A stumbling block for Revisionists, just as it was for the post-war German defendants, is the seeming wealth of documents and testimony assembled by Allied prosecutors for the Nuremberg trials. The more than sixty volumes of trial material which appeared in the wake of the "Trial of the Major War Criminals" and twelve subsequent trials before the (American) Nuremberg Military Tribunal have for many years supplied a massive compilation of apparently damning evidence against Germany's National Socialist regime. Most Exterminationists, academic and lay, believe that Germany's "aggression" in beginning the war, and the numerous atrocities and war crimes laid to the German account, above all the alleged Holocaust of European Jewry, are amply documented in the so-called "Nuremberg record".
