community, in general.
